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 Share.
  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.
