Frequently Asked Questions
Is this service really free?
Yes, fillonlinepdf.com is 100% free to use. There are no hidden fees, no credit cards required, and no limits on how many forms you can fill.
Is my data secure?
Absolutely. Unlike other PDF editors, we do not upload your files to our servers. All processing happens locally in your browser using secure WebAssembly technology. Your data never leaves your computer.
Do I need to sign up?
No. We believe in speed and simplicity. You don't need to create an account or provide your email address to use our tool.
Can I save my filled PDF to finish later?
Currently, we allow you to download the finished, filled PDF. We do not store your incomplete forms on our servers (because we don't have servers!). We recommend filling the form in one go.
What happens to my file after I close the tab?
Since files are processed in your browser's temporary memory, as soon as you close the tab or refresh the page, your file is wiped from memory. We cannot recover it because we never saved it.
