About DocuMaster PDF Studio
DocuMaster PDF Studio is a free set of 24 PDF tools – reader, read aloud, scanner, OCR, merge, split, compress, sign, fill forms, convert and protect – made by Ikonet Solutions, an independent software studio run by Inza Kone in Piacenza, Italy.
Most online PDF services upload your documents to their servers. We chose the opposite approach: every tool runs inside your browser or inside the app, using open-source engines such as PDF.js, pdf-lib, QPDF and Tesseract. Your contracts, payslips and IDs never leave your device, and the tools keep working even offline.
The website is free and supported by advertising. The same tools are available as an app for iPhone, iPad and Android, with a camera scanner, the option to open PDFs directly from other apps and DocuMaster Pro, a single purchase that removes the ads.
We publish detailed guides, keep the tools up to date and answer every message personally. If something does not work as you expect, or you would like a new tool, write to us: many features exist because a user asked for them.
