Supports PDF files up to 10MB
Sign your PDF in seconds — no registration, no downloads
Android users have a seemingly endless number of PDF signing apps available on the Google Play Store, but most of them share the same frustrating problems: intrusive ads, aggressive subscription prompts, unnecessary permissions, and cluttered interfaces that make a simple task complicated. The best way to sign PDFs on Android in 2026 is to skip the Play Store entirely and use SignMyPDF directly in your Chrome or Samsung Internet browser — no download, no account, and no subscription required.
Why Browser-Based Signing Beats Android PDF Apps
The typical free PDF signing app on the Play Store is free in name only. Within seconds of opening it, you encounter either a banner ad, a pop-up asking you to start a free trial, or a paywall that blocks the features you actually need. The business model of most free apps is to get you to install them and then pressure you into subscribing — PDF signing apps are no exception.
Beyond the monetization tactics, many Android PDF apps request permissions that raise legitimate privacy concerns. Why would a PDF signing app need access to your contacts? Or your call logs? Or your camera in a way that is always active rather than just when you are using it to capture a signature? These permissions are requested either for advertising targeting or for data collection that you never explicitly agreed to.
SignMyPDF requires no installation and therefore no permissions. You visit the website in Chrome, the browser handles everything using its built-in JavaScript engine, and your PDF never leaves your Android device. The process is faster than installing an app and significantly more private.
How to Sign a PDF on Android: Step by Step
Launch Chrome, Samsung Internet, Firefox, or Edge on your Android phone. All major Android browsers are fully compatible with SignMyPDF. Navigate to signmypdf.io.
Tap "Choose PDF File" to open your device's file picker. You can select a PDF from your Downloads folder, Google Drive, internal storage, or any cloud storage app you have installed. If you received the PDF as an email attachment in Gmail, open the attachment, tap the share icon, and select "Open in Chrome" to bring it directly into SignMyPDF.
Draw with your finger: Tap the "Draw" tab and sign using your finger on the touchscreen. For Android phones, landscape orientation generally gives you the best results because you have more horizontal space to work with. Draw slowly for a natural-looking result.
Type your name: Tap "Type," enter your name on the keyboard, and select a signature font. This takes about 10 seconds and works particularly well on small phone screens where drawing can be challenging.
Tap the document at the location where you need to sign. Drag your signature to the correct position and resize it using the corner handle. Android touch screens handle this process smoothly in all major browsers.
Tap the download button. On Android, the signed PDF saves to your Downloads folder. From there you can open it in any PDF viewer, email it directly, share it via WhatsApp or Google Drive, or upload it anywhere using the standard Android share menu.

Android-Specific Tips
S Pen users: If you have a Samsung Galaxy device with an S Pen stylus, use it to draw your signature in SignMyPDF. The precision of the S Pen on a large Android screen produces signatures that are genuinely indistinguishable from actual pen signatures.
Landscape mode: Almost all Android phones benefit from landscape orientation when drawing signatures. The wider canvas gives you room to create a natural signature without feeling cramped.
Add to home screen: You can add signmypdf.io to your Android home screen directly from Chrome (tap the three-dot menu and select "Add to Home screen"). This makes it accessible as quickly as any app, without any installation.
Google Drive integration: If the PDF you need to sign is stored in Google Drive, you can open it in SignMyPDF by selecting it from the file picker's Drive integration. After signing, save the file back to Drive for easy access and sharing.
WhatsApp documents: Many people in the US and internationally receive documents via WhatsApp. To sign a WhatsApp PDF, tap the document to download it, then open SignMyPDF in Chrome, tap Choose File, and navigate to the downloaded file in your Downloads folder.
