Frequently asked questions

The things people most ask us before getting started.

Is WHAT A PDF! really free?

Yes. All 37 tools are free for unlimited use, no watermarks, no required signup. We have an optional Premium plan (€7.99/mo) that unlocks larger file sizes and priority processing, but 95% of users never need it.

Are my PDFs uploaded to your servers?

For basic tools (merge, split, rotate, compress, extract pages) processing happens in your browser — the PDF never leaves your device. For tools that need heavy processing (OCR, AI, Word/Excel conversion) the file is uploaded to our European servers, processed, and auto-deleted within 1 hour. We never store or train AI on it.

Can I use WHAT A PDF! without an account?

Yes. All tools work without signup. An account is only required if you want to save signatures, see document history, or use collaboration features like form sharing.

Does it work on mobile and tablet?

Yes. The interface is responsive and works well on iOS, Android, and iPad. Some advanced tools (PDF editor, complex annotations) are optimized for larger screens but all are accessible.

What's the maximum PDF size I can upload?

On the free plan, up to 100 MB per file. The Premium plan raises the limit to 500 MB. This covers 99% of everyday documents (a 100-page PDF with images is typically 5–20 MB).

Can I edit scanned PDFs?

Yes. Use the OCR tool first to convert the scanned PDF to editable text, then pass it to the PDF Editor. OCR supports 100+ languages with high accuracy thanks to AI.

Is WHAT A PDF! GDPR compliant?

Yes. We operate from Spain (EU), our servers are in the EU, and our privacy model is "process-and-delete": no PDF is stored longer than 1 hour unless you choose to save it in your account. Our privacy policy details DPAs if your organization needs them.

How is your AI different from ChatGPT?

ChatGPT has a file-size limit when you upload PDFs (around 25 MB per upload). Our Chat with PDF handles documents up to 1,000 pages and indexes them to answer with exact page citations. Plus processing is per-document — your PDFs aren't mixed into training data.
