All compression happens entirely inside your browser using the Canvas API. Your images are never sent to any server, never stored, and never seen by anyone but you. Close the tab and everything is gone.

Frequently Asked Questions
No — absolutely not. This tool uses your browser's built-in Canvas API to perform all compression locally on your device. Your image is never sent over the internet, never stored on a server, and never seen by anyone else. You can even use it while offline.
For most use cases, 75–85% quality gives the best balance — images look virtually identical to the original but the file size is dramatically smaller. For web thumbnails or previews, you can go as low as 60%. For print or professional use, stay above 90%.
WebP is generally the winner — it achieves 25–35% smaller file sizes than JPEG at equivalent visual quality, and also supports transparency (like PNG). It is supported by all modern browsers. JPEG is the best choice for maximum compatibility with older software. PNG is lossless and ideal for graphics or screenshots that need sharp edges.
PNG is a lossless format, so the quality slider has no effect on PNG output — every pixel is preserved perfectly. The compression for PNG works by optimizing the internal encoding, but the visual data remains identical. If you want lossy compression of a PNG, convert it to JPEG or WebP format.
The tool supports images up to 50 MB. Very large images (over 20 MP) may take a moment to process as they need to be drawn onto a canvas in your browser. For best performance on large files, use the "Max Width" option to resize at the same time as compressing.
Done!
