Is PDFNina really free?+

Yes. Every tool is free, with no watermarks and no account needed. Tools that run in your browser are unlimited. With a free account, Office conversions and signature requests are unlimited too; AI tools have a small daily limit for everyone.

Where are my files processed?+

Most tools, including merge, split, compress, edit, sign, OCR and conversions from PDF, run entirely on your device. Word, PowerPoint, Excel and web page conversions and the AI tools need our servers. Files sent there are processed and deleted immediately.

Do I need to install anything?+

No. PDFNina works in any modern browser on Windows, Mac, Linux, iOS and Android.

Can I use the result in another tool?+

Yes. When a tool finishes, pick “Continue with” to send the result straight into the next tool. No downloading and re-uploading.

Is there a file size limit?+

On-device tools are limited only by your device’s memory, so files of several hundred megabytes are fine on most computers. Server conversions accept files up to 50 MB.

Your next PDF is three clicks away.
