How to Sign a PDF on Android for Free (No App Needed)
Your phone buzzes. It's an urgent email: "Please sign this contract ASAP."
You're at lunch, or on the bus, and all you have is your Android phone. You search the Play Store, but every app wants you to create an account, start a 7-day trial, or pay $9.99/month just to sign one single page.
There is a better way. You don't need an app to sign PDFs on Android.
Here is the fastest, completely free way to e-sign documents on any Android device (Samsung, Pixel, OnePlus, and more) using just your Chrome browser.
📱 The Problem with "Free" E-Sign Apps
Most "PDF Filler" or "Sign" apps on the Google Play Store follow a confusing pattern:
- Huge Downloads: They take up 50MB-100MB of space.
- Account Forced: You typically can't do anything without signing up.
- The "Free" Trap: You edit your document, but when you hit "Save" or "Send," a paywall pops up asking for a subscription.
Inkless is different. It's a web-based tool, meaning it works right inside Chrome, Firefox, or Brave on your Android phone.
⚡ Step-by-Step: How to Sign on Android
Follow these steps to sign and send a document in under 60 seconds.
Step 1: Open Your Browser
Open Chrome (or your preferred browser) on your Android device and navigate to useinkless.com.
Step 2: Upload Document
Tap the "Upload PDF" button. You can select a file from your:
- Required Downloads folder
- Google Drive
- Dropbox
- Or directly from your email attachments
Step 3: Add Your Signature
Once uploaded, the mobile-friendly editor will load.
- Tap the "Signature" tool in the toolbar.
- Draw your signature with your finger on the screen. (It's actually easier on a touchscreen than a mouse!)
- Drag the signature to the correct line on the document.
Tip: You can also add Text fields for your Name, Date, or Address.
Step 4: Finish & Download
Tap "Finish". You can now:
- Download the signed PDF to your phone.
- Email it directly to your boss or client.
🛠 Why This is Better Than Native Apps
- Zero Storage Space: No 100MB app to install.
- No Updates Required: You always use the latest version.
- Works on OLD Phones: As long as you have a web browser, it works. No need for the latest Android OS.
- Actually Free: We don't bait-and-switch you at the download screen.
🔒 Is it Safe?
Yes. Even though you are using a browser, Inkless uses bank-grade AES-256 encryption. Your connection is secure (HTTPS), and your documents are processed with strict privacy standards. It is just as secure—and often more secure—than random apps from unknown developers in the Play Store.
🏁 Conclusion
Next time you need to sign a permission slip, lease, or waiver on your Android phone, skip the Play Store search.
Just open your browser, go to Inkless, and you're done.
