 * Would be better if offered the ability set a maximum file size instead of by 
   percentage. This would recognise that your original images wont always be the
   same source/size, and allows you to define a uniform maximum file size of images.
   
   Would be great to use this tool on images already in the media folder as well.
   Unfortunately not working when uploading images using WP All Import (hence suggestion
   above)

 * Thank you for your feedback! I’ll clarify a few important points about how QuickWebP
   works: 1. Compression quality ≠ Maximum file size
 * Your request for a “maximum file size” instead of a percentage shows a misunderstanding
   of how image compression works.
 * What QuickWebP currently does — like all image compression tools:
 * The “Quality” setting, currently 0–100%, default 75%, controls the compression
   level applied to the image.
 * The lower the quality, the more the image is compressed, and the smaller the 
   file becomes.
 * It is a compression algorithm, not a file size limit.
 * Why a “maximum file size” cannot be reliably defined:
 * The final size of a compressed image depends on its visual complexity — colors,
   details, contrast — not only on its dimensions.
 * A 1000×1000px photo with a lot of details can be heavier than a very simple 2000
   ×2000px image, even with the same quality setting.
 * Concrete example:
    - Complex photo, landscape, 1000×1000px at 75% quality → 250 KB
    - Simple logo, 2000×2000px at 75% quality → 80 KB
 * If you set “maximum size = 150 KB”, the logo would be perfectly fine, but the
   photo would need to be over-compressed and could become unreadable.
 * The right approach — the one used by QuickWebP:
 * Setting a consistent quality level, for example 75%, ensures that all your images
   keep the same visual quality level.
 * Each image will have a different file size depending on its complexity, but all
   of them will remain visually optimized.
 * You can adjust the global quality depending on your needs:
    - 70% for stronger compression
    - 85% for higher quality
 * Also, QuickWebP already provides a setting to resize images using a maximum width
   in pixels, which is the proper way to help control file sizes. 2. Bulk optimization:
   already available!
 * QuickWebP already includes a Bulk Optimization feature, available in the plugin
   settings. This feature allows you to optimize all existing images in your media
   library.
 * Please check the **Bulk Optimization** section in your QuickWebP settings:
 * **Media → QuickWebP** 3. WP All Import: technical limitation
 * QuickWebP integrates with standard WordPress hooks during image upload, such 
   as `wp_handle_upload_prefilter`.
 * If WP All Import bypasses these native WordPress hooks, which is likely for performance
   reasons, QuickWebP cannot intercept those images.
