    Hi. I recently got an API key for EWWW Image Optimizer Cloud and I’m happy with it so far. I originally got the $1 plan to try it out, but am considering getting a higher plan.

    I have a few questions:

    1. How do I go about upgrading to a plan for the volume that I will use ongoing? Will I be assigned a new key and I just discard the old key and not use it (since it’s only $1) and just apply for a higher plan? Or will my existing key be upgraded? Do I have to wait until the end of the month, or can I do it in between?
    2. I am planning to optimize the other images in my library. Is there a package where I can get an API key for all existing images in my library and then downgrade to a plan that I will use from thereon out? I expect an initial surge in my need for optimization, but it will die down once I optimize everything and I just need to do my ongoing image optimization.
    3. Where are the original images stored? Is there a way for me to restore them, either automatically or through the plugin in case something goes wrong, or do I have to do them manually?

    Lots of good questions:

    1. When you sign up for a higher plan, the quota on your existing key is increased. You can do it at any time, the service does all quota adjustments as each subscription renews (or ends). So you can also cancel the higher plan at any time during the month, and your quota will remain the same for an entire month from the date of purchase.

    2. I think I already answered that, but let me know if you still have questions regarding that.

    3. Only converted images have their originals kept in place, because they get new file extensions. Optimized images are done in place, overwriting the originals, so it is up to you to do a backup beforehand. Many webhosts do automatic backups, which gives you an extra layer of protection, but I would do a backup yourself just to be safe. I don’t think I’ve seen the plugin destroy an image for almost 2 years (the jpg optimization was not working on a couple hosts, and the originals were getting overwritten by a blank file, but I quickly implemented a fail-safe for that), but you never know…

    Got it. So based on the plugin, I have the following stats for my main blog.

    18312 images in the Media Library have been selected (18004 unoptimized), with 54573 resizes (54089 unoptimized).

    So I’m planning to upgrade to a Platinum plan for a month (100,000 images) then run Bulk Optimize for all the images. Since I have some left over I’ll also optimize my other blogs. Then I’ll downgrade my plan to what I will use ongoing (I think it’ll be Bronze or Silver based on my needs) then I’ll keep my remaining quota, and then use the new plan after a month and ongoing.

    Makes sense to do backups since my host does one daily and I can trigger it on my own too. I remember encountering problems with discolored JPGs in a really old version but this latest version doesn’t change anything based on my random tests. Planning to just use JPG for Bulk Optimize since some PNGs change color when optimized (do you know why this is if it’s lossless?), and I have to manually change links for GIF to PNG.

    PNGs shouldn’t change color when optimized. If you find any that do, let me know, because that would be a bug.

    So I signed up for a $20 plan to optimize everything in the library. What I did was to cancel the recurring payment for the $1 plan, and then will cancel the recurring payment for the $20 plan as well. Come the time we need to renew I’ll sign up for a new ongoing plan.

    Here’s the original unoptimized PNG file:

    Here’s the optimized PNG file that changed colors:
    https://1t6wye3jlnwu2620nk2myd4818ou.wpengine.netdna-cdn.com/wp-content/uploads/2014/05/teambenitez125s1.png

    You can also download the original file from our site and try uploading and optimizing it yourself.

    Can you help check what might be going wrong with the optimization for this one?

    Thanks!

    Hi nosilver4u. I saw that this was marked resolved already but there is one open item–were you able to check the PNG that changed color and was a fix already implemented? Thanks!

    Sorry about that, I missed your followup post somehow. I will look into it soon.

    And just need to confirm also that you do NOT have the lossy optimization setting turned on, correct?

    That’s correct, lossy optimization is NOT turned on. Thanks!

    This took a while to figure out, but it is related to the embedded color profile that is being used (GIMP says it is an Adobe profile). If I download the images and view them on linux, I see no difference because the color profile is being ignored by the linux image viewer. If I open the original image in the GIMP, and tell it to convert the image to sRGB built-in, THEN the images show up differently in the linux image viewer. If I optimize the sRGB version of the image, there is no color change from the original that you’ve posted.

    So, definitively, optipng and pngout both strip the embedded color profile. On that particular image, it is costing you about 30% of the file size. Convert it to a built-in color profile (sRGB), and everything should be happy. I don’t know if that fits with your workflow, but it is definitely worth considering.

    Ok, so what I did was to change the color profile to sRGB, saved the image, and then uploaded and optimized it in EWWW Image Optimizer Cloud. Color looks the same, so I think the fix works.

    No issues with the workflow since this should only happen for a few images (this is the only one I’ve encountered so far). So I will just keep in mind that if a PNG changes color it’s probably because of the color profile. Thanks!
