Privatool's PDF tools handle the most common document tasks without any software installation or file upload. Merge multiple PDFs into one, split a large PDF by page range, reduce file size before emailing, rotate pages, add a watermark, or password-protect sensitive documents. You can also convert a Word document (DOCX) to PDF directly in the browser. All tools use pdf-lib and PDF.js compiled to WebAssembly, so processing is fast and your documents are never sent to a remote server. This makes them suitable for handling confidential contracts, invoices, and personal documents.

Frequently Asked Questions

Are PDF files uploaded to a server?

No. All PDF operations run in your browser using PDF.js and pdf-lib compiled to WebAssembly. Your documents are processed locally and never transmitted to any server.

What is the maximum PDF file size?

There is no server-imposed size limit. Processing happens in your browser, so the practical limit depends on your device's available memory. PDFs up to 50 MB typically work without issues on modern devices.

Can I merge more than two PDFs at once?

Yes. The PDF merger lets you add as many files as needed, reorder them by dragging, and merge them all into a single PDF in one click.
