Hello. I sometimes receive images in HEIC format and I use an app to convert them to JPG. However I realized that this app uploads the images and makes the conversion in the cloud, so I stopped using it.

Does anyone know of an app that does this conversion offline?

  • Image Resizer is a great OSS app on F-Droid that supports converting between several image formats, including HEIC. It works locally, and does a bunch of other stuff, like (obv) resizing, stripping EXIF data, cropping, etc. It’s nice looking, relatively small (9MB), and just a nicely done tool.
