Vellum - HTML viewer

Some HTML documents and statements just won't open in Mail or Safari on your iPhone—leaving you stuck, or reaching for a Windows PC. Vellum is the simple, fast viewer that opens them right where you are.

Wherever the file arrived—Mail, a messenger, Files, or a browser—just tap "Open in Vellum" and it opens instantly, rendered cleanly and completely.

Opens right from any app
See a document in Mail or Files? Tap "Open in Vellum" and it's there at once. No setup, no sign-up. A built-in guide walks you through it the first time.

Opens what others can't
HTML files and statements that won't display elsewhere open perfectly here—nothing broken, nothing missing.

Read it your way
Search for any word inside a document, pinch to zoom in as close as you like, and export an HTML statement as a clean PDF to keep or share.

Auto-saved and organized
Files you open are saved automatically and grouped by month. Pin the ones you reach for, sort by date or name, and find anything again in seconds.

Yours alone
No account, no servers, no ads. Lock the app with Face ID, hide its contents when you switch apps, and let old files clean themselves up. Everything stays on your device.

Open any document, right from your hand.
