Frequently asked questions

Is the photo orientation kept?

Yes. Photos are turned the right way up before compressing, so they look correct everywhere.

Is the camera information (EXIF) kept?

No. Location, camera and other metadata are removed, which saves space and protects your privacy.

Should I convert to WebP or AVIF instead?

For websites, WebP and AVIF are usually smaller still. Pick them under Output format. For sharing and printing, JPEG is the most compatible.

Are my files uploaded?

Your files stay on your device. Conversion runs inside your own web browser, so your files are never uploaded to our servers or anyone else’s. Nobody can see them, and nothing is stored after you close the tab.

Is it free?

Yes, it’s completely free. There’s no sign-up, no watermark and no limit on how many files you convert. Each file can be up to 1 GB.
