Image Compressor
Make image files smaller for faster websites. Free, no sign-up, files never leave your device.
What it does
Pick an image, drag the quality slider, and choose an output format. The tool recompresses the image with the HTML canvas API and shows the before and after file sizes, so you can find the sweet spot between quality and size.
Tips
WebP usually gives the smallest files at the same visual quality. For photos, JPEG at 70 to 80 percent is a good default. PNG is lossless, so the slider has no effect on it, but converting PNG photos to WebP often cuts size dramatically.
Private by design
Your images never leave your device. Compression happens locally with canvas, no server involved.

Frequently asked questions
Will compressing reduce image dimensions?
No, this tool only reduces file size. The width and height stay the same. Use the Image Resizer tool if you need smaller dimensions.
Which format should I choose?
WebP for the smallest files on modern sites, JPEG for maximum compatibility, PNG when you need transparency or pixel-perfect graphics.
Are my photos uploaded anywhere?
No. Everything happens in your browser, so your files never leave your device.
