What we collect (almost nothing)

This page is short on purpose. Most privacy policies hide their answers inside legal boilerplate. We'd rather you understand ours in two minutes.

Your files

Tools tagged "In-browser" don't see your files at all. When you drag a PDF onto a browser-based tool, the bytes go from the file picker straight into a WebAssembly module running in your browser tab. Nothing in that path makes a network call with your file's contents. You can verify this in DevTools → Network.

Tools tagged "Server" (currently none in v1, planned for OCR later) will process files on a server and delete them immediately after the response. We'll never have a server tool without saying so clearly on the tool page, and we'll never quietly switch an in-browser tool to server-side processing.

Analytics we use

We use a privacy-friendly analytics service (Plausible or Cloudflare Web Analytics, depending on the host). It logs page views without cookies, doesn't share data with advertisers, and doesn't fingerprint you. From it we learn things like "which tools are getting used" and "which page is broken in Firefox"; we don't learn who you are.

The specific events we record about tool usage:

• Tool viewed (just the tool slug, e.g. /fill-pdf).
• File added (your file's MIME type + a size bucket like "5–25MB" — never the file name or contents).
• Tool started / succeeded / failed (with a duration and, if failed, the error reason).
• Download clicked.

None of these include your filename, your file's contents, or any personal identifier.

Errors we track

If a tool crashes, the JavaScript error message is sent to Sentry so we can fix it. The error includes the stack trace, the browser version, and the tool slug. It does not include your file or its contents.

Cookies

We don't set tracking cookies. Your browser may store a few small preferences locally (last-used filename, saved signature shape) — these stay on your device and aren't sent anywhere.

If you contact us

Emails to hello@pdfwox.com land in a regular inbox we read. We keep them for as long as it's useful to keep them and don't share them with anyone.

Changes

If we change this policy in a way that affects users, we'll update the "last updated" date at the top and (for material changes) post a note on the homepage for at least a month.

Questions
