Usage notes
Inputs and results are processed on this device. Tool content is not sent to a processing server.
Limits: 20 MiB per file, 50 MiB combined inputs, 16 million pixels, 8,192 pixels per side, 80 MiB combined outputs and 20 seconds per image. Animated files are rejected.
JPEG output uses the chosen background for transparency. Browser encoder support is checked; unsupported formats are never silently relabeled.
Processing re-encodes pixels, which can change color profiles and omit source metadata. Metadata inspection reports available fields locally. Compression is not guaranteed to make every file smaller.
