Sign on Android

Sign documents quickly on your Android device using pdfFiller's intuitive tools.

What is the Signature Tool?

The signature tool allows you to sign on Android devices easily and efficiently. It is designed for self-signing, which means you can sign documents without needing to send them to someone else for approval. This distinction is crucial for small and medium businesses that often require quick turnaround times for document signing. The tool offers various signing methods, including drawing, typing, and uploading an image of your signature. With a user-friendly interface, it simplifies the process of signing documents, making it accessible for everyone, regardless of technical skill.

How Does This Feature Improve Workflow?

Traditional signing methods can often lead to delays, especially when documents need to be printed, signed, and then scanned back into digital format. These common issues can slow down workflows significantly. By utilizing the sign on Android feature, small and medium businesses can benefit from digital signatures that are not only faster but also legally binding. This feature saves time by allowing users to sign documents directly on their devices, eliminating the need for physical paperwork and reducing the chances of errors in the signing process.

Three Ways to Create Your Signature

Creating a signature on your Android device is flexible and user-friendly. Here are three methods you can use:

  • Draw your signature using your finger or a stylus. This method allows for a personal touch and is straightforward.
  • Type your signature using the keyboard. You can choose from various font styles and colors to customize your signature.
  • Upload an image of your handwritten signature. This option is great for those who prefer their physical signature's look and feel.

All these methods are legally equivalent, ensuring that your signature holds up in any legal context. Choose the method that best fits your preferences for signature creation.

How to Draw Your Signature

Follow these steps to draw your signature on your Android device:

  • Open the pdfFiller app on your Android device.
  • Select the document you want to sign.
  • Tap on the signature field where you want to add your signature.
  • Choose the option to draw your signature.
  • Use your finger or a stylus to draw your signature on the screen.
  • Customize your drawing by adjusting the thickness or color if options are available.
  • Once satisfied, save your signature to the document.
  • Review the placement to ensure it is clear and legible.

Using a stylus can provide better precision, and practicing your signature can lead to better results.

How to Type Your Signature

To type your signature, follow these steps:

  • Open the pdfFiller app and select the document you wish to sign.
  • Tap on the signature field to begin.
  • Select the option to type your signature.
  • Choose your preferred font style from the available options.
  • Customize the color and size of the text to match your preferences.
  • Type your name or initials in the designated area.
  • Review the typed signature for clarity and legibility.
  • Save the signature to the document once you are satisfied.

Typed signatures are legally valid and can be customized to reflect your personal style.

How to Upload Your Signature Image

To upload a signature image, follow these instructions:

  • Open the pdfFiller app on your Android device.
  • Select the document that requires your signature.
  • Tap on the signature field where you want to place your signature.
  • Choose the option to upload an image of your signature.
  • Select the image file from your device's storage. Supported formats typically include PNG and JPEG.
  • Adjust the size and placement of the signature image as needed.
  • Ensure the image quality is high for clarity.
  • Save the document with your uploaded signature.

Using a high-quality image ensures that your signature appears professional and clear.

Adding Initials to Your Document

To add initials to your document, you can use the following methods:

  • Draw your initials using the drawing tool, similar to signing your full signature.
  • Type your initials using the keyboard, selecting a font that matches your signature style.
  • Upload an image of your initials if you prefer a handwritten look.

When placing your initials, ensure they are clear and positioned correctly to avoid confusion.

Saving and Reusing Your Signatures

To save and reuse your signatures, follow these steps:

  • After signing a document, tap on the option to save your signature in your account.
  • Set a default signature if you frequently use one particular style.
  • Access your saved signatures anytime you need to sign a new document.
  • Reusing signatures speeds up the signing process for future documents.

This feature is particularly beneficial for small and medium businesses that handle numerous documents regularly.

Legal Validity of Your Signatures

Understanding the legal compliance of your signatures is essential. The signatures created using pdfFiller comply with various regulations, including ESIGN, UETA, eIDAS, and GDPR. These laws ensure that digital signatures are recognized as legally binding. Additionally, maintaining an audit trail of signed documents enhances their validity. The verification process for signed documents is straightforward, ensuring that all parties can trust the authenticity of the signatures.

A Superb App to Create Fillable PDF Forms The most easiest app to create fillable pdf forms in the most efficient way. Furthermore, editing an existing pdf is so much easier with super features such as text editing, adding watermark, merging and splitting pdf files, etc. This is a paid application. Editor interface is not that simple and you need more time to learn for the beginne

Outstanding Functionality & Customer Service I tried several pdf editors in my search to save time filling out real estate forms. I was blown away when using the editor for the first time and I inadvertently closed my browser, all of my edits were saved and waiting for me when I returned to the site - even before creating a user account! Now that's nice! Not only was pdfFiller miles ahead in its functionality and user-friendliness, when I cancelled my subscription because I no longer had the need - my money was refunded instantly and without question. This level of customer care is rare and worthy of celebration. Congrats pdfFiller and Thank you for an outstanding product and customer service!
