PDFShore is an independent project building privacy-first PDF tools that run entirely in your browser. Sixteen tools, including AI workflow helpers like a PDF token counter, Markdown converter, and redactor, all processed on your device with no server uploads.
Most online PDF tools upload your file to their servers. Sometimes that's fine. Often it's not, especially for contracts, IDs, medical records, or anything you'd rather keep private. We thought there should be a free option that simply doesn't see the file.
Modern browsers can do real PDF work without a server. We use pdf-lib and PDF.js compiled to WebAssembly, running in Web Workers so the page stays responsive. The same architecture powers the AI tools: the token counter runs gpt-tokenizer locally, and the Markdown converter uses Tesseract OCR on-device.
Built by Max Shore, one developer working on this in the open. No VC money, no growth team, no dark patterns. Ads pay the hosting bill.
