Sign Documents on Android

Sign documents quickly on your Android device using pdfFiller.

What is the Signature Tool?

The signature tool in pdfFiller allows you to sign documents on Android easily. This self-signing feature enables you to add your signature directly to documents without needing to send them out for signature. You can access this tool via the Signature button, making it straightforward to use. It is fully compatible with Android devices, ensuring that you can sign documents anytime, anywhere. Unlike complex software, pdfFiller focuses on a simple self-signing process that anyone can navigate.

How Does This Feature Improve Your Workflow?

The signature tool significantly enhances your document management by eliminating the need for printing and scanning. This feature speeds up document turnaround time, allowing you to work from any location. It's particularly beneficial for small businesses that require quick and efficient signing processes. By using pdfFiller, you can ensure that your workflow remains uninterrupted and efficient.

Three Ways to Create Your Signature

With pdfFiller, you can sign documents on Android using three different methods to create your signature: draw, type, or upload your signature image. Each method is legally binding, so you can choose the one that best suits your convenience. All options are compatible with Android devices, making it easy to sign documents on the go.

How to Draw Your Signature

  • Open the signature tool and select the draw option.
  • Use your finger, stylus, or mouse to create your signature on the screen.
  • Adjust the color and thickness of your signature as desired.
  • Resize your signature after placement to fit the document appropriately.
  • This method is applicable for all document types, ensuring versatility.

How to Type Your Signature

  • Select the typing option in the signature tool.
  • Choose your preferred font style and color for your signature.
  • Type your name in the designated area.
  • Adjust and reposition your typed signature easily on the document.
  • This method is legally binding, just like drawing your signature.

Uploading Your Signature Image

  • Click on the upload option in the signature tool.
  • Select an image file of your signature from your device.
  • Ensure the image is in a supported format, such as PNG or JPEG.
  • Follow the prompts to upload your signature image to the document.
  • Your uploaded signature is legally binding and works on Android devices.

Adding Your Initials

You can add initials to documents using the same three methods available for signatures. Initials can be resized to fit the document layout and are legally binding, just like full signatures. This feature is applicable for various documents, ensuring that your initials carry the same weight as your signature.

Customizing Your Signature

pdfFiller allows you to customize your signature's appearance by changing the font, color, and thickness. You can resize and reposition your signature to enhance its visibility on the document. These customization options are available for all methods of signature creation, helping to enhance the professionalism of your documents.

Saving and Reusing Signatures

Once you create your signature, it is saved to your pdfFiller account for future use. You can set a default signature for quick access when signing future documents. This feature is ideal for frequent signers, making the process even more efficient.

Legal Validity of Signatures

Signatures created using pdfFiller are compliant with the ESIGN and UETA acts, ensuring their legal validity. Each signature comes with a timestamped audit trail, and a verified pdfFiller badge is included. This guarantees that your signatures are legally binding across jurisdictions, providing peace of mind when signing important documents.

Next Steps After Signing

After signing documents, you can easily share them with others. pdfFiller integrates with other features, allowing you to streamline your document workflow. This is particularly beneficial for small business needs, as it connects the signing process to broader functionalities within the platform.

How Does pdfFiller Compare?

When comparing pdfFiller to DocuSign, pdfFiller offers a more user-friendly interface for small and medium-sized businesses. While DocuSign may have more advanced features, it comes at a higher cost.

In contrast to Adobe Acrobat Sign, pdfFiller provides a simpler signing process without the need for complex setups. Adobe may be better suited for larger enterprises needing extensive integrations.

Lastly, when looking at signNow, pdfFiller includes over 1 million templates for quick document creation, whereas signNow may offer lower pricing but lacks the same variety of templates.
