How to Sign a PDF on Android
Sign a PDF on your Android phone in minutes using your browser on sign.pink. No app to install, no account to create. Tap to sign and finish on mobile.
You do not need a special app to sign a PDF on Android. If someone sent you a document through sign.pink, you can open it, read it, and sign it right in your phone's browser, whether that is Chrome, Firefox, or Samsung Internet. As a signer, you do not need to create an account or pay anything. You just follow the secure link that was sent to your email or phone, sign with your fingertip, and you are done. When the document is completed, sign.pink captures a tamper-evident audit trail so everyone can see who signed and when.
- 1
Open the signing link
Tap the secure link in the email or text message that invited you to sign. It opens directly in your Android browser, so there is nothing to download or install.
- 2
Agree to sign electronically
Before you start, confirm that you agree to use electronic records and signatures for this transaction. You may also be asked to enter a one-time verification code sent to your email or phone so the platform can confirm it is you.

Read the document
Scroll through the PDF on your screen. Pinch to zoom in on any section, or rotate your phone to landscape, so you can read the full terms before you agree to anything.

Tap a signature field and sign
Tap a highlighted signature field to start. Sign with your fingertip on the touchscreen, or switch to type your name and pick a signature style. You can clear it and try again until it looks right, then adopt it.

Add dates, initials, and other fields
Fill in any remaining fields the sender requested, such as the date, your initials, a checkbox, or a text box. Each required field is marked, and sign.pink can jump you to the next one so you do not miss anything.
