Privacy
Short version
Your PDF never leaves your browser. We do not see it. We cannot see it. There is no upload step, no server-side processing, no "anonymous telemetry," and no third-party script that calls home. The site's Content-Security-Policy header blocks every cross-origin network request at the browser level, regardless of what the code attempts.
You can verify this yourself in 30 seconds — see how to verify this tool.
What is processed
When you drop a PDF into the page, your browser reads it into memory using the standard FileReader API and hands it to pdf-lib, a JavaScript library that runs locally inside this page. pdf-lib rewrites the PDF — re-encoding embedded images, stripping metadata, dropping unused objects — and the result is offered to you as a download. The original and the result both live in your device's memory and are released when you close the tab.
What is collected
- By the operator of this site: nothing. There is no analytics provider, no tracking pixel, no error-reporting service, no "session replay," no cookies set by us, no fingerprinting.
- By the hosting provider (Cloudflare): standard server access logs (your IP address, user-agent, the URL you requested) for the purpose of serving the page and protecting it from abuse. We do not query, export, or analyze these logs. See Cloudflare's privacy notice for details.
What is stored on your device
Nothing. This site sets no cookies, writes no localStorage, writes no sessionStorage, opens no IndexedDB, and registers no service worker. You can verify this in your browser's DevTools → Application tab.
Third-party scripts
None are loaded. All JavaScript and WebAssembly is served from this same domain. We deliberately do not use a CDN for libraries — that would let a third party see every visitor's IP, and we won't trade your privacy for a few kilobytes of cache.
Children
The site is not directed at children and does not knowingly collect any data about anyone, including children. There is no account system to age-gate.
Changes
If this policy ever changes, the "Last updated" date above will change. The substantive promise — that your PDF never leaves your browser — will not change without the product itself fundamentally changing.

If something on this page is wrong, unclear, or you've found evidence that contradicts it, the best place to start is the verification guide — it lists every claim with the means to check it. If the discrepancy is real, that's the page that needs updating.
