- Product
- PowerPoint for Android
- Device & OS
- Android
- Scenario
- Inserting a PNG image with a transparent background into a presentation slide on an Android device.

Update the App and Submit Feedback to Microsoft
Since this is a known rendering bug in specific builds of the Android app, checking for the latest updates or reporting it directly to the developers is the recommended approach.
Microsoft support agents have reproduced this issue on specific versions, such as version 1.0.1 (16.0.14026.20298). If a permanent fix hasn't been rolled out to your device yet, providing your exact device details helps expedite the patch.
Open the Google Play Store on your Android device, search for Microsoft PowerPoint, and tap 'Update' if a newer version is available.
Open the PowerPoint app, navigate to Settings, and check your current version number to see if you are running the affected build.
Tap your profile icon or navigate to the 'Help & Feedback' section within the app. Select 'Send Feedback' to report the bug, including your device model and app version.
Insert the PNG Using PowerPoint Web or Desktop
Bypass the Android app's rendering limitations by inserting your transparent images using the desktop or web version of the software.
Use WPS Office to Seamlessly Handle Transparent Images on Android
If PowerPoint for Android keeps ruining your transparent PNGs with black backgrounds, switch to WPS Office. It flawlessly renders transparent images on mobile, ensuring your slides look professional without any frustrating bugs.
- 1. Download WPS Office: Install the free WPS Office app from the Google Play Store on your Android device.
- 2. Open your presentation: Locate and open your existing .pptx file directly within the WPS Office app.
- 3. Insert the PNG image: Tap 'Insert', choose 'Picture', and add your transparent PNG to the slide. The background will remain completely transparent.
Frequently Asked Questions
Why do transparent backgrounds turn black in mobile presentation apps?
This usually happens due to a rendering bug or a lack of proper alpha-channel support in specific versions of the mobile app. Instead of processing the transparency, the app defaults to filling the empty pixels with black.
Can I remove the black background directly inside the Android app?
Mobile presentation apps have limited image editing features compared to their desktop counterparts. The 'Remove Background' tool is typically unavailable or ineffective for fixing this specific glitch on a smartphone or tablet.
How can I check if my PNG actually has a transparent background?
Open the image in your phone's default gallery app. If the background automatically adapts to the app's dark or light theme (showing black or white depending on your system settings), or if it displays a checkerboard pattern, the background is transparent.
Does converting the PNG to another format fix the issue?
Sometimes converting the PNG to an SVG (Scalable Vector Graphics) file can bypass the rendering bug, as mobile apps handle vector transparency differently than raster images.
