Hiç bir görüntüyü büyütmek için yeniden boyutlandırmayı denediniz ama bunun yerine görüntü kalitesini kaybettiniz mi?
Bir görüntüyü büyütmeye çalıştığınızda, bulanık ve profesyonel olmayan görünebilir. Bir resim binlerce pikselden oluşur ve boyutunu büyüttüğünüzde bu pikseller görünür hale gelir.
Sonuç olarak, donuk ve düşük kaliteli bir görüntü elde edersiniz.
Blog yazma konusundaki uzun yıllara dayanan deneyimimizde, görsellerin içeriğinizi oluşturabileceğini veya bozabileceğini öğrendik. Görselleriniz bulanık görünüyorsa, bu durum kullanıcı etkileşimini azaltabilir ve markanıza zarar verebilir.
Neyse ki bu sorunun çözümleri var. Gelişmiş görüntü düzenleme yazılımlarını, görüntü kalitesini koruyan algoritmaları veya görüntüleri yeniden boyutlandırmak için tasarlanmış çevrimiçi araçları kullanabilirsiniz.
Bu makalede, görüntüleri kaliteden ödün vermeden büyütmek için nasıl kolayca yeniden boyutlandırabileceğinizi göstereceğiz.
Görüntüler Büyütüldüğünde Neden Kalite Kaybeder?
Bitmap, web’de en yaygın kullanılan görüntü formatıdır ve tüm JPEG ve PNG dosyalarınız bitmap görüntü dosyalarıdır.
Bir bit eşlem görüntüsü binlerce pikselden oluşur. Yakınlaştırırsanız, bu pikselleri aslında kareler olarak görebilirsiniz. Her piksel görüntü üzerinde sabit bir konuma eşlenmiştir, bu nedenle bitmap adı verilmiştir.
Çoğu görüntü düzenleme yazılımı bir görüntüyü yeniden boyutlandırmak için bu pikselleri küçültür veya büyütür. Bu nedenle bir görüntüyü daha küçük bir boyuta yeniden boyutlandırdığınızda görünür bir kalite kaybı olmaz, çünkü bu pikseller daha az görünür hale gelir.
Öte yandan, WordPress’te bir görüntüyü yeniden boyutlandırarak büyüttüğünüzde, bu büyütülmüş pikseller daha görünür hale gelir ve görüntünün bulanık ve pikselli görünmesine neden olur.
Çözüm, büyütülen her pikseli etrafındaki piksellere benzeyecek şekilde ayarlamaktır. Bu yönteme Fraktal İnterpolasyon veya kısaca Fraktallar denir.
Not: Her zaman önce yüksek çözünürlüklü bir görüntü ile başlayın. Orijinal görüntüdeki piksel sayısı ne kadar yüksekse, büyütme işlemini o kadar iyi yapacaktır. Bunun nedeni, görüntü genişletildiğinde üzerinde çalışılacak daha fazla ayrıntı ve veri olmasıdır.
Aşağıdaki bölümlerde, WordPress web siteniz için en yaygın resim düzenleme yazılımlarını kullanarak resimleri nasıl yeniden boyutlandıracağınızı göstereceğiz. Tek bir tıklama ile herhangi bir yönteme geçmek için aşağıdaki bağlantıları kullanabilirsiniz:
Hazır mısınız? Hadi başlayalım.
Yöntem 1: GIMP (Ücretsiz) Kullanarak Görüntüleri Büyütme
GIMP, Adobe Photoshop ve Affinity Photo gibi premium araçlara ücretsiz bir alternatiftir. Minimum kalite kaybı ile görüntüleri büyütmek için kullanılabilir. Ancak, sonucun aşağıdaki 3. yöntemde göstereceğimiz Perfect Resize kadar iyi olmayacağı konusunda sizi uyarmalıyız.
Yapmanız gereken ilk şey, ücretsiz yazılımı bilgisayarınıza indirmek ve kurmaktır. Hem Mac hem de Windows cihazlar için kullanılabilir.
Bundan sonra, yeniden boyutlandırmak istediğiniz görüntüyü Gimp’te açmak ve Görüntü ” Görüntüyü Ölçeklendir‘e gitmek isteyeceksiniz.
Görüntülenen açılır pencerede, istediğiniz boyutları ayarlamak için genişlik ve yüksekliği girebilirsiniz.
‘Kalite’ bölümünün altında, enterpolasyon yöntemi olarak ‘Kübik’i seçelim. Bunu yaptıktan sonra, devam edin ve ‘Ölçeklendir’ düğmesine tıklayın.
Hepsi bu kadar; artık büyütülmüş görüntüyü PNG, JPEG, WebP, HTML ve daha fazlası gibi farklı formatlarda dışa aktarabilirsiniz.
Yöntem 2: Irfanview (Ücretsiz) Kullanarak Görüntüleri Büyütme
Irfanview, kullanımı ücretsiz olan kompakt bir fotoğraf düzenleme programıdır. Yalnızca Windows tabanlı işletim sistemlerinde kullanılabilen bu program, görüntüleri yeniden boyutlandırmak ve büyütmek için daha akıllı bir yol sunar.
Bu aracı kullanmaya başlamadan önce, Windows bilgisayarınıza yüklediğinizden emin olalım.
Kurulumdan sonra, resminizi Irfanview’de açın ve Image ” Resize/Resample seçeneğine gidin.
Bu, görüntü yeniden boyutlandırma açılır penceresini getirecektir. Burada, genişlik ve yüksekliği tanımlayarak ‘Yeni boyutu ayarla’ alanına istediğiniz görüntü boyutunu girmeniz gerekecektir.
Bundan sonra, ‘Boyut yöntemi’ bölümü altında yeniden örneklemeyi seçebilirsiniz. Filtre açılır menüsünden ‘Lanczos (en yavaş)’ seçeneğini seçelim.
Son olarak, ‘Yeniden Örneklemeden Sonra Keskinleştirme Uygula’nın yanındaki kutuyu işaretlemek ve işiniz bittiğinde ‘Tamam’ düğmesine tıklamak isteyeceksiniz.
Irfanview şimdi görüntüyü yeniden boyutlandıracak ve daha sonra bilgisayarınıza kaydedebileceksiniz.
Ücretsiz araçların bir görüntüyü daha büyük hale getirmek için yeniden boyutlandırma konusunda çok iyi bir iş çıkarmadığını fark edebilirsiniz. Ancak keskinliği ve kontrastı ayarlayarak görüntüleri büyütebilir ve kalite kaybını en aza indirebilirsiniz.
Bununla birlikte, görüntünün büyütüldüğünde keskin ve net kaldığından emin olmak için Irfanview’in premium aracını da kullanabilirsiniz.
Yöntem 3: ON1 (Premium) Kullanarak Görüntüleri Büyütme
ON1 Resize AI veya daha önce bilinen adıyla Perfect Resize, resimlerinizi akıllıca yeniden boyutlandırmanıza olanak tanıyan bir araçtır.
Yazılım, boyutları büyüdüğünde veya görüntüyü belirli bir alana yakınlaştırmak istediğinizde bile görüntülerinizi yüksek çözünürlükte tutmaya yardımcı olmak için yapay zeka kullanır.
Bağımsız bir yazılım olarak ve Adobe Photoshop, Lightroom, Capture One ve Apple Photos için bir eklenti olarak mevcuttur.
Bağımsız ON1 Resize AL yazılımı 69,99 $ karşılığında temin edilebilir. Bu yazılım, yüksek kaliteyi korurken görüntüleri büyütmek için gelişmiş araçlar sağlar ve fotoğrafçılar ve grafik tasarımcılar için değerli bir yatırımdır.
Umarız bu makale, kaliteden ödün vermeden görselleri nasıl yeniden boyutlandıracağınızı öğrenmenize yardımcı olmuştur. Ayrıca WordPress’te temel resim düzenlemenin nasıl yapılacağına ilişkin kılavuzumuza ve resimleri yönetmek için seçilmiş harika WordPress eklentileri listemize de göz atmak isteyebilirsiniz.

For anyone seeing this in 2022, the gimp solution worked for me. The Sinc(Lanczos3) got replaced by NoHalo. Using this and scaling, I got to resize my png.
I always find quality solution in wpbeginner. Keep up the good work.

Hi, with Gimp is perfect. But if I have lot of photos is there a solution for automate with gimp?
Thanks
Giorgio
WPBeginner Support
Unless I hear otherwise, we don’t have an automation tool to work with Gimp like that at the moment.

Unfortunately the instructions call for opening an image in PS and then selecting File > Automate >Perfect Resize, but there is no Perfect Resize option available. Not sure how an article this new is incorrect, but that what I’m seeing. Very frustrating now since the article encouraged me to spend $60.
WPBeginner Support
There may have been an update to the option location. If you reach out to Perfect Resize’s support they should be able to let you know where the button is currently.

Hello how do you make your mobile Nokia phone photos bigger to download on a shirt
Linto
Thank you so much for this tutorial!!
Liene
Thanks for this post. I haven’t heard about IrfanView, just now downloaded and it really does its job. Great. Thanks.
Melissa
Hi!
I tried the perfect resize which I think is now called ON1, and I wasn’t able to resize from a 3 inch to an 8 inch without losing quality. I just wanted to ask you if you hay any idea why.
Thank you!
manish
i great that i have founded the solution of my big and big problem.
i thank to the programmer of Irfanview and the web site designer.
thank a lot!!!!

I’ve used Perfect Resize software itself without Photoshop and it works better than just resizing with Photoshop without plugin. I did it at school where they had the license for the program. Never tried it in Photoshop with the Resize plugin, good to know! Thanks

plz tell me what is hooks in wordpress? what is work of hooks ..
Safura Abbas
Hi Team,
I am glad to have found my solution on this site. So very well explained and understood. Appreciate your help. I downloaded the trial version of ON1 software and my image that i was trying to enlarge for hours to print right on the paper went in vain until I found your blog. Kudos to Syed Balkhi and team for this informative site. Happy me
Thank you once again.

Hey, I had taken a picture of some old photography but it’s looks worst. How I can increase its quality
Irineu
I have used the extension Simple Image Resizer, Chrome, and have had good results. I’m from Brazil. Congratulations.
Rosie
But it does not make images LARGER – which is the point of the article!
Anthony
This is what i’ve been looking for. PS CC has limited options for retaining image size after merging it with several other layers. Thanks a lot!

I’m using the Gimp resize (logo obtained but company wont resize) and it still is a resolution I cant use?
Dana
Thank you! I have been looking for a resize plug in on photoshop!–Works great!!!!

I have two questions:
1. I know next to nothing about photoshop, but I do use Lightroom 6 when editing images. Is there a way that is similar to the ways mentioned here to do the same in Lightroom?
2. In another article here on WPBeginner, someone commented that the days of lowering the photo resolution for a faster site are practically over. If so, what is the recommended mg size & dpi for most blog photos? (This is a photography blog site, so I want them to be as clear as possible.)
Thanks.
Rebecca Rose
Hi and thank you for your site. I am a rank Beginner (to put it mildly) and found your site while searching the web for information on how to resize photos for Windows Movie Maker.
Right now I want to make Slide Show “movies” for the music I compose … but, those black panels on either side of the smaller photos that I use are a real turn-off! So, I am trying my best to learn what to do … I own Photo Shop – but sadly, as yet I have never used it. After reading the above comments, I think it’s time! Any other comments you have would be VERY welcome …
Richard Cunningham
Here is a simple solution if you are challenged by loss of definition/blurring or over pixellation when you re-size an image. My problem was with a business card where I had an excellent large image in .jpg format but I could not figure out how to retain the definition quality when I reduced it using gimp.
Voila!
Assume that you have an excellent .jpg image which is A4 size and you want to reduce it to a business card size allowing for trim and bleed of 3.6 inches by 2.1 inches at 300 dpi. If you try to edit the file in Gimp, you will end up with unacceptable quality. I wasted hours!
Try this:
1. Open a new file using a 300 dpi template. Set the size parameters as you want them to be – 3.600 x 2.100.
2. Open the file you want to resize – in this case you want to downsize.
3. While in this file, hit Edit – Copy.
4. Go to the new file and hit Edit – Paste.
Check the image details and you will find that you have a perfectly defined reduced 3.6 inch by 2.1 inch image at 300 dpi !

How do you make an image smaller than its original size without losing quality?
And I mean really small. In pixel units “10×10”
The answer to this question will mean a lot to me!
If possible please email me the answer at
Thank you!
Tom
@Eshaan
The thing is, when reducing an image’s size, you have to lose pixels. An image of 100×100 pixels contains 10,000 different pixels, whilst an image of 10×10 only contains 100. This means shrinking a 100×100 image to 10×10 requires you drop 9900 pixels. When making an image larger, you are adding pixels, which is physically possible, unlike in shrinking

Hi I am trying to upload files to you but it is saying that the file size is too small.
How can I fix this so I can forward the pics I like.
joycebartley
hi i am trying to download some pictures from my computer to a contest and they have to be smaller than 4mg unfortunately most of my pictures are a little above that …so how can i reduce the size of mg lower than 4?????? i hope there is an easy way to do it…..from now on should i take the picture with my cell ph up closer or farther away?????
Dan
Whilst this offers some useful techniques, and some expensive ones. I personally don’t think that you should EVER size up an image. EVER!! I have worked in Print for years as well as web and this is just a big no no, or that’s how I was taught.
Size down, never up. This is one technique I will NEVER be taking on board. But thanks for the post.
Dave
I agree with Dan. If you want the picture bigger, you need to get it from the source or retake it.
Joe Turner
Dave, that’s really not very helpful. Obviously, I would think everyone understands they should retake it, if they could. People wouldn’t need to try to look at finding the “best” of all the imperfect ways of resizing if they could just retake a photo. But most of these photos are of events or at times and/or places that can’t be revisited and going back in time is not really an option, so retaking it is usually quite impossible. I think you should realize that most people looking to upsize didn’t think they were going to need to print the photo as large as they are now looking to go, but want the best results given the circumstances they find themselves in.
Mawande
Thanks Joe
I was also shaking my head before your comment. Obviously people would rather do things right the first time, but circumstances and situation can change involuntarily and all people can do is make the best of those situations by coming up with work arounds.
Peggy Woods
I must really spend some time learning how to operate the Photoshop I purchased some time ago. I generally just resize photos by using Picasa3 for cropping and such. Going to g+ this information. Thanks!
Nora
I have only ever used Photshop to re-size images. But only to a certain extent. When you start with a low-rez image it can only be sized up to a certain extent. Open the file in Photshop, click on “image size, un-check “Resample image”, then start adjusting the pixel size under width until you reach as close to 300dpi as possible. You will see the resolution # change as you mess with the pixel size. Once you have gotten to about 300dpi click “save”. The go back and re-check “Resample image”. Click “save” again. Done.
Leon Quinn
Surely there is some way of doing this in Photoshop without a commercial plugin?
Darshan Gajara
This is splendid stuff. Can you please suggest some free Photoshop plugins to simplify photo manipulation?
Mark Narusson
Nice article thanks for sharing. You could also consider using Photoshop, make the image a smart object, enlarge the canvas then scale the image to fit. This isn’t perfect but it has got me out a fix on a few occasions.
Jim Massman
A note for anyone who’s interested in editing pictures: Image formats generally used on the Web are based upon compression algorithms and you can get into trouble easily when editing those formats unless you edit a “lossless” copy. This is an old trick I’ve used for years after seeing some horrible results… simply save the first file in a non-compression file format such as “.tif”; edit that file to your hearts content, then “File Save As” in the .jpg or .png format.
Remember that every time you open, edit, then save a .jpg or .png file, whatever compression settings your graphics editing program has been set to will “recompress” that file. Most programs allow you to determine the compression rate, so it doesn’t hurt to set the default value to the least “loss” setting. The days of ‘needing’ to smash file sizes down for fast page loads are pretty much gone… but you may not know what the program defaults have been set to.

“The days of ‘needing’ to smash file sizes down for fast page loads are pretty much gone…”
That would depend upon your definition of ‘need’, as well as some rudimentary understanding of your target audience.
Is your target audience composed entirely of urban dwellers with access to fast broadband, who only visit your site while at home? Then, *maybe* that’s true.
If, on the other hand, you’re interested in reaching any rural audience at all, then you need to keep in mind that *25%* of the population of the rural US can’t get broad band access, and that 6% of the overall US population doesn’t have broadband access.
If you still say, “Oh, I don’t care about those 16 million potential visitors”, then stop and look at it from the perspective of the mobile web. Does your visitor-base have smart phones? Do you want to support a mobile experience? (A little clue here, your answer should be ‘yes’.) Then guess again. You DO still ‘need’ to do image optimization to minimize the bandwidth requirements for your site.
If you’re a real professional in the business of providing content to users, then *YES* you need to care about the actual user experience for folks visiting your site. And, part of that *IS* still site optimization for speed.
Richard
Guys, there is no way you can enlarge or shrink a pixel. Pixel size is relative. You can only add or subtract pixels.

Very nice and useful tips for resizing images. Specially the ‘Perfect Resize’ Plugin for Photoshop. Resizing of images is a very common day to day activity of bloggers while adding photos to blog posts
Melissa Klotz
I love this site and a lot of your posts have been very helpful. But I’m really scratching my head on this one. Maybe it’s my eyes, maybe my monitor, but I’m seeing very little difference between the “normal resize” and the other resizes. There are plenty of other resampling options in Photoshop. I don’t understand why you would buy a $150 photoshop plugin (extremely expensive for a plugin) or download free software to do something Photoshop is inherently capable of.
