Your files are safe here
Your files never leave your device
Every tool runs inside your own browser tab. There is no upload step, so there is nothing for us, or anyone else, to see.
Nothing is stored, nothing to delete
We do not keep copies. Close or refresh the tab and your files are gone from memory.
Fake and unsafe files are blocked
Each file is checked by its real contents, not its name. Executables, scripts, SVG files and renamed files are rejected.
Locked-down pages
Strict browser security headers stop the page from sending data to other websites. PDFs are only read, never run.
