Files are processed in your browser. Nothing is uploaded to a server.
Large images slow down pages and fill up inboxes. Compression reduces file size by lowering quality just enough that the eye barely notices, which is exactly what you want for the web, email attachments and faster uploads.
This compressor lets you dial in a quality level and immediately see the resulting file size before you download.
How to compress an image
- Upload the image you want to make smaller.
- Drag the quality slider and watch the estimated size update live.
- Optionally cap the maximum width to shrink huge photos further.
- Click Compress and download the optimized file.
Typical savings
| Quality setting | Visual impact | Typical size cut |
|---|---|---|
| 90% | Indistinguishable | 20–40% |
| 75% | Very subtle softening | 40–60% |
| 50% | Noticeable on close inspection | 60–80% |
Actual results depend on the image; photos with lots of detail compress less than flat graphics.
Why this compressor
- Live size estimate so you compress to a target, not by guesswork.

Frequently asked questions
What quality should I pick for the web?
Around 75–80% is the sweet spot for most photos: a big size reduction with little visible difference.
Can I compress PNG screenshots?
Yes, though PNG is lossless; converting to WebP or JPG usually saves much more on screenshots with photographic content.
Does compressing repeatedly degrade the image?
Each lossy pass can add artifacts. Compress once from the original rather than re-compressing an already-compressed file.
