Compress

Reduce file size, keep quality

Compress an image for a thumbnail

Thumbnails should be tiny — 50 KB or less — so they load instantly in lists, grids, and previews. Combined with resizing to a small pixel size (e.g. 200 × 200), this is easy to achieve.

Frequently asked questions

Are my images uploaded anywhere?

No. Compression runs entirely in your browser. Your files never leave your device.

What format should I use?

JPG for photos (smallest files for natural images). PNG for screenshots, logos, or graphics with transparency. WebP if the destination accepts it (smallest files overall).
