## FAQ

### How do I make a PDF fillable?

To make a PDF fillable, upload your form to pdf.net and drag the fields it needs onto the page: text boxes, clickable checkboxes, dates, and a signature field. Then download the fillable PDF, or share it with whoever has to complete it.

### Why can't I check the boxes in my PDF?

Because those boxes are printed on the page rather than being interactive fields, so there is nothing to click. Place real checkboxes over them with pdf.net and you can tick them instead of typing an X.

### Can I make a scanned form fillable?

Yes, you can make a scanned form fillable. Upload the scan or a photo of the printed form and place text fields, checkboxes, and signature boxes over the layout. The scan stays underneath as the background.

### What if my form already has some fields?

The Make it fillable toggle appears when a form has no interactive fields at all. If yours already has a few, you can still add the missing ones yourself: place the extra text boxes, checkboxes, or signature fields wherever the form needs them.

### What's the difference between an editable PDF and a fillable PDF?

An editable PDF lets you change the existing text and images. A fillable PDF keeps the layout fixed and adds interactive fields that someone else completes.

### Is there a limit on how large a form can be?

Automatic field detection currently works on forms of up to 200 interactive fields and up to 100 pages. Above that you can still place the fields yourself, and we are raising both limits.

### How secure is the pdf.net fillable PDF tool?

The pdf.net fillable PDF tool is secure: your files are encrypted with AES-256 at rest and TLS in transit. Forms you upload are saved to your account, and you can delete any of them whenever you want.

### How can I make a PDF fillable offline?

To make a PDF fillable offline, you would need to download a third-party tool that works without an internet connection. Doing it online with pdf.net is much more convenient, as there is nothing to install: upload your form, drop in the fields, and download it.

### Can I use pdf.net on a Mac, Linux, or smartphone?

Yes, you can use pdf.net on a Mac, Linux, and smartphones. Essentially, you can use our online PDF editor on any device with a browser and an internet connection.

### What file formats are supported?

pdf.net accepts PDF, Word documents (DOC, DOCX), and JPG, PNG, and HEIC images. Anything that is not a PDF is converted first, and then you add the fields.

### Can I fill in the form myself after I make it?

Yes, you can complete it in the same editor. You can also upload a document with your details and let our AI form filler do it for you, in any format we support.
