How to Fill Out a PDF Form on iPhone
You received a PDF form on your iPhone — a rental application, a consent form, or a tax document — and you need to fill it out now. The iOS Files app can display PDFs but cannot fill form fields. Most PDF apps on the App Store either cost money or require an account.
YourPDF.tools works directly in Safari on your iPhone. Open the fill tool, load your PDF, tap to fill in form fields, and save the completed document — no app installation required.
Key Takeaways
- •No app installation needed — works in Safari on iPhone.
- •Supports fillable PDF form fields (text boxes, checkboxes, dropdowns).
- •Your PDF is processed on your iPhone — nothing is uploaded.
- •Save or share the completed form directly from Safari.
