Your file never leaves your device
Other PDF tools upload your file to their servers. PDF Lab doesn't. Everything runs in your browser — you can verify it by opening DevTools and watching the Network tab while you work.

Your file
Picked from your device. Stays where it is.
- 02🧠
Your browser
All processing happens locally using JavaScript libraries.

Download
The result is saved straight to your device. Nothing was uploaded.
* The page must be loaded once. After that, all PDF tools work without internet.

Frequently asked questions
- No. Every operation runs in your browser using JavaScript. Your file is loaded into your browser's memory, processed, and a result is saved to your device. Nothing is sent over the network.
- No. Because the processing happens in your browser, neither PDF Lab nor any third party has access to the file contents. You can verify this by opening your browser's network tab while using the tools — no file data is transmitted.
- Yes — once the page and required libraries are loaded in your browser, all PDF processing continues to work without an internet connection. PDF Lab is a web app, not a desktop installer, so the page itself must be loaded once before offline use is possible.
- Yes, the core tools are free with no signup, no watermark and no per-file limits beyond your device's memory. PDF Lab is built and maintained by Actwise as part of our public toolkit.
- There is no enforced limit, but performance depends on your device's memory. Most modern browsers comfortably handle PDFs up to about 100 MB. Very large files may slow down your browser tab.
- PDFs often contain contracts, IDs, medical records, financial statements and other sensitive information. Most online PDF tools upload your file to their servers — even when they promise to delete it later. PDF Lab eliminates that risk entirely by never uploading in the first place.
