Features

Everything you open a file to do.

PDFs, PNGs and JPGs open in the same window. Built on PDFium, the engine inside Chrome. Your edits save as standard PDF annotations, so Acrobat, Edge and Preview show them too.

Fast reading

Only the pages you see are drawn, so big files stay smooth. Zoom around the pointer, two-page view, outline, thumbnails and search.

Markup and signatures

Highlight, draw, add shapes, text boxes and sticky notes. Draw, type or photograph your signature and place it in one click.

Pictures and live text

Open PNG and JPG files like PDFs and save them as PDF. Text in scans and pictures is read with Windows OCR, so you can select, copy and search it.

Forms

Fill text fields, check boxes, radio buttons and drop-downs. Tab between fields. Form scripts never run.

Pages

Reorder, rotate, crop, delete and insert pages. Drag pages from one document into another, even across windows.

Safe by default

Undo for every edit. Saves write a temporary file first, so a failed save never damages the original.

Light or dark, it feels at home on Windows.

Portable
Monoview-0.1.1-win-x64.zip

Unzip it anywhere and run Monoview.exe. Nothing is installed, and .NET is included.

The builds are not code-signed yet, so Windows SmartScreen may show "Windows protected your PC" the first time. Click More info, then Run anyway. Needs Windows 10 version 1809 or later, or Windows 11, on x64.

Open a file and get on with your day.
