Private by design

Most online PDF services upload your document to their servers. ZIYNU's PDF tools work differently: the PDF engine runs inside your browser, so the file is opened, changed and saved on your own device. That matters for CNIC copies, bank statements, degrees, contracts and anything else you'd rather not hand to a stranger.

The trade-off is honesty about limits. Tasks that genuinely need a server — accurate PDF to Word conversion, OCR and AI document questions — are marked Coming soon rather than pretending to work. Need the full picture on data? Read our Privacy Policy.

Frequently asked questions

Are my PDFs uploaded to ZIYNU?

No. Every PDF tool on this page runs in your web browser. Files are opened and processed on your device, and results are created there too. Nothing is sent to our servers.

Are the PDF tools free?

Yes. All tools are free and don't need an account.

What is PDF Doctor?

A checker that looks for common problems — blank pages, mixed page sizes, low-resolution images, unembedded fonts, hidden metadata and scripts — explains them and offers safe fixes.

Can ZIYNU convert PDF to Word or Excel?

Not yet. Accurate Word and Excel conversion needs server processing, which we're planning carefully so it stays private. Those tools are marked “Coming soon”.

Is there a file size limit?

PDFs up to 150MB can be opened. Very large or image-heavy files depend on your device's memory; a desktop browser handles them best.
