How it works
A useful result,
without the upload.
Compress JPEG and WebP images locally with a live quality setting, size comparison and instant download. The file is decoded and processed inside this browser tab, so File Preflight never receives its contents.
LOCAL METHODDecode locally → re-encode at selected quality
Worked example
A high-quality camera JPEG can often be made substantially smaller at 80–85% quality for online use.
Before you send the file
- Results depend on image detail, noise and the original encoding.
- Use PNG for graphics that require transparency or crisp flat-color edges.
- Keep an untouched original before compressing production artwork.
