Turn an iPhone photo into a PNG for apps and sites that ask for one. Rename the file in Finder and Renamable converts it right where it is. Nothing is uploaded.
iPhone photo.heic
PNG.png
holiday.heicholiday.png
Yes
How to do it.
Select holiday.heic in Finder and press Return.
Change .heic to .png and press Return. If Finder asks, choose “Use .png”.
Renamable converts it right there. The original goes to the Trash, or stays next to the new file if you prefer, and you can undo any conversion.
