How to Fix Cannot Type into a PDF and Add Fillable Fields
Question details
The user is unable to type text into a PDF document and needs a way to add fillable fields or directly input text.

- Product
- Adobe Acrobat / PDF
- Device & OS
- not provided
- Scenario
- Attempting to fill out or edit a PDF document that lacks interactive form fields or has been flattened into a static image.
- Observed behavior
- Typing on the keyboard has no effect because the PDF behaves like a static document without designated, interactive text fields.
Check if the PDF document requires a password or has editing restrictions enabled, as security settings will prevent you from typing or adding form fields regardless of the tool you use.
Use the Fill & Sign Tool for Manual Text Entry
If the form is not interactive and you only need to complete it yourself, use the Fill & Sign feature to manually overlay text onto the document without creating complex form fields.
This is the fastest method for documents that have been flattened or converted to images, as it bypasses the need to author interactive form fields.
Open your document in Adobe Acrobat or Acrobat Reader. Navigate to the right-hand pane and select the 'Fill & Sign' tool.
Click anywhere on the document where you need to input information. A floating text box will appear on the page.
Type your text into the box. You can adjust the font size by clicking the small or large 'A' icons above the text field, then save the document.

Add Interactive Fields with Acrobat Pro Prepare Form Tool
Best used if you need to create a reusable fillable form for other people to type into easily.
Obtain the Original Interactive PDF
If the file was exported improperly from design software like InDesign or flattened during a print process, the easiest fix is to request the correct version.

Frequently Asked Questions
Why did my fillable PDF suddenly turn into a flat image?
This usually happens when the PDF is processed through a 'Print to PDF' virtual printer instead of being saved directly, or if the document creator deliberately flattened the file to lock the content and prevent further editing.
Can I unlock a secured PDF to type in it?
If the document is restricted by the author with a permissions password, you will not be able to type or add form fields until you enter the password under the document's security properties to unlock it.
How do I type on a scanned PDF document?
If the PDF is a scanned image, it contains no actual text data. You can either use an OCR (Optical Character Recognition) tool to convert the image into an editable document, or simply overlay text boxes using a Fill & Sign or Add Text tool.
Is there a way to make an InDesign PDF interactive?
Yes. When exporting your layout from Adobe InDesign, you must select 'Adobe PDF (Interactive)' from the format dropdown rather than 'Adobe PDF (Print)'. This ensures your buttons and form fields remain functional.
