Our mission
Professional PDF tools shouldn't require a £180/year subscription. Adobe Acrobat and Nitro Pro are excellent products for power users who need them daily — but most people just need to merge two files or compress a scan before emailing it.
We built PDF Master to cover that gap: every tool is free, runs online, and works without an account. We'll never ask you for a credit card.
Six of our tools use AI (powered by Anthropic Claude) for tasks that genuinely benefit from it — summarising long research papers, translating contracts, extracting structured data from forms. Everything else stays on your device.
What we stand for
Privacy by default
Most tools process your files privately, so your documents never touch our servers — there is nothing to intercept, log, or leak.
Genuinely free — forever
No freemium tricks, no expiring trials, no watermarks. PDF Master is funded by non-intrusive contextual ads, not paywalled features.
Fast by design
We skip slow uploads wherever possible, so merging, splitting, rotating, and watermarking PDFs happens almost instantly.
AI when it counts
Six AI-powered tools for summarising, translating, extracting data, and chatting with documents — powered by Claude and only sent to our servers when necessary.
