Images, just right.
Re-encode JPEG, PNG, WebP, GIF, BMP and HEIC files at the size and quality you choose. Common metadata is removed in the process.
HEIC and HEIF files can be selected as they are. The converter is prepared automatically and your photos are never sent.
Only the main still image is converted. Live Photo videos, burst frames and depth data are not kept. HDR and wide-gamut colour or brightness may shift. HEIC files are limited to 20 MB and about 12.6 megapixels each (24 MP and 48 MP photos are not supported).
