What you need to create a fillable PDF form
To create a fillable PDF form in Adobe, you need Adobe Acrobat Pro (the paid desktop version), not the free Adobe Reader or the web-based Acrobat. Acrobat Pro gives you the form-building tools; the free versions do not. You start with either a blank PDF or a scanned document, then add text fields, checkboxes, dropdown menus, and buttons where people will enter information.
The process takes 15 minutes to an hour depending on how many fields you need and whether you are starting from scratch or converting an existing document. Once you finish, anyone with Adobe Reader (free) or a web browser can open and fill out your form — they do not need Acrobat Pro to use it.
Key Takeaways
- Adobe Acrobat Pro is the only Adobe product that lets you create fillable forms; the free Reader and web version cannot do this.
- You can start with a blank PDF, a scanned paper form, or an existing document, then add fields using Acrobat Pro's form tools.
- After you create the form, people can fill it out in Adobe Reader or any web browser without needing Acrobat Pro themselves.
- You can set fields to require certain formats (like dates or phone numbers) and lock parts of the form so people cannot edit them.
Starting with a blank PDF or existing document
Open Acrobat Pro and go to File > Create > Blank Document if you want to build a form from nothing. Name your file and choose the page size (Letter is standard for most forms). You now have a blank PDF ready for content.
If you already have a document — a Word file, a scanned image, or a PDF you designed elsewhere — open it in Acrobat Pro. Acrobat can convert Word documents and images to PDF automatically. Go to File > Open and select your document. Acrobat will convert it if needed. Once it is open as a PDF, you can add form fields on top of it.
For scanned paper forms, the image quality matters. A clear scan with good contrast works best. If your scan is blurry or dark, Acrobat's form recognition may struggle. You can still add fields manually, but it takes longer.
Using Acrobat's automatic form detection
Acrobat Pro can recognize form fields automatically on some documents. Open your PDF, then go to Tools > Prepare Form. Acrobat scans the document and attempts to detect text boxes, checkboxes, and other fields based on layout and spacing.
This works well on professionally printed forms with clear structure — tax forms, process templates, and standard questionnaires often convert cleanly. Acrobat places fields where it thinks they belong, and you can then adjust, delete, or add more fields by hand. On poorly scanned or hand-drawn forms, automatic detection may miss fields or place them incorrectly, so you will need to add or fix them manually.
After automatic detection finishes, review every field. Click on each one to check its position, type, and settings. Misplaced fields confuse people filling out the form.
Adding and configuring form fields manually
To add fields by hand, open the Tools menu and select Prepare Form. You will see a toolbar with field options: Text Field, Checkbox, Radio Button, Dropdown List, Listbox, Button, and Signature. Click the field type you need, then click on the PDF where you want it to appear.
For a text field, click and drag to draw the box size. A properties panel opens on the right. Name the field (use something clear like "First Name" or "Email Address" — this name appears in exported data). Set the field type: Text, Number, Date, Phone Number, or Percentage. If you choose Number or Date, Acrobat enforces the format so people cannot enter text in a number field.
For checkboxes and radio buttons, click once to place them. Checkboxes let people select multiple options; radio buttons let them pick only one from a group. For dropdowns, draw the box, then type each option in the properties panel, one per line. People will click the dropdown to see and select from your list.
After you place a field, you can resize it by dragging the corners, move it by dragging the center, or delete it by selecting it and pressing Delete. Duplicate fields by selecting one and pressing Ctrl+D (Windows) or Cmd+D (Mac).
Formatting and protecting your form
Once all fields are in place, set their appearance. In the properties panel for each field, you can change the font, font size, and text color. Keep fonts readable — 11 or 12 point is standard. You can also set a background color for fields so they stand out from the form background.
To prevent people from editing parts of the form, lock the areas you do not want changed. Select the text or images you want to protect, then go to Tools > Protect > Encrypt with Password. Choose "Restrict Editing" and set a password. Anyone filling out the form can complete the fields, but they cannot edit the locked content.
Before you finish, test the form yourself. Fill in every field type to make sure they work as expected. Check that dropdown lists show all options, that date fields accept the format you intended, and that required fields actually stop submission if left blank (if you set them as required).
Saving and sharing your completed form
Save your form as a PDF. Go to File > Save As and choose PDF as the format. Name it clearly — something like "Customer Feedback Form" or "Job process 2024" — so people know what it is.
You can now share the form by email, upload it to a website, or print it. People who receive it can open it in Adobe Reader (free), any web browser, or Acrobat Pro and fill in the fields. When they save their filled-out copy, their answers stay in the file.
If you want to collect responses centrally, Acrobat Pro can compile filled forms into a spreadsheet. Ask people to email you their completed forms, then go to Tools > Prepare Form > Responses > Collect Data from Multiple Forms. Acrobat reads all the responses and exports them to a CSV file you can open in Excel or Google Sheets.
Common issues and how to fix them
If fields do not line up with your form content, select the field and drag it into position. If a field is too small for the text people will enter, resize it by dragging the corner handles. If a dropdown list is too short to show all options, make the box taller.
If people report that they cannot type in a field, check that the field type is set to "Text" and not "Read Only". Select the field, open properties, and verify the type. If a date field rejects valid dates, check the date format in the field properties — it may expect MM/DD/YYYY but you set it to DD/MM/YYYY.
If you need to make changes after sharing the form, open the original PDF in Acrobat Pro, edit the fields, and save it. Send the updated version to anyone who has not yet filled it out. People who already filled out the old version will need to use the new one if you made significant changes.
Frequently Asked Questions
Can people fill out my form on a phone or tablet?
Yes. Adobe Reader is available for iOS and Android, and most web browsers on phones can open and fill PDFs. The form will reflow to fit the smaller screen. Test it on a phone before you send it out to make sure fields are still clickable and readable at that size.
What if I do not have Adobe Acrobat Pro?
Acrobat Pro is the standard tool for creating fillable forms in Adobe. Free alternatives like PDFtk or Smallpdf can add basic fields, but they have fewer options and less control over formatting. If you only need a straightforward form with a few text boxes, those tools may work. For complex forms, Acrobat Pro is worth the cost.
Can I require people to fill in certain fields before they submit?
Yes. Select a field, open its properties, and check the "Required" box. If you add a Submit button to your form, people cannot submit until all required fields have content. Without a Submit button, the form just prevents saving until required fields are complete.
How do I add a signature field?
Click the Signature field tool in the Prepare Form toolbar, then draw a box where you want the signature to go. When someone opens the form, they can click that box and sign using their mouse, trackpad, or touchscreen. The signature is embedded in the PDF they save.
Can I see what people entered in my form?
Yes, if they email you the filled-out PDF. Open it in Acrobat Pro and you will see all their answers. If you set up response collection, Acrobat can compile multiple responses into a spreadsheet automatically. Otherwise, you have to open each form individually to review answers.
