Use PNGs to identify the creative source

Use the following guidelines to ensure that your image can be used to accurately identify creative sources:

• Upload an original PNG file
• Don’t modify the screenshot after it was taken. However, you can crop the screenshot to the ad as long as the entire ad is still visible.
• Don’t convert an image to PNG (i.e. saving a JPG as a PNG)

Screenshots taken on Android devices are automatically saved as PNG.

For screenshots taken on iOS devices, use the following steps to save as a PNG:

1. Take a screenshot.
2. Click Save to photos.
3. Open the Photos app and click on the screenshot.
4. On the screenshot, click .
5. Select the mail app.
6. Send the image to yourself and select Actual Size for the image size, which will send the image as a PNG. Sending sizes other than Actual Size will send as JPG.
