HEIF
High Efficiency Image Format: HEVC-compressed photos at about half the size of JPG.
AVIF
AV1-based image format that is much smaller than JPG at the same quality, with HDR and transparency.
Images are converted with ImageMagick running inside your browser. Colour profiles, transparency and EXIF orientation are respected; when the target format has no transparency, transparent areas become white. Open Options to set quality, size or remove metadata.
