Built for people who work with PDFs every day.
Why PDFsuite exists
Most PDF tools make you upload your files to a stranger's server. Contracts, invoices, medical records, signed agreements - all sent over the wire to be processed, stored, and potentially breached. The "free" tools are especially troubling: if you're not paying, your data is the product.
PDFsuite started from a simple question: what if every PDF operation ran entirely on your own device? No upload step. No server waiting on the other end. Just WebAssembly doing the work on your machine, the same way native desktop software does - in your browser or in the Mac app, with nothing uploaded.
How it works
Every tool in PDFsuite runs on open-source libraries compiled to run on your device: pdf-lib for PDF manipulation, PDF.js for rendering, PDFium for redaction, and Tesseract for OCR in 11 languages. Your files are loaded into memory, processed, and the result is saved straight back to your device. The network tab in DevTools shows no upload during any operation - because there is no server to send your file to.
This isn't just a privacy promise. It's an architectural fact you can verify yourself. Open DevTools, go to the Network tab, filter for XHR requests, then run any tool. You'll see no file transfer and no upload of your document. The only requests are code or OCR language data being downloaded, never sent.
The product
PDFsuite ships a PDF editor plus 28 tools covering the full range of PDF work: merge, split, compress, rotate, reorder, crop, extract pages, delete pages, convert to and from Word and images, add watermarks and page numbers, protect with passwords, redact sensitive content, run OCR on scanned documents, and more.
It runs in your browser and as a Mac app for macOS 13 or later, and it works offline. You can try every tool free before you buy.
