Supported formats
Common formats open right away. Formats such as HEIC and AVIF download a processing file (about 15MB) on first use. Your browser keeps it so it can load faster next time. Animated GIFs and multi-image files use the first frame or page only.
Up to 25MB per photo, 20 photos, 100MB each for inputs and results, 8,192px per side and 16 megapixels. Extra output formats don't copy date, camera or location details. Support depends on the file; damaged or encrypted files may not open.
