How it works

Your document goes in. Nothing else comes out.

Every operation happens inside your machine's perimeter. Watch a file move through VellumDoc — it never crosses the line.

01

Drop it in

Open any PDF, Word, Excel or PowerPoint file — or a whole folder — straight from your disk. Nothing uploads.

● stays local

02

It works on-device

Optimise, convert, redact or sign — the engines run on your own processor, reporting real progress as they go.

● no round-trip

03

Verified, not trusted

Redactions are checked to be truly gone; conversions are validated against the original. You see proof, not a promise.

● checked output

04

Yours, and only yours

The finished file lands beside your original. No copy on a server, because there was never a server in the loop.

● zero exposure

The difference

Your files never leave the room.

Adobe, Foxit and the rest quietly route your documents through their servers. For a contract, a tender, or a case file, that's a risk you can't sign off on.

Every optimise, convert, redact and sign happens entirely on-device. No upload. No round-trip. No exception.

It isn't a setting you switch on — it's the architecture. VellumDoc has no network code for document handling at all, which is exactly what a security reviewer wants to hear.

Cloud PDF tools

Your document is uploaded, processed on their server, downloaded back.

file → their cloud → back

VellumDoc

Your document is read, processed and written — all inside your machine.

file → your Mac → done

What a security reviewer sees

VellumDoc performs no network communication for document processing or licensing. No content, usage data or telemetry is transmitted at any time. Air-gapped deployment is fully supported.

The workbench

Everything you open Acrobat for — and the things it can't do.

One fast, uncluttered app that replaces a stack of subscriptions. Move your cursor across a card.

Flagship

90% smaller

Document optimisation

Shrink PDF, Word, Excel and PowerPoint dramatically — while every formula, layout, chart and signature is preserved exactly. Maximum, Balanced, Aggressive, or hit a target size. Not compression that degrades. Optimisation that keeps it intact.

Pixel-faithful conversion

PDF to Word, PowerPoint and Excel that matches the original — colour, position, drop caps and rules intact.

Redaction that removes

Text under a redaction is stripped from the file and verified gone — not hidden behind a black box.

Edit, annotate & sign

Real editing, smart annotation and digital signatures with an intelligent snap engine that feels like a design tool.

OCR & smart forms

Make any scan searchable and fill forms with an engine that recognises fields for you. All processed locally.

Batch & submission

Process a whole folder in one pass, or fit an entire submission bundle under a target size. One corrupt file never stops the run.
