Folio. Work with documents. Not around them.

Read, edit, organise and sign your documents in one remarkably simple app. On Mac, iPad and iPhone.

Edit, sign and mark up.
Right on the page.

No converting, no retyping, no printing.

  1. Same font. Same line.
  2. Stop printing things to sign them.
  3. Point at the exact line.
  4. Wrong order? Drag it.

Automatic text recognition.

Scanned pages turn into real text the moment you open them. Search them, copy from them and edit them like any other document.

Edit text down to the last detail.

Choose the font, size and colour. Move, resize and rotate text boxes, and set precise indents. Arabic, Hebrew and Indic scripts are fully supported.

Rearrange anything.

Move, resize and replace images. Split a document, merge several into one, or drag pages into a new order.

Mark it up. Then change your mind.

Highlight, draw, and add notes, stamps and measurements, then edit any of them later. On iPad, Folio turns your handwriting into typed text.

Not hidden. Removed.

Folio’s redaction deletes sensitive content from the file itself, instead of covering it with a black box.

Fill in forms. Sign them securely.

Fill in any form, or create your own with interactive fields. Sign with a certificate-based digital signature that shows who signed, and whether anything changed afterwards.

Understand long documents faster.

Get a summary, ask questions, rewrite a paragraph, translate it or have it read aloud. Powered by Apple Intelligence or a model running on your own Mac.

Your documents stay yours.

No account, no servers, no analytics, no tracking. Folio never sends your documents to us.

Built on our own engine.

Folio runs on PDFCore, a document engine we wrote ourselves in Swift, with no third-party code. It gives us full control over every page, from how it’s drawn to how its text is set.

rudi. is a technology studio.

Folio is what we make when nobody’s asking.
