Images not uploading? Make sure you're selecting supported image types: JPG, PNG, or WebP.
Can't see the compressed preview? If the image appears broken or doesn't update, try reloading the page or using a different browser.
Files aren't downloading? Some browsers or privacy extensions may block downloads. Try disabling extensions or switching browsers.
Compression doesn't seem to change file size? Some images, especially already-compressed JPGs, may not shrink much more. Try increasing the compression level.
