ENTERPRISE-READY

Governed By Design

Real text reflow

Edit multi-line paragraphs with automatic word wrap and line height — text pushes and pulls across pages, powered by PDFium and HarfBuzz.

Fonts preserved

Embedded fonts are reconstructed for editing, with graceful fallback that keeps the original look.

Annotations & markups

Highlights, underlines, strikeouts, shapes, sticky notes and freehand ink — written into the PDF.

Permanent redaction

Blackout that truly removes the underlying text and image objects, not just a box on top.

Signatures & stamps

Place a signature image or custom stamp anywhere, resizable to fit.

Page operations

Insert, delete, rotate and reorder pages, and replace images inside the document.
