A real document, broken to its pixels and rebuilt in front of you — compressed, converted, edited. Every atom stays on your machine.
Most document tools quietly send your files somewhere else to work on them.
VellumDoc doesn't. Everything you're about to watch happens on your own Mac.
A scanned contract, a photo-laden report, a deck full of renders. Too big to email, too big to file, too big to move.
VellumDoc finds each embedded image and recompresses it to its displayed size — discarding invisible resolution while the page looks identical.
Every formula, chart, signature and layout survives exactly. It isn't compression that degrades — it's optimisation that keeps.
A PDF you need to edit in Word. A deck locked in PDF. Converters online mangle the layout — and see your file.
PDF to Word, PowerPoint or Excel — every glyph, colour, column and drop-cap carried to its new place. Even a 60-point capital keeps its size.
99.4% of the text retained, position drift under measurement — the most faithful offline conversion we could build.
Fill a form, fix a typo, add a signature — and suddenly you need three apps and a print-scan cycle.
A snap engine recognises fields, checkboxes and signature lines — so filling, ticking and signing feels like a design tool, not a fight.
Real edits to the real file, saved right where it lives. No flattening, no re-export, no third app.
Not a byte uploaded. Not a document logged. The engines run where your files already are.
Beyond the three flagships, VellumDoc carries a full document toolkit — every one running on-device.
Text under a redaction is stripped from the file and checked gone — not hidden behind a black box.
Turn any scan into searchable, selectable text — recognised entirely on your device.
Run any operation across a whole folder in one pass. One corrupt file never stops the run.
Fit a whole bundle of files under a single upload limit — automatically.
Combine, reorder or pull apart PDF pages with a clean, direct interface.
Highlight, comment and place digital signatures with a smart snap engine.
Fill PDF forms with an engine that recognises the fields for you.
Stamp, watermark and lock PDFs before they leave your hands.
Combine a stack of images into a single clean PDF in one step.
Thirty days, every engine, no card and no account. Point it at your heaviest PDF and watch it stay on your machine.
