Are my images uploaded to a server?

No. All compression happens in your browser using WebAssembly. Your images never leave your device.

What image formats are supported?

JPG, PNG, and WebP formats are supported. The compressed output maintains the same format as the original.

How much can I reduce the file size?

Typical reductions range from 40–80% depending on the image content and chosen quality level. Photos with lots of detail compress more.

Does compression affect image quality?

At higher quality settings, the difference is nearly imperceptible. You can adjust the quality slider to find the best balance for your needs.

Can I compress multiple images at once?

Yes, upload several images and each will be compressed independently with the same quality settings. Download them all at once.

Does this work on my phone or tablet?

Yes. The tool runs entirely in your browser, so it works on any device — including smartphones and tablets — with no app to install.

What quality setting gives the best balance?

For web use, 70-80% quality reduces file size by 60-80% with minimal visible difference. For print, use 90%+ to preserve fine detail.

Does compression preserve EXIF metadata?

EXIF metadata such as camera info, GPS, and date is stripped during compression, which helps reduce file size and protects your privacy.
