Question details
Users want to know how to insert stamps and digital signatures into PDF documents using the Adobe Acrobat mobile app.
- Product
- Adobe Acrobat
- Device & OS
- Mobile Device
- Scenario
- Reviewing and approving PDF documents on a smartphone or tablet while away from a computer.
- Observed behavior
- The mobile app does not display or support the standard desktop stamping features, preventing users from fully authenticating documents on the go.
Ensure that you have access to a desktop computer with Adobe Acrobat installed, as the stamp feature is currently restricted on the mobile version.
Use Acrobat Desktop for Stamps and Mobile for Signatures
Since Adobe Acrobat's mobile app lacks the desktop stamp feature, you must apply stamps on your computer before signing on your mobile device.
Adobe Acrobat restricts certain advanced annotation features, such as custom and dynamic stamps, to its desktop application. To complete a document requiring both a stamp and a signature, you will need to utilize a cross-device workflow using Adobe Document Cloud.
Launch the Adobe Acrobat desktop application on your Windows or Mac computer and open the PDF document you need to process.
Navigate to the 'Tools' menu, select 'Stamp', and choose the appropriate custom or dynamic stamp to place onto your document.
Save the stamped document directly to Adobe Document Cloud (or another cloud storage service like Google Drive) so it syncs with your mobile device.
Open the Adobe Acrobat app on your mobile device, locate the recently synced PDF, tap the pencil icon, and use the 'Fill & Sign' tool to draw or place your signature.
Easily Sign and Annotate PDFs on Mobile with WPS Office
Avoid cross-device limitations. WPS Office provides a powerful, all-in-one PDF reader and editor that lets you easily manage, sign, and annotate PDF documents directly from your smartphone, tablet, or PC.
- 1. Download the WPS Office app: Install and open the WPS Office application on your iOS or Android mobile device.
- 2. Open your PDF: Locate and open your PDF document within the WPS PDF viewer.
- 3. Access signature tools: Tap on the 'Tools' icon at the bottom of the screen and select the 'Fill & Sign' or 'Annotation' option.
- 4. Create and place your signature: Tap 'Create Signature' to draw your signature on the screen, then drag and drop it to the desired location on the PDF page.
- 5. Save and share: Tap the 'Done' or 'Save' button in the top corner to apply your changes, then share the finalized PDF directly from your phone.
