I have a Power Automate action that requires an image in base64. Is there a way to convert a given image to base64 using Flow via an action or Expression builder?

I know this has been a while, but wanted to respond in case you needed it. The contentBytes is indeed the base64 for your image. i.e. to view it you could enter it as a data URI for an image as data URI with the format data:[contentType]/[format];base64,{contentBytes} so for your png image:

"data&colon;image/png;base64,{contentBytes}"

Hey Mate @jokanol1

You can use the Expression - base64(<your file content>)

If you are getting content from a SharePoint the you direct convert it - using the formula -

outputs('Get_file_content_using_path')?['body']?['$content']
