How it works — technically
Security is only real when it’s verifiable. Here’s exactly what happens when you use any tool on this site.
Runs in your browser
Every operation is executed by JavaScript running on your own device — using pdf-lib for PDF manipulation and PDF.js for rendering. No request is ever sent to our servers.
Zero upload, zero storage
Your file is loaded into browser memory and processed there. It is never transmitted over the internet. When you close the tab, browser memory is released — we have no copy, no access, nothing.
No account required
There is nothing to sign up for, no email to verify, no profile to build. An account you never created is an account that can never be breached. All 23 free tools work with no login, forever.
Our mission
PDF tools exist to process documents. And documents — the ones people actually need to edit — are rarely trivial. They’re tax returns, employment contracts, medical referrals, property deeds, and passport scans. The kind of files you’d never hand to a stranger on the street.
The dominant PDF tools on the internet treat your file as something to be uploaded, queued, processed on a remote server, then eventually deleted. You’re asked to trust their deletion policy, their security posture, and every vendor in their cloud stack. For the vast majority of people, that trust is extended without a second thought — because there was no alternative.
FixMyPDF is that alternative. We use the same open-source libraries (pdf-lib, PDF.js, Tesseract.js) that power serious applications — they just run on your machine instead of ours. Client-side processing is not a workaround or a compromise. It is the more secure architecture. We are making it the default.
Our goal is to build a complete PDF toolkit — 100+ tools — where every operation that can be done locally is done locally. Where the tools that genuinely require server-side processing (OCR at scale, Word conversion, Ghostscript compression) are clearly labelled as such, so you always know exactly where your file goes. No hidden uploads. No ambiguous data policies.
These are the documents FixMyPDF is built for. The ones where “we delete files after 2 hours” is simply not good enough.
What we don’t do
These are not aspirations or policies we intend to follow. They are architectural facts.
We never see your files
All processing happens in your browser. Our servers serve HTML, CSS, and JavaScript — nothing else.
We never store your files
There is no database of your PDFs. There is no temporary storage bucket. There is no 2-hour deletion timer, because there was never a copy to delete.
We have no server that receives your data
Our VPS serves static files. There is no upload endpoint. No API route that accepts file data. You can inspect the network tab in your browser DevTools on any tool page and verify this yourself.
We don’t require an account for any free tool
No sign-up wall, no email gate, no “3 free uses then register.” All 23 free tools are fully accessible without any account, indefinitely.
We don’t sell your data
We collect anonymised analytics through Google Analytics (page views, browser type, country). That’s it. We have no personal data to sell, and we don’t.
Verify it yourself
Open any tool, load a PDF, then open your browser’s Network tab (F12 → Network). Filter for “Fetch/XHR”. You will see zero requests carrying your file data. The source code is on GitHub — open to inspection.
