Your files are never uploaded. Anywhere.
Not to a server of ours, not to a third party, never. When you pick a file it stays in your browser’s memory: it is read, processed and written back on your device, and you save the result yourself. There is no path that takes it elsewhere, because there is no server to send it to.
- Processed locallyFormats are handled by WebAssembly code running in your browser, not by a remote service.
- Nothing to upload, nothing to wait forOther services send your file to a server and then send it back to you. Here the file never leaves: there is no upload to wait for.
- No accountNo sign-up, no email, no daily limits to get around by paying.
- No files to deleteOthers promise to erase your files after an hour. We have nothing to erase: they never reached us.
