Frequently Asked Questions
- What is the difference between this tool and Fill in PDF?
- Fill in PDF writes your answers permanently into the document, so the result is flat. This tool makes the document itself fillable: the fields become real form fields the recipient can type into.
- How do I make a PDF fillable for free?
- Upload your PDF, let us detect the fields or place them yourself with a click, name them and download. No signup, no cost.
- Which field types can I create?
- Text fields, date fields, checkboxes, multi-line text areas and comb fields with a fixed number of characters, for example for ID or account numbers.
- Does the form work in Adobe Acrobat?
- Yes. The fields are genuine AcroForm fields following the PDF standard, so they work in Acrobat, Chrome, Edge, Firefox and Apple Preview.
- Can the recipient save what they filled in?
- Yes. Modern PDF readers and browsers save filled form fields, and the document can be forwarded with the content intact.
- Does the tool change how my document looks?
- No. The fields are placed on top of the existing content with a thin border. Text and graphics are untouched.
- What happens to my file?
- It is processed on servers in the Nordics and deleted automatically, typically within an hour. You can download a deletion certificate afterwards as documentation.
