   image compression plugin is a must for having blazing fast websites.
   most of the website slow speed is caused by having heavy images on that.
   I have used image optimizer and lately I was anxious about its usage.
   But after my confusion about plugin and its role in website performance, I am optimistic about using it.

   Can you please explain why you recommend EWWW, considering that it performs so poorly compared to the others in your PNG compression test? Thanks.

     Our recommendation was based on the JPEG as that is what most users tend to add to their site instead of PNGs

   Nice article but is there a way to delete the original unoptimized image ? because you’ll use the optime one in its place

   is there a way? a hook , something?

   thanks

     Depending on the plugin you use there is an option to remove the original image in the plugin’s settings.

   Personally I am using ShortPixel.
   I have one question:
   can I use two of them in the same website?
   thank you for the very useful article!

   • WPBeginner Support

     We would not recommend more than one image compression plugin on the same site to prevent certain compression issues.

   I’m torn between getting the Shortpixel plugin or just continue to use the Shortpixel website tool. (One less plugin). Are there extra advantages to having the plugin? All my photos to date were already optimized with the Ewww Image Optimizer (which I have now deleted).

     Unless we hear otherwise, the benefit of using the plugin mainly means that you would not go to their site to optimize your images.

   thank you for the very useful article! I have one question:

   If I optimize the images before upload, do I need then any image optimization plugin?

   返信

   • WPBeginner Support

     If you already optimize the image, you do not need to worry about adding a plugin to help you optimize them again.

   Hello ,

   Thanx for the article and share.
   I do have a question about this if I used a compression plugin and used another one on the same website.
   How will this affect the image?

   Will this be a compression on a compression if I used another plugin>?

   Thanxx

   返信

   • WPBeginner Support

     Yes, it would likely cause that issue, we would recommend keeping the compression to a single plugin for the time being.

   Great article to date compared to other content out there. I think my best is shortpixel.
   Do you still think it is among the top five this month?

    I sell prints on Storefront. They all have white backgrounds. An image (eg a car) takes less than half the page space and is surrounded by white. The white surround (requiring zero resolution) adds to size but shows depth and space for mounting and framing. If I crop the white space a buyer will not see the print in context. How can one manage this conflict between large areas of “dead” space that serve a purpose and the reduction of image sizes for uploading to Wordpress?

    返信

    • WPBeginner Support

      The image compression plugins should not remove the white space that you say is required, they would only reduce the size of the data that makes up the images.

    reSmushit hasn’t been updated in 10 months and its support forum is filled with unresolved tickets saying it doesn’t work any more. Looks abandoned unfortunately.

    返信

    • WPBeginner Support

      Thank you for reaching out, it appears the plugin was recently updated and they are replying to tickets. The plugin does not appear to be abandoned.

    Hi,
    Thanks for the info, it was very useful.
    I needed compression because my blog had ground to a halt, and support told me mo optimise ‘image and js files’.
    Do you have a suggestion for the latter too?
    Thanks for your help,
    Owen

    • WPBeginner Support

      You would likely need to reach out to the support for the plugin that has the JS file that is giving you trouble but for some tips, you may want to take a look at our article here: https://www.wpbeginner.com/wordpress-performance-speed/

        Thanks for replying.
        I absolutely no idea which js file is causing problems, or even whether any are at all.
        That is beyond my current ability

    If I were to try a few of the different free plugins will each re-optimize the images? This is for a photo website, images already optimized using Photoshop “Save for Web” feature. I use the NextGen Pro plugin. When I run a test on GTMetrix I keep seeing a note to optimize my images. I’ve tried EWWW Image Optimizer, Smush and Imagify.

    My concern is that trying these different plugins keeps optimizing the images over and over. Do each of the plugins store their own version of the optimized original?

    Thanks for the article and any comment!

    返信

    • WPBeginner Support

      It would depend on the plugin for how they handle the original but you are correct. If you are using an image optimization plugin, you would only want to use one to prevent multiple types of compression on an image.

    I would be interresting to see the WordPress default compression results in your comparison list. At my knowledge, WordPress use jpeg compression at 80% or something, but does not recompress the various thumbnails sizes so it slows down the admin dashboard a bit. For best visual results, I already tried Photoshop manual compression and disabled the WordPress compression. Because even if you work hard to display the perfect image with Photoshop, WordPress will recompress it in the upload process.

    返信

    I don’t understand how these percentages can be meaningful without evaluating the quality of the resulting product. I can reduce images by 20-80% in Photoshop by changing the JPEG quality, but at some point they degrade and below that they look awful. Did you compare the quality of the results, looking for artifacts, color changes, perceived sharpness?

    Thanks,
    Donna

    返信

      Hi Donna,

      All these plugins attempt to compress images without quality loss. They keep their settings lower to ensure minimal quality loss. However, when you do the same thing in Photoshop you can compress more to the point where quality is acceptable to you.

    I prefer Imsanity.
    Not only can you set the images to various levels of compression, but it will also resize huge images to more manageable sizes for web.

    I’d like to point out that the PNG compression by ReSmush.it is NOT lossless. I checked their API and while JPGs can be lossless, PNG compression is NOT. Article needs to be updated to reflect that.

    In addition, ReSmush.it’s interface is vague in compression options because the only thing you can set is image quality value, which is default at 92. There’s no way to tell if that means lossless compression or not. I checked their site again and they indicate anything below 90 will result in loss of value, so I’m ASSUMING then that an image quality value of 90+ will be lossless.

    BUT because they didn’t explain it clearly and because there’s no option to use lossless PNG compression, I’ve had to look for another plugin solution.

      ANDRZEJ, I’m not sure if you’re using the free or premium one here. If using the pro you would see savings of around 47.4% on the first image and on the full image it’s 55.5%.

      http://take.ms/IVUBa

      On the second image, it’s 78.6% for the full one and overall with thumbs it’s 72.3%.

      http://take.ms/WpgS0

      One last thing to mention is that we’re close to releasing a new version that will offer further improvements to your image optimisation percentages and get your site loading even quicker.

      Just wanted to throw this out.
