Use the Signature Tool to Insert an Image as a Stamp

Since Acrobat Reader for Android lacks a native stamp tool, you can utilize the image upload option within the Signature feature to place your visual mark.

The dedicated stamp tool found on the desktop version of Acrobat is currently unsupported on the Android app. However, you can bypass this limitation by importing an image through the app's 'Fill & Sign' signature tool, which allows you to place custom graphics exactly like a stamp.

Open the PDF document

Launch the Acrobat Reader app on your Android device and open the PDF file you wish to modify.

Access the Fill & Sign tool

Tap the blue pencil icon located in the bottom right corner of the screen to open the edit menu, then select 'Fill & Sign'.

Initiate signature creation

Tap the fountain pen icon on the bottom toolbar. Select 'Create Signature'. If a signature already exists there, you must tap the minus (-) icon next to it to clear it first.

Import your stamp image

On the signature creation screen, tap the 'Image' icon to browse your device's photo gallery. Select the image you want to use as your custom stamp.

Place the stamp on your PDF

Adjust the image cropping if prompted, and tap 'Done'. Finally, tap anywhere on your PDF document to drop the image in place. You can drag the corners to resize it as needed.

Use the Signature Tool to Insert an Image as a Stamp

Use Transparent Images: For the most professional look, use a PNG image with a transparent background so your custom stamp does not block the underlying document text.

Frequently Asked Questions

Can I use multiple different stamps in the Acrobat Reader Android app?

Because this workaround relies on the signature tool, you can only store one primary signature and one initial at a time. To use a completely different stamp image, you will need to delete the current image signature and upload the new one.

Why does my custom stamp have a solid white background?

This usually happens if your source image is saved as a JPG, which does not support transparent backgrounds. To fix this, use an external image editor or background removal tool to save your stamp file as a PNG with transparency before importing it.

Will Adobe add a native stamp feature to the Android app?

While Adobe frequently updates its mobile applications, there is currently no official timeline for adding the desktop stamp tool to the Android version. Utilizing the signature image workaround remains the most effective native method.
