How to Sign PDF Forms More Easily on a Tablet
Question details
The user needs a smoother way to sign PDF forms on a tablet without signature interruptions caused by lifting a finger or double-tapping requirements in older PDF applications.

- Product
- Adobe Reader XI / PDF Applications
- Device & OS
- iOS, Android, or Windows tablet
- Scenario
- Signing a PDF form using touch input on a tablet device.
- Observed behavior
- The application requires double-tapping to sign, and the signature stroke breaks or completes prematurely if the user lifts their finger while writing.
Ensure your tablet's touch screen is clean and verify if your specific device requires palm-rejection settings to be enabled for optimal drawing performance before attempting to sign.
Update Your PDF Reader and Use the Fill & Sign Tool
Updating to the latest version of your PDF reader ensures you have the most recent touch-friendly enhancements designed specifically for tablet signatures.
Older software versions like Adobe Reader XI were primarily optimized for desktop use. Modern versions of PDF applications feature dedicated signature tools that properly handle multi-stroke touch inputs without requiring a double-tap.
Open your tablet's app store (Apple App Store, Google Play Store, or Microsoft Store) and update your PDF application to the latest version.
Launch the updated PDF application, open your form, and tap on the 'Fill & Sign' tool instead of the basic drawing or pen tools.
Select the signature icon to open the drawing pad. Draw your complete signature smoothly, then tap 'Save' or 'Done'. You can now apply this signature with a single tap in the future.

Use a Compatible Active Stylus
Using a stylus can prevent the palm-rejection or multi-touch confusion that causes signature breaks when your hand rests on the screen.
Use WPS Office for Seamless PDF Signing on Tablets
WPS Office provides a highly responsive PDF editor for iOS, Android, and Windows tablets. Its dedicated PDF signature tool allows you to easily draw, save, and insert signatures with a single tap, eliminating touchscreen glitches commonly found in older software.
- 1. Download WPS Office: Install WPS Office from your tablet's app store and open the application.
- 2. Open your PDF form: Locate and open your PDF document within the WPS Office file manager.
- 3. Access the Signature tool: Tap on the 'Tools' menu at the bottom or top of the screen, navigate to the 'PDF Edit' or 'Annotation' tab, and select 'Signature'.
- 4. Draw your signature: Use your finger or stylus to draw your signature continuously on the popup pad; WPS will smoothly capture your handwriting even if you lift your finger between letters.
- 5. Place and resize: Tap 'Done' to place the signature on the document. You can easily drag it to the correct signature line and resize it as needed.

Frequently Asked Questions
Why does my signature break when I lift my finger in older PDF apps?
Older PDF applications, like Adobe Reader XI, often process a finger lift as the end of a drawing stroke. Updating to modern PDF editors provides a continuous drawing mode designed specifically for multi-stroke signatures.
Can I save my signature so I don't have to draw it every time?
Yes, most modern PDF applications, including WPS Office and the latest Acrobat Reader, allow you to draw your signature once, save it securely within the app, and insert it into future forms with a single tap.
Do I need a special stylus to sign a PDF on a tablet?
While a standard capacitive finger touch works fine for basic signing, using an active stylus provides better precision and palm rejection. This allows you to rest your hand on the screen naturally, resulting in a cleaner and more professional-looking signature.
