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

Settings -> Camera -> Formats -> Most Compatible

To make it perfectly clear, no browser support outside Appleworld

I mostly am a DSLR photographer but for the occasional iPhone shot

https://mastodon.social/@UP8/115740936297822037

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

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).

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.

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.

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

Use it to convert customer images sent from iphones.

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).

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

    heif-dec foo.heic foo.jpg

  > cat ~/.local/share/kio/servicemenus/convertHEIF.desktop 
  [Desktop Entry]
  Type=Service
  MimeType=image/heif;
  Actions=convertHEIF

  [Desktop Action convertHEIF]
  Name=Convert to JPEG
  Icon=image-bmp
  Exec=/bin/sh -c "heif-dec -q 95 %u $(dirname %u)/$(basename %u .heic).jpg"

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

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

Hi.

ffmpeg -i input.heic output.jpg

This works on all platforms. You can automate it too. I did for a cloud platform.

Best of luck.

Usually a quick Apple Shortcut is how I go about it

I save my iPhone photos to my linux desktop. The default image viewing software in the Gnome 3 window manager can display HEIC images.

Conversions on the command line are simple enough with imagemagick. Prior to conversion, I use exiftool to rename the files from IMG_0123.HEIC to the date the image or video was taken, followed by a truncated sha256 digest of the file, e.g. 2025-12-22-1732-f8b7302.HEIC. Otherwise, you can get a nasty condition where the IMG_XXXX filenames collide when consolidated into the same directory.

Pillow (python lib) has a plugin

libheic on some old debian had troubles parsing recent metadata, PILLOW did not

You can choose on the share sheet, right?

I’m referring to this:

- select something in Photos, then Share.

- tap “Options” under “1 photo selected” top of sheet.

The first choice there is:

Format:

[√] Automatic

[] Current

[] Most Compatible

Choose Automatic for the best format for the destination or Current to prevent file format conversions. Photos and videos may convert to JPEG, PNG, and H.264 formats if you choose Most Compatible.

Most Compatible will put a jpeg on Drive for example, I just verified myself.

The greybeards would do it with imagemagick, vips, or even ffmpeg. Gives you full control over the quality and you can script it, parallelize it, and more.

On macOS, select images, right click, “Quick Actions,” “Convert Image.”

image magick's convert would work.

Apple generally does this transparently and automatically when exporting photos. If you’re not getting that behavior then you could have it off in settings, it could be your workflow, or it could be a Google Drive bug/limitation. What exactly do you mean by “transfer a photo on my iphone via google drive”? Something like open the Apple Photos app, hit share, select Google Drive, save it somewhere there, go to the Google Drive app, and copy a link?

Are the HEIC photos personal ones being created by an iPhone? There's a setting you can flip that'll make your iPhone just take JPGs. Which could make sense from you if you're not getting any benefit from HEIC. https://support.apple.com/en-us/116944#:~:text=How%20to%20ca...

Also I've had no problem with HEIC photos on GPhotos, Dropbox, etc. But YMMV

on Mac I literally just right click > Quick Actions > Convert Image > convert to jpg

Ruby script on my PATH to use sips to convert to jpeg. I can cd to the directory and run "convert.rb" - will find all HEIC files and convert

    #!/usr/bin/env ruby
    
    def run(extension)
      files = `find . -type f -name "\*.#    {extension}"`.split("\n")
      files.each do |f|
        jpg = f.sub(/\.#{extension}/i, '.jpg')
        if !File.exist?(jpg)
          cmd = "sips -s format jpeg '#{f}' --out '#{jpg}'"
          `#{cmd}`
          puts cmd
        end
      end
    end

    run("HEIC")
    run("heic")

  magick mogrify -format JPG *.heic *.HEIC
