Viper PDF

Merge, split, compress and edit PDFs locally — your files never leave your computer.

Viper PDF is a free toolbox for working with PDFs that runs entirely in your browser. Your files are never uploaded to any server. WHAT YOU CAN DO • Merge: combine several PDFs and images (JPG/PNG) into a single PDF. • Split: select pages and save them as a new PDF. • Reorder: drag page thumbnails to change the order. • Compress: choose to keep quality or apply low, medium or high compression. • Export pages as JPG images. • Edit: open the built-in PDF editor to change text and make quick adjustments. • Compare: select two versions of a PDF and see exactly what was inserted, deleted, replaced or moved. The whole document is compared as one flow of text, so content that shifts to another page is not reported as a change. Export a report. • PDF to DXF (beta): convert vector PDF drawings into DXF files for CAD, keeping layers where possible. This feature is still being validated. PRIVATE BY DESIGN Files are processed locally on your computer. No account, no analytics, no tracking. The only network request is a small text file used for the banner at the top of the tool; it never contains your documents or any identifier. LANGUAGES English and Portuguese (Brazil), selectable inside the tool. Very large sets of files can exceed your browser's memory. Viper PDF tells you when that happens, so you can export what you have organized and add the rest in a second round.
