About PDF Tools

We use pdf-lib and PDF.js to manipulate PDF files entirely client-side. No upload means faster processing and stronger privacy: your documents stay on your device.

Frequently asked questions

Do my PDFs get uploaded?

No. Every PDF tool here runs in your browser. The file is loaded into memory by JavaScript and is never sent to a server.

What PDF features are supported?

We support merging, splitting (single-page extraction), reordering, rotating, adding text, password protection, and image-to-PDF conversion.

Is there a file size limit?

There is no hard limit imposed by the tool, but browser memory is the practical ceiling. Files under 100MB generally work well on modern devices.
