All the ways to digitally sign a PDF

Digital signatures are now a common alternative to paper-based signatures, especially with the rise of cloud computing. This guide shows you how to easily add a digital signature to your PDF documents across various operating systems and platforms.

Signing PDFs on Windows

Windows users can leverage the built-in capabilities of Microsoft Edge. Open your PDF in Edge (either by dragging and dropping or using Ctrl O). A drawing toolbar will appear. Select the pen tool, choose your preferred color and line thickness, then sign using your mouse, trackpad, or touchscreen. To correct mistakes, use the eraser tool. Save your signed document by clicking the save icon (floppy disk) – choose to overwrite the original or save as a new file.

Signing PDFs on macOS

macOS users can utilize Preview. Open your PDF in Preview (double-click or use Spotlight search). Locate the signature icon in the toolbar (or go to View > Show Markup Toolbar). Click "Create Signature" and choose your preferred method: drawing on your trackpad, using your webcam to capture a paper signature, or signing with your finger or Apple Pencil on a linked device. Once finished, click "Done," reposition, and resize as needed. Your signature is automatically saved for future use. Save your changes using File > Save (to overwrite) or File > Export (to create a new file).

Signing PDFs on Android

Android users can conveniently sign PDFs using Google Drive. Open your PDF in Google Drive, tap the edit button (pen icon), select the pen tool, and choose your color and line thickness. Sign directly on the document. Use the eraser or undo button to correct errors. Save by tapping "Save" (to overwrite) or the three dots and "Save copy" (to create a new file). Alternatively, explore third-party apps like Adobe Fill & Sign or JetSign for additional features.

Signing PDFs on iOS or iPadOS

iOS and iPadOS offer similar functionality to macOS, using the Files app. Open your PDF, tap the pen icon, and choose an existing signature or create a new one using your finger or Apple Pencil. Reposition and resize as needed. Tap "Done" to overwrite or tap the filename and "Duplicate" for a separate copy. Third-party apps like PDF Expert or SignNow provide extra features.

Additional PDF Signing Options

For broader options, consider Dropbox, which allows signing PDFs directly in your web browser. DocuSign offers robust features, including signature management and tracking for multiple signers. ILovePDF provides a simple browser-based solution for various PDF tasks, including signing. Choose the method that best suits your needs and workflow.
