How this site is different

Works in your browser

Drag a file, get a result. The page does the work — no server round-trip.

No signup, ever

Every tool is free and accountless. No email, no paywall, no watermark.

Files stay private

Client-side tools never upload your file. Server tools delete it immediately.

Free PDF tools that work in your browser

PDFWox is a collection of free PDF utilities that run entirely inside your browser tab. Fill out forms, convert images, sign documents, redact sensitive content, add or remove watermarks, protect files with a password, and run OCR on scanned pages — all without uploading anything to a server.

Every tool on this site is free, requires no account, and leaves no watermark on your output. Because the work happens locally using WebAssembly and modern browser APIs, your files stay on your device from start to finish. The privacy guarantee is structural, not a policy promise: there is no upload step, so there is nothing to leak.

The tools cover the most common everyday PDF tasks: converting iPhone HEIC photos or PNG and JPG images into a PDF, filling in form fields, making a static PDF fillable, signing, annotating, redacting, protecting with AES-256 encryption, unlocking a password you already know, adding or removing watermarks, and extracting text with in-browser OCR. New tools are added regularly — see the changelog for what is live.

The differentiator

Why a browser-based PDF tool is safer than an upload site.

When the page does the work, your file never leaves your machine. Nothing to leak, nothing to retain, nothing to subpoena. We explain how it works — and where the limits are — in one read.
