Frequently Asked Questions
Common questions about ExactPDF's security, privacy, and features.
Is ExactPDF really free?
Yes! ExactPDF is completely free to use. There are no hidden fees, paywalls, or credit systems. We operate on a voluntary contribution model, meaning you can support us if you want, but it's not required.
Is it safe to process my private documents?
Absolutely. ExactPDF uses a 'Privacy-First' architecture. All processing happens locally in your browser using WebAssembly. Your files are never uploaded to our servers, so we literally cannot see them.
What security measures does ExactPDF implement?
We implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, X-XSS-Protection, and Referrer-Policy. All APIs have rate limiting, file type validation, and filename sanitization. Read our security blog for full details.
What new tools are available?
We recently added PDF Reader (view PDFs in-browser with zoom and navigation), PDF Annotation (highlight and underline text), Batch QR to PDF (generate multiple QR codes), Add Page Numbers, Unlock PDF, Extract Pages, and PDF to Text.
Why does it say 'Client-side processing'?
Client-side processing means the heavy lifting is done by your own computer's processor (CPU) rather than a remote cloud server. This ensures your data stays on your machine and often results in faster processing for small to medium-sized files.
Can I use ExactPDF offline?
Yes, once the page and necessary resources are loaded, many tools can function without an active internet connection because the code runs in your browser.
What happens to my uploaded files?
Nothing happens to them outside of your device. They are loaded into your browser's memory, processed, and then the result is offered as a download. After you close the tab, the data is wiped from memory.
Do you use cookies or tracking?
We only use essential cookies for language preferences. There's no Google Analytics, no Facebook Pixel, and no third-party tracking scripts. You can verify this yourself in your browser's Developer Tools.
How can I verify your privacy claims?
Open Developer Tools (F12), go to the Network tab, and process any PDF. You'll see zero file uploads. You can also disconnect from the internet and test - most tools work offline.
How can I support ExactPDF?
If you find our tools useful, you can make a voluntary contribution via 'Buy me a coffee' or simply share the tool with your friends and colleagues!
