Private PDF tools for your browser and Android
PDF10x lets you merge, split, compress, convert, sign and protect PDFs free — in your browser or on Android — without uploading your files anywhere.
About PDF10x
PDF10x is the NowStacks PDF toolkit, built around one promise: your documents stay on your device. On the web, 21 tools run entirely in your browser using WebAssembly, so files are never uploaded to a server and there is no queue, sign-up, watermark or daily limit.
The web app covers the everyday jobs — merge, split, rotate and reorder pages, compress, convert between PDF and images — plus advanced tools that are usually paid elsewhere: OCR in 50+ languages, real text editing, e-signatures, watermark removal and AES-256 password protection.
The free PDF10x Android app brings 25 tools to your phone and works fully offline — it does not even request internet permission. Merge, split, compress, sign, watermark, number, crop, protect and unlock PDFs, convert images and text, and read documents in the built-in viewer, with no ads, accounts or watermarks. Need to digitise paper first? Scan it with ScanPro.
