How to use it
- Pick a quality level. 75% is a good balance for most photos.
- Optionally set a maximum width to shrink very large photos.

About this tool
Large images slow down websites, fill up email attachments and get rejected by upload forms. Compressing them can cut their size by 60 to 90 percent with little or no visible difference.
This compressor re-encodes your images using your browser's built-in JPG and WebP encoders. Lowering the quality removes detail your eye is unlikely to notice. Setting a maximum width also helps a lot, because phone cameras often take photos far larger than any screen can show.
If you need a file under a specific size for a form, use one of the fixed-size tools such as compress to 50KB or compress to 100KB.
Questions
What quality should I choose?
For websites and sharing, 70 to 80 percent is ideal. For printing, use 85 percent or higher.
JPG or WebP?
WebP files are usually 25 to 35 percent smaller than JPG at the same quality. Choose JPG if you are not sure the place you are uploading to accepts WebP.
Are my files uploaded to a server?
No. The tool runs entirely in your web browser using JavaScript. Your files are read and processed on your own device and are never sent to us or anyone else. You can even disconnect from the internet after the page loads and it will still work.
