Frequently asked questions
How do I fill out a PDF form online?
Add the PDF, type into the fields shown next to it, then click Fill PDF form and download.
Why are no fields detected?
The PDF may be a scanned image or an XFA form. Only standard fillable (AcroForm) PDFs are supported.
What does flatten mean?
Flattening turns answers into regular page content so they cannot be changed in a PDF reader.
Can I add a signature to the form?
Fill the form first, then open the result in Sign PDF to add your signature.
Is this tool free?
Files under 200 KB are free. Larger batches have a one-time price based on total file size, shown before you process anything.
