Straight answers

Do my files get uploaded to your servers?

No, unless you explicitly pick the 48h cloud sharing option. Every tool runs in your browser through pdf-lib.js and PDF.js. The network monitor at the bottom left of each tool lists every request the page makes — you can check rather than trust us.

Do you track what I do or what files I process?

We count tool usage: which tool was opened, how long it was used, the browser language and the device type. No identifier, so two visits cannot be linked. No cookies, no advertising trackers, no third parties, no file content, no file names. The Maximum Privacy Mode switch on each tool turns even that off.

Can I use iWorkPDF without an account?

Yes, entirely. An account is only needed to save a file as a 48h cloud link. Every tool works without one.

What happens if I use the 48h cloud option?

The processed file is uploaded to Supabase storage (EU region), encrypted in transit. Access goes through a signed URL that expires after one hour, and the file itself is deleted after 48 hours.

Is it really free?

Yes. No premium tier, no paywall on a tool, no ads. The site is cheap to run precisely because your files are not processed on a server.

Was this site built with AI?

Yes — the interface and code were written with the help of generative AI tools, reviewed by a human. Your documents never go through an AI: the tools are deterministic libraries running in your browser. The one exception is the OCR tool, which uses a recognition engine (Tesseract) that also runs entirely in your browser. See the privacy policy.
