Let’s get started!
Step 1. Visit the PDFgear online signer and tap “Select PDF file” to upload the PDF you want to sign.
Step 2. Click the “Add or Edit Annotations” icon from the upper-right sidebar, then select the “Pen” icon and choose “ADD SIGNATURE”.
Step 3. Choose one of the three signature options:
Check “Save Signature” for future use, tap “Create”, and adjust the signature’s position and size as needed.
Step 4. Tap “Download” in the top-right corner to save the signed PDF.
Compared to the PDFgear Android app, the online signer supports only four fonts for typed signatures and doesn’t allow taking a real-time photo of your handwritten signature.
Samsung Notes is a familiar app for Samsung users, pre-installed on most Galaxy devices. It allows you to annotate and sign PDFs directly on your Samsung phone or tablet.
Follow these steps to sign a PDF on Samsung phones:
Step 1. Open the Samsung Notes app on your phone or tablet.
Step 2. Tap the “Add PDF” icon to load the PDF you want to sign.
Step 3. Go to the page you want to sign, tap the “Pen” tool in the lower-left corner, and draw your signature using your finger or stylus. Adjust its size or position as needed.
Step 4. Tap the Three Dots at the top left, select “Save as file,” choose “PDF file,” rename the file, and save it.
Signatures added with Samsung Notes are treated as annotations, which means they can be easily removed.
For better security, try PDFgear for Android. It can flatten signatures, permanently embedding them into the PDF to make them tamper-proof and secure.
If you cannot add your signature, it may be due to using an incompatible PDF viewer or not having the necessary permissions in the app. Ensure you’re using an app specifically designed for filling and signing PDFs and that you have opened the document in edit mode.
PDFgear for Android allows you to save your signature for future use. After creating your signature within the app, it can typically be stored and reused in subsequent documents without needing to recreate it each time.
No, an internet connection is not required to sign a PDF when using the PDFgear Android app. Simply open your PDF in PDFgear, click Edit, select Fill & Sign, create your signature, and place it in the PDF. For detailed steps and screenshots, refer to Method 1.
No matter which Android phone or tablet you use, PDFgear offers a fast and free solution for signing PDFs. To ensure the security of your signature, PDFgear can flatten and embed it into the PDF, both online and offline, making it tamper-proof and difficult to remove.
