About PDFtools
We believe working with PDFs should be simple, fast, and private. Every tool runs entirely in your browser — your files never touch a server.
Privacy by Design
Every file you process stays on your device. We use client-side JavaScript and WebAssembly to handle all PDF operations directly in your browser. Nothing is ever uploaded to a server.
Instant Processing
No server queues, no waiting. Your files are processed instantly using your device's computing power. The result is available in seconds, not minutes.
Open Source
Our code is open for inspection. You can verify exactly how your files are processed. Transparency builds trust.
Works Offline
Once loaded, many of our tools work without an internet connection. Perfect for handling sensitive documents anywhere.
No Account Required
No sign-ups, no email collection, no user tracking. Just open the tool and use it. Simple as that.
Free Forever
Every tool is completely free with no usage limits. No freemium tricks, no premium tiers, no ads.
How it works
When you select a file, it's read directly into your browser's memory using the File API. We then use libraries like pdf-lib and PDF.js to process the file entirely in JavaScript. The result is generated as a Blob and downloaded directly to your device. At no point does any data leave your browser.
