Frequently asked questions

What does browser-local mean?
Browser-local means all processing happens on your device using JavaScript. Your files are never sent to a server, cloud, or any third party.
Are these PDF tools safe for sensitive documents?
Yes. Because nothing is uploaded, these tools are safe for tax returns, contracts, invoices, bank statements, legal documents, and any other sensitive content.
Do I need to install anything?
No. Everything runs in your web browser. No plugins, extensions, or desktop software required.
What technology powers these tools?
The tools use pdf-lib, an open-source JavaScript library that can create, modify, and read PDF documents entirely in the browser.
Is there a file size limit?
The only limit is your browser's memory. Most modern browsers handle files up to several hundred MB without issue.
