Compress Image
Smaller files, quality you control, results you see instantly.
How to compress an image
- Add an image; it is compressed immediately at the current quality and the size comparison appears.
- Move the quality slider to trade size against fidelity; the result recompresses live so you see the effect at once.
- WebP usually lands 25 to 35 percent smaller than JPG at the same visual quality; pick JPG when the file must open everywhere.
- Hover the preview and click the eye to inspect the compressed image full-size before downloading.
Frequently asked questions
- What quality setting should I use?
- 80 is the sweet spot for photos: large savings with no visible difference at normal viewing. Go to 60-70 for email attachments, stay at 90+ when the image will be edited again.
- Why did my PNG get so much smaller?
- PNG stores photos losslessly and therefore hugely; re-encoding as JPG or WebP applies photographic compression. For graphics with sharp edges and few colors, PNG can actually be the smaller choice.
- Does compressing change the image dimensions?
- No, width and height stay identical; only the encoding changes. To also shrink dimensions, use the resize tool first, which saves even more.
- Is my image uploaded anywhere?
- No. Compression runs entirely in your browser; the image never leaves your device.
