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 every tool in your browser instead. Your file never leaves your device, so there is nothing to upload, store, or delete.
Every tool — organize, split, merge, sign, rotate, watermark, compress, and convert — runs entirely in your browser. Your file never reaches a server, because there is no server in the path. Nothing is uploaded, ever.
No account means no profile. No upload means no database entry to leak, sell, or request a deletion of. Closed tab, gone file — the tools leave no trace anywhere, because your file never left your device.
No sign-up, no email, no subscription prompt before you can use a tool. Every tool is available immediately, without any form of registration.
Everything you do to a document.
46 tools — every one runs entirely in your browser. Your file never leaves your device. Private by design, not by promise.
Your documents, kept to yourself.
Drop a file. Watch the work happen. On-device for every tool — nothing uploaded, nothing to delete.
