Organize and assemble

Pages you can move

Reorder, rotate, duplicate or delete pages. Insert a document between two existing pages.

From several files to one

Assemble PDFs on the merge board. To extract pages, drag the selection into a Windows folder.

The finishing touches

Crop pages, add numbers or watermarks, then export or print.

Before you begin

Scripts, digital signatures and proprietary structures in complex PDFs may not survive a page copy.

Search and annotate

From scan to text

OCR adds a searchable text layer you can select and copy. English, French, German, Spanish and Dutch are available locally.

Your comments, on the page

Highlight, underline, draw or add notes, shapes and arrows. Annotations can include an author and replies.

Before you begin

OCR results depend on the document. No accuracy rate or recognition of all handwriting is guaranteed.

Visual signatures

Import a handwritten signature to place it on a document. This image is not a digital certificate.

Plan measurements
