Yes. It overwrites the original file and all generated thumbnail sizes with the compressed versions. Make a backup before running bulk compression<\/strong> if you want to preserve originals.<\/p><\/dd>\nWhat image formats are supported?<\/h3><\/dt>\nJPEG, PNG, WebP, and GIF. Unsupported formats (SVG, RAW, etc.) are skipped automatically.<\/p><\/dd>\n
Does it work with my existing media library?<\/h3><\/dt>\nYes. Go to Media \u2192 PuffPix<\/strong> to bulk-compress all unoptimized images. The plugin tracks which images have already been compressed and skips them on re-runs.<\/p><\/dd>\nWhat is the difference between Standard, Pro, and Max engines?<\/h3><\/dt>\nStandard (GD)<\/strong> uses PHP's built-in GD library \u2014 fast and available everywhere, good for most use cases. Pro<\/strong> uses mozjpeg (JPEG) and pngquant (PNG) \u2014 these produce noticeably smaller files at the same visual quality compared to GD. Max<\/strong> applies the most aggressive settings available. Pro and Max require a paid plan or trial.<\/p><\/dd>\nCan I compress only certain images?<\/h3><\/dt>\nYes. You can compress individual images from the media library by clicking the Compress<\/strong> button in the PuffPix column. Auto-compress on upload can also be disabled in settings.<\/p><\/dd>\nWhat happens if compression doesn't reduce the file size?<\/h3><\/dt>\nIf the compressed version is not smaller than the original (e.g. the image was already optimized), the plugin keeps the original file unchanged.<\/p><\/dd>\n
Does it slow down my uploads?<\/h3><\/dt>\nSlightly \u2014 the plugin makes an API call during upload which adds a few seconds. This only affects the upload process, not your visitors.<\/p><\/dd>\n
Is it compatible with WooCommerce product images?<\/h3><\/dt>\nYes. Product images uploaded through WooCommerce go through the standard WordPress media upload flow and are compressed automatically.<\/p><\/dd>\n
Is it compatible with page builders like Elementor or Divi?<\/h3><\/dt>\nYes. Any image uploaded via the WordPress media library is compressed, regardless of which plugin or theme triggers the upload.<\/p><\/dd>\n
What happens if the API is unavailable?<\/h3><\/dt>\nIf the PuffPix API is unreachable, the upload completes normally with the original uncompressed file. No images are lost.<\/p><\/dd>\n
Can I retry failed compressions?<\/h3><\/dt>\nYes. Images that failed compression show a Retry<\/strong> link in the media library column. You can also re-run bulk compression \u2014 already-compressed images are skipped.<\/p><\/dd>\n\n<\/dl>\n\n\n1.2.20<\/h4>\n\n\n- Security: pin API download URL to puffpix.com domain<\/li>\n
