How do I fill in a PDF form?
The document's fields are detected and listed in order. Fill them in, then save — either keeping the fields editable, or flattening them for good.
Fill PDF form
Complete a PDF form and lock your answers in.
The document's fields are detected and shown as a plain form. Once filled in, you can flatten the file: the answers become part of the page itself and nobody can change them afterwards.

Common questions
Should I flatten the fields before sending?
It depends who receives it. Flattening guarantees nobody changes your answers; leaving them editable lets the recipient complete their part.
Are my files uploaded to the internet?
No. This tool runs entirely in your browser: the document is opened on your device, processed there, and never sent anywhere. You can even go offline once the page has loaded.
Is it free, and do I need an account?
Free and unlimited, with no account and no sign-up. This tool costs us nothing because it runs on your machine, so we have no reason to ration it.
