How image compression works
Photos from phones and cameras are often far larger than needed for the web. This tool re-encodes your image at a chosen quality level using your browser's built-in canvas engine:
- JPEG — best for photos; quality 80% typically cuts 60–80% of file size.
- WebP — Google's modern format; ~25% smaller than JPEG at the same quality.
- PNG — lossless; ideal for screenshots, logos and graphics with text.
typical saving = 1 − (compressed ÷ original)
Frequently asked questions
Is my image uploaded to a server?
No. Compression runs 100% in your browser via the canvas API. Nothing is uploaded, stored or seen by anyone.
Will compression reduce image dimensions?
No — only the file size changes. Width and height stay exactly the same. (Need smaller dimensions? Try the Image Resizer.)
Which quality should I choose?
For web photos, 75–85% is visually identical to the original at a fraction of the size. Below 60% you may start seeing artifacts.
