How it works — and why it is private
- 1
Choose a file
Drop, paste or pick files from your phone or computer. The real file type is checked, not just the extension.
- 2
Processed on your device
Your browser does the work with its built-in image and Web Worker features. Nothing is sent to a server.
- 3
Download the result
Save each file or everything as a ZIP. Close the tab and nothing is left behind.
