FAQ
Questions
Are my photos uploaded anywhere?
No. The page reads your file in this browser tab and does the work on your device. Nothing is sent to a server, and closing the tab clears it. You can switch on airplane mode after the page loads and the tool still works.
Is the full-resolution photo saved?
Yes. The preview is scaled for speed, but the saved file is processed at the original size.
Is location data kept?
No. The saved photo is a new file without EXIF, GPS or camera data.
