How to use the image compressor
Upload JPEG, PNG, or WebP images and adjust the quality to reduce file size. It helps speed up websites, meet email attachment limits, and save storage. You can watch the before/after size while balancing quality.
Compression runs entirely in your browser (Canvas), so photos are never uploaded to a server. You can process several images at once while keeping your privacy.
Frequently asked questions

- No. Compression happens inside your browser and images are never transmitted, so personal photos are safe.
- How much quality is lost?
- You control it with the quality slider. For typical photos, 70–80% quality keeps the look while greatly reducing size.
- Which formats are supported?
- Major formats such as JPEG, PNG, and WebP are supported, and you can choose the output format.
