Questions about Fill PDF Form

Is Fill PDF Form free to use?

Yes. Fill PDF Form is free and unlimited on Wispdf, with no account needed. You can fill as many forms as you like, as often as you like, because the work happens on your device. The only practical limit is your device's memory, comfortably around 1 GB of PDFs on a computer and less on a phone.

Are my answers sent to your servers?

No. Fill PDF Form runs in your browser, on your device. The form and everything you type into it, such as your name, address or passport number, stay with you. Nothing is uploaded, so there is nothing for us to store or delete. That matters most for visa, medical and employment forms full of personal details.

Why does Wispdf say my form is not supported?

Your file is most likely an older XFA form. XFA is an Adobe form format that some agencies and companies still use, and Fill PDF Form does not support it. Wispdf tells you clearly when it finds one. Ask the sender for a standard fillable PDF, or open the file in Adobe Acrobat Reader.

My PDF has no fields to click. Can I still fill it?

Fill PDF Form fills the fields that are built into a form. If your PDF is a flat page with blank lines and no fields, use Edit PDF to place text where the answers go, which is free. If you send the same form out often, Create PDF Form, part of Pro, makes it properly fillable.

Can I fill a PDF form on my iPhone or Android?

Yes. Fill PDF Form works in any modern browser on iPhone, iPad, Android, Chromebook, Windows, Mac and Linux. There is no app to download. Open the tool, choose the form from your files, tap into each field to type, and save the completed PDF to your phone, ready to email or upload where it needs to go.

Can I sign the form or stop my answers being changed?

Yes, with 2 more free tools. After you save the filled form, use Sign PDF to draw, type or upload your signature and add the date. To lock your answers so nobody can change them and they print the same everywhere, run the file through Flatten PDF. Both run on your device, just like Fill PDF Form.
