Only for iPhone
Free · In‑App Purchases
iPhone
Vellumo turns your iPhone into a complete document workflow — scan, recognize text, edit, sign, watermark and share PDFs. Your documents never leave your device — scanning, OCR, and editing all happen locally.
SCAN ANYTHING
Capture single pages or multi-page documents with auto-edge detection and perspective correction. Import existing photos and PDFs from Files, Photos, or any app via the share sheet. Drag and drop files directly into your library.
OCR THAT WORKS IN YOUR LANGUAGE
Extract searchable, copyable text from your scans using Apple's on-device Vision OCR. Recognizes text in all languages supported by Apple Vision, including English, Czech, Slovak, German, Spanish, French, Italian, Polish, and Portuguese — with new languages added by Apple over time. Edit recognized text inline. Read OCR text aloud with synthesized speech.
EDIT PDFs LIKE A PRO
Reorder pages with drag and drop. Rotate, delete, split, or extract page ranges. Merge multiple documents into one. Highlight, underline, strike-through, and add free-text annotations in 6 colors. Redact sensitive areas with drag-to-select rectangles. Add bookmarks. Adjust scan brightness, contrast, and saturation.
SIGN AND SEND
Draw your signature with finger or Apple Pencil, save it, and place it anywhere on a PDF with custom size and position. Build a signature gallery for repeat use. Send signed documents via Mail, Messages, AirDrop, or Wi-Fi sharing — all without printing.
PROTECT YOUR EXPORTS
Add custom watermarks to exported PDFs — your text, your placement, your style. Perfect for "DRAFT", "CONFIDENTIAL", or branding without using a separate app.
ORGANIZE INTELLIGENTLY
Folders with unlimited nesting. Tags for cross-cutting organization. Custom folder colors and icons. Soft-delete trash with configurable retention. Bulk actions for selecting and managing multiple documents.
FIND ANYTHING INSTANTLY
Full-text search across all OCR'd documents with contextual snippets. Spotlight integration — find your scans directly from iOS search. Deep links to jump straight to a document.
PRIVACY YOU CAN VERIFY
Vellumo is built privacy-first:
- All scanning, OCR, and editing happens on-device — your documents never touch our servers, because we don't have any
- Anonymous, privacy-friendly usage analytics only (EU-hosted, no ad SDKs, no cross-app tracking)
- No account required — just download and start scanning
- Optional iCloud sync uses your private CloudKit (we never see your documents)
- Locked folders with biometric protection — independent of app lock
- Analytics data is never linked to your identity — see our Privacy Policy for details
WORKS WHERE YOU DO
Home screen widgets for quick scanning. Share Extension to import from any app. Wi-Fi sharing for fast local transfer between devices.
CUSTOMIZE EVERYTHING
App language in 7 locales. Light, dark, or system theme. Custom accent color. PDF quality presets. Document naming templates with date and counter tokens.
FREE FOREVER FOR LIGHT USERS

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Vellumo 1.2 — a calmer home screen and a signature flow that behaves.
• Signing no longer leaves the screen sideways. Save your signature and the document returns to portrait, with the placement view opening on the page you actually see.
• Trash has moved off the home screen. You'll find it under Settings › Library — nothing was deleted, and your retention setting is unchanged.
