How this tool works
JPEG, PNG, and WebP images are recompressed locally in your browser while keeping their original dimensions and format.
- Choose one or more JPEG, PNG, or WebP images.
- Choose an output quality.
- Process the queue and compare the original and result sizes.
Processing stays inside a disposable browser worker. Canceling or leaving the page terminates that worker and releases its memory.
Capabilities and limits
- Files per job
- 1–50
- Per-file limit
- 50 MB
- Privacy mode
- LOCAL ONLY
- Compression is not guaranteed to make every file smaller.
- PNG uses browser-native re-encoding rather than an advanced optimizer; the original is retained when re-encoding is not smaller.
- Images above 40 megapixels are rejected and no server fallback is used.
