Frequently Asked Questions

Will compression reduce image quality visibly?

At moderate settings (70–85% quality) the difference is virtually invisible to the eye, while file size often drops 50–80%. You can preview the result before downloading.

Are my photos uploaded to a server?

No. The compression runs entirely in your browser using the Canvas API. Your images never leave your device.

Which format should I choose for the web?

WebP usually gives the smallest files with the best quality, followed by JPEG for photos and PNG for graphics with transparency.

Can I compress many images at once?

Yes — drop an entire folder's worth of images and compress them in one batch, then download them all.
