Filling out a PDF form used to mean printing, writing by hand, scanning and emailing back. That four-step process is now a single step: open the form in an online tool, fill it in, and download the completed document. No printer, no scanner, no physical paper.
MakeitPDF's Fill & Sign PDF tool handles both interactive forms (with clickable fields) and flat forms (scanned or non-interactive) — letting you type anywhere on the page, tick boxes, add a signature, and download a finished PDF.
Key takeaways
- Fills both interactive PDF forms and flat (non-interactive or scanned) forms.
- Type text, check boxes, add dates and apply your signature in one workflow.
- The filled form is downloaded as a standard PDF — no special viewer needed to open it.
- Works on desktop and mobile — fill forms on your phone as easily as on a computer.

Interactive forms vs flat forms
PDF forms come in two types, and knowing the difference helps you choose the right approach:
- Interactive forms — also called AcroForms — have proper clickable fields. When you click on a field, a cursor appears and you can type. Checkboxes click on and off. The tool detects these fields and lets you fill them natively.
- Flat forms — scanned or printed forms saved as PDF images — have no interactive fields. They look like forms but there's nothing to click. For these, the tool lets you place text boxes, checkmark symbols and signatures anywhere on the page.
You can tell the difference by trying to click on a field in your PDF viewer. If a text cursor appears, the form is interactive. If nothing happens, it's flat.

Adding a signature to a filled form
Most forms that need to be filled out also need a signature. The Fill & Sign PDF tool includes a full signature creation workflow alongside the form-filling tools — so you can fill and sign in a single session without switching tools.
If you need to sign a document that doesn't need any form filling, the dedicated Sign PDF tool is a quicker experience for signature-only use cases.
After filling and signing, the completed form is a standard, flat PDF. The form fields (if interactive) are locked in their filled state. Recipients can view the completed document in any PDF viewer — no special software required.
Frequently asked questions
Can the recipient edit my answers after I submit the form?
After clicking Apply Changes, the form content is flattened into the PDF. Interactive fields are converted to static content — the answers appear as text but are no longer editable by the recipient.
What if I made a mistake in the form?
While you're working in the tool, you can edit or delete any field you've filled. Once you've downloaded the completed PDF, upload it again and use the Edit PDF tool to cover the error with a white rectangle and add the correct text on top.
Can I fill forms that are password-protected?
Protected forms may restrict filling. If the form is locked, remove the password first (you'll need the original password to do this), then fill and sign the unlocked copy.
Is my form data stored on your servers?
No. Your file is processed and immediately made available for download, then deleted from our servers after your session. We do not store, read or access the content of your documents.
