What PDF tools are available?

We offer PDF merging, splitting, compression, text extraction, metadata viewing, password protection, page rotation, and format conversion.

Are my PDFs uploaded to a server?

No. All PDF processing happens client-side in your browser using JavaScript libraries. Your documents are never uploaded and never leave your device.

What is the maximum file size for PDFs?

Since all processing is done in your browser, the practical limit depends on your device's memory. Very large PDFs with many pages may require more memory.

Can I protect a PDF with a password?

Yes, our PDF protection tool lets you set owner and user passwords, and restrict printing, copying, and editing permissions.
