What is Vellum

A paper workshop for PDFs

Vellum is a free collection of online PDF utilities — merging, splitting, compressing, converting, editing, signing and protecting documents — built to feel like a well-kept print shop: familiar tools, honest work, no surprises.

Why use it

Private by design

Unlike most online PDF services, Vellum never ships your document to a server. Every byte is processed in your browser with open libraries, so contracts, scans and ID papers stay exactly where they belong.

How to use

Three moves, done

01 — Pick a tool above. 02 — Drop your file on the workbench. 03 — Tune the options, download the result. No queue, no upload bar — the moment you drop the file is the moment work begins.

Questions, answered

Is Vellum really free?

Yes — every tool is free and unlimited. There are no accounts, no watermarks on output and no hidden quotas.

Are my files uploaded anywhere?

No. All processing runs locally in your browser using client-side libraries. You can even go offline mid-session on most tools.

Which file types can I work with?

PDFs in and out, plus JPG/PNG images for image-to-PDF, DOCX for Word conversion, and plain-text export.

Does it work on my phone?

Vellum is built mobile-first. Signing with a fingertip on a phone works just as well as a mouse on a desktop.
