Your files stay on the thread.
filum is Latin for thread. Every tool runs inside your browser — your document is read, worked on, and handed back without ever leaving your device. Held on the line. Never sent.
Everything you do to a document.
22 tools, each running entirely in your browser — so the work is private by default, not by promise.
The only document tool that can't see your files.
Other converters upload your document, then ask you to trust a deletion promise. Filum removes the need for trust — there is nothing on the other end.
Every tool executes in this browser tab. The file is read from disk, worked on, and saved back — it never travels to a server, so it can't be intercepted or logged.
There is no copy on a server to leak, sell, or forget to delete. Close the tab and nothing of your file remains anywhere but your own machine.
No upload-and-download round-trip — the work starts instantly and finishes at the speed of your device, not your connection. No account, no email.
Your documents, kept to yourself.
Open a file and watch the work happen — without a single byte leaving your device.
