When one eludes my ban ... (see other posts how to ban it inside the phone, but it exists outside (people send me messages)) [0] samples to play with.

On the desktop, Preview app (and lots of others) will open and export as ...

On the phone (Apple, sometimes you bewilder me), You can convert in Files, not Photos. 1. Save a photo to FILES from camera roll or web (This works with webp, as well) 2. click and hold the THUMBNAIL, do not open the image. 3. Quick Actions -- Convert image. 4. You can now "save" the image (open, do not click and hold) to your camera roll.

This is BONKERS

As others have noted, "There's an app to do it".

Worst for me in daily life, when you get info on an image (in the camera roll, pull up on the image) WEBP does not even show as a file type. HEIC does.

ios 18, not 26.

I use VIPS cli https://www.libvips.org

I think converting HEIC into jpg would be simple

  vips copy -i src.hif out.jpg

Although I have not used it for a while so not sure it is exactly that. It also does not support batches, you must run one image at a time, but that can be scripted. It also does not support multiple operations, so you might need to use the .v extensions as intermediary between multiple presets(for example sepia + resize + crop).

I’ve always right-clicked the image(s) in Finder, selected Quick Actions, and picked Convert Image. Does this still work on newer Macs?

To make it perfectly clear, no browser support outside Appleworld

I use Photoshop. (Where's Cindy when I need her?)

On macOS if you drag a synced HEIC photo from Photos.app to the Finder it automatically gets converted to a JPEG.

On NixOS, the libheif package provides a `heif-dec` command, which you can use as follows:

    heif-dec foo.heic foo.jpg

HEIC is a container; HEIF is a container format. I don't know why images from my iPhone get saved with a HEIC extension... seems like it should be HEIF.

That said, when I move photos from my phone to by desktop via Signal; somewhere along the way it gets converted to JPEG so it's not a concern.

heif-convert CLI https://github.com/NeverMendel/heif-convert

Use it to convert customer images sent from iphones.

there's a settings on ios to use jpgs always and just remove HEIC from your life!

Settings -> Camera -> Formats -> Most Compatible

I use LiveConvert (it runs locally on your phone). https://apps.apple.com/no/app/liveconvert-heic-to-jpg/id6747...

Settings -> Apps -> Photo -> Transfer to Mac or PC (Automatic).
