Quality, compatibility and file limits
Choose dimensions and image quality before converting. Still-image exports keep one frame. Unedited GIF, WebP, AVIF, JPEG XL and MNG conversions can retain animation. Animated edits use a GIF intermediate with a limited color palette. Canvas editing uses browser display precision and does not preserve original EXIF, HDR, or scientific image data.
