How to compress an image
- Upload your image — drop a JPG, PNG or WebP, or click to browse.
- Choose a quality and format. Lower quality means a smaller file.
- Compress, check the size saving, then download.
Getting the smallest file
For photos, WebP at 70–80% quality is the sweet spot — a big size cut with no visible difference. JPG is the universal fallback. Reach for PNG only when you need a transparent background or crisp flat graphics, and remember that resizing to the dimensions you actually display saves even more than re-encoding alone.
Frequently asked questions
How does the compression work?
Your image is decoded and re-encoded at the quality level you pick using the browser's own canvas. For JPG and WebP, lowering quality discards visual detail you won't notice to make the file much smaller. PNG is re-encoded losslessly.
Which format should I export?
WebP usually gives the smallest file at the same quality and is supported everywhere modern. JPG is the safest universal choice for photos. Keep PNG only when you need transparency or pixel-perfect graphics.
Will it reduce the dimensions?
No — the compressor keeps the original width and height and only changes the encoding quality. If you also want fewer pixels, use the Image Resizer first.
Are my images uploaded?
No. Everything runs locally in your browser. Nothing you open is ever sent to a server.
