Download the completed form
When all fields are filled, click Download to save the completed PDF with all your entries embedded permanently.
Types of PDF Form Fields
Modern interactive PDF forms use several types of fields:
Text fields: The most common type. Click and type your name, address, or other information.
Checkboxes: Click to check or uncheck. Used for yes/no questions and multi-select options.
Radio buttons: Select one option from a group. Clicking one automatically deselects others in the same group.
Dropdown menus: Click to reveal a list of options, then select one.
Date fields: Some forms have special date pickers or auto-format text fields.
What If the PDF Isn't Fillable?
Not all PDFs are interactive forms — many are just flat documents printed to PDF. If you need to fill out a form that has no interactive fields:
Option 1: Use PDFBro's Edit PDF tool to add text annotations over the blank lines where you'd write your information.
Option 2: Use the Sign PDF tool to add a signature element, then combine with text annotations from Edit PDF.
This technique works for most printed-form-style PDFs that were never designed as interactive.
Pro Tips
- 1
Use Tab key to move between form fields sequentially — much faster than clicking each one.
- 2
If a form has a 'Reset' button, avoid clicking it — it will clear all your entries.
- 3
After downloading, reopen in a PDF viewer to verify all fields saved correctly before submitting.
Frequently Asked Questions
Can I fill out any PDF form for free?
Interactive PDF forms (with form fields) can be filled for free on PDFBro. Non-interactive 'flat' PDFs require using the annotation tools to place text over blank lines.
Can I add a signature to a filled form?
Yes. Use PDFBro's Sign PDF tool after filling the form, or use the signature field if one exists in the form.
Are my form entries saved when I close the browser?
No. If you close the browser before downloading, your entries will be lost. Always download before closing.
