A small set of PDF tools that respect you

PdfWox is a focused toolkit for working with PDFs. Every tool runs inside your browser tab — your files never leave your device, and we don't ask you to sign up, pay for a subscription, or wait for a server queue to clear.

What this is

Currently 17 working tools, plus more on the way. The toolkit covers the everyday: filling and making PDF forms, turning iPhone HEIC photos into a shareable PDF, unlocking a PDF you have the password for, protecting one with AES-256, and the wave 2 and 3 tools — redaction, annotation, watermarking, signatures — ship over the coming weeks.

None of these are revolutionary on their own. What's different is that they all run on your device. There is no upload step, no "we delete after 1 hour" promise to take on faith, no account to remember the password to.

Why it's built this way

Most online PDF tools work by uploading your file to a server, doing the work there, and sending the result back. That model works fine for most PDFs. But the PDFs people care about most — tax returns, contracts, medical records — are the ones they're least comfortable sending to a server they don't control.

Browser-based PDF tooling didn't really work until recently. Modern WebAssembly lets us run the same C++ libraries (qpdf, libheif, pdf-lib's underlying primitives) inside the browser at near-native speed. We get to be a real PDF tool without ever touching your file. Why a browser-based PDF tool is safer than an upload site covers the architecture in more depth.

What it isn't

We're not trying to replace Adobe Acrobat. If you do high-volume document processing all day, a desktop tool will serve you better. If your workflow needs cryptographic signatures with a certificate authority, that's outside what a browser tab can do well.

What we are: the place you go when you need to do one thing to a PDF, quickly, without uploading it or paying for it.

How we'll stay free

For the in-browser tools, "free" is sustainable — we don't pay for a server to process your files. If we eventually offer server-side OCR or batch processing, those will likely have a paid tier, but the existing free tools stay free.
