Why on-device

Split, sign, rotate, and organize — without leaving your browser.

Most PDF tools route every operation through a server — even splitting and rotating, which require no server at all. Filum runs those in your browser. Format conversion (Word, Excel, EPUB) uses a secure server that deletes your file the moment it's done.

On-device where possible

Organize, split, merge, sign, rotate, and watermark PDFs entirely in your browser — your file never reaches a server. Format conversion (Word, Excel, EPUB, and more) uses a secure server process that deletes the file the moment it's done.

Nothing is stored

No account means no profile. No permanent storage means no database entry to leak, sell, or request a deletion of. Closed tab, gone file — on-device tools leave no trace anywhere; server-side tools delete within seconds.

No account, ever

No sign-up, no email, no subscription prompt before you can use a tool. Every tool — on-device and server-side — is available immediately, without any form of registration.

The toolkit

Everything you do to a document.

28 tools — most running entirely in your browser, format conversion using a secure server that deletes within 60 minutes. Private by design, not by promise.

Your documents, kept to yourself.

Drop a file. Watch the work happen. On-device for most tools — encrypted, deleted-on-done for the rest.
