- Product
- Adobe Acrobat Mobile App
- Device & OS
- iPadOS / Mobile
- Scenario
- Reviewing and annotating PDF drawings and documents while on the go using a mobile device.
- Observed behavior
- The mobile version of Adobe Acrobat provides limited commenting features compared to the desktop version, lacking full support for some advanced drawing tools and custom stamp workflows.
Ensure your mobile operating system is fully updated and check if your current PDF application requires you to sign in with a premium subscription to unlock advanced annotation tools.
Utilize Acrobat Mobile Premium Features and Desktop Workarounds
Access the available markup tools in the mobile app via a premium subscription, and use remote desktop access for advanced features.
While the Adobe Acrobat mobile app does not completely mirror the exact desktop Acrobat Pro toolset, it does provide essential commenting and markup features when logged in with an eligible subscription. For complex reviews, transitioning to a desktop environment or using remote access may be required.
Download and install the latest version of Adobe Acrobat from the Apple App Store or Google Play Store to ensure all latest features are available.
Log in with an Adobe ID linked to an active Acrobat Pro subscription to unlock premium editing, commenting, and markup tools.
Open your PDF document, tap the pencil (Edit/Comment) icon, and select the available drawing tools such as the highlighter, freehand pen, and basic geometric shapes.
For highly custom stamps or complex drawing tools unavailable natively on mobile, open the document in Acrobat Desktop on a PC or Mac, or use a remote-access application on your iPad to control your desktop workstation.

Use WPS Office for Comprehensive PDF Markup on Mobile
WPS Office provides a highly capable mobile PDF editor that makes document reviewing seamless. You can easily add freehand drawings, geometric shapes, text comments, and stamps to your PDFs directly from your iPad or mobile device without needing a desktop.
- 1. Install WPS Office Mobile: Download the free WPS Office app from the App Store for your iPad/iPhone or from the Google Play Store for Android devices.
- 2. Open Your PDF Drawing: Launch the WPS Office app, navigate to your files, and tap on the PDF document you need to review.
- 3. Access Annotation Tools: Tap on the 'Tools' menu at the bottom of the screen, select the 'Annotation' tab, and choose 'Pen' for freehand drawing or 'Shape' to insert circles and rectangles.
- 4. Apply Stamps: While in the Annotation menu, select the 'Stamp' tool to insert predefined review stamps directly onto the specific areas of your drawing.

Frequently Asked Questions
Can I create custom stamps on a mobile PDF app?
Custom stamp creation is generally limited to desktop PDF editors like Acrobat Pro. Mobile apps usually provide a set of standard, predefined stamps for quick reviews. However, you can insert custom images as a workaround for stamps on many mobile PDF apps.
Why are my drawing tools missing in my mobile PDF viewer?
Many mobile PDF viewer applications are designed for reading only and hide editing tools by default. To access markup and drawing tools, ensure you switch to 'Edit' or 'Comment' mode, and verify that your app subscription is active if using a premium service.
Are iPad PDF annotations visible when opened on a desktop PC?
Yes, standard annotations such as geometric shapes, freehand drawings, and text highlights are embedded into the PDF file structure. They will be fully visible and editable when the document is opened in compatible desktop software like Adobe Acrobat or WPS Office.
