Help
- Drop JPG, PNG or WebP files: each format gets its own method (quality for JPG and WebP, palette reduction or re-encoding for PNG).
- A live estimate on the first file shows the before/after size and a comparison slider: tune until you are happy.
- “Aim for a maximum size” adjusts the quality automatically (then the dimensions if needed) to fit under the size you want, say 200 KB.
- A file that is already well optimized is returned as is: the tool never makes it heavier.
- Metadata (GPS position, camera model) is removed from recompressed images.

Frequently asked questions
Are my images uploaded to a server?
No. Compression runs in your browser; no file leaves your device.
Which quality should I use for the web?
Around 75% for a JPG or WebP: the size drops sharply with no visible difference. Use the comparison slider to check on your own image.
Is the compression lossless?
JPG and WebP are recompressed with a slight, adjustable loss. For a PNG you choose: reduced palette (lossy, very effective) or strictly identical re-encoding.
