macOS understands HEIC. Finder shows thumbnails, Preview opens the still, Photos imports the library. You convert to JPEG on a Mac not because the OS is blind, but because someone else is: a Windows recipient, a website, a printer queue, or a CMS that still lists JPG and PNG only.

Preview export

Preview is the built-in path for one file or a handful:

Open the HEIC (or select several in Finder and open with Preview).
File → Export. In older macOS this may read Export… with a Format menu.
Choose JPEG. Set quality. Save. The new file is a .jpg (or .jpeg depending on the dialog).

Apple’s Preview help lives in the Preview User Guide on support.apple.com. Export is a new file; the HEIC remains. For many files, Preview gets tedious — you click through dialogs per document unless you use a shortcut or a batch tool.

Photos app

If the shots are already in Photos on the Mac: select, File → Export → Export [number] Photos. Pick JPEG, a quality, and a color profile (sRGB is the safe default for the web and Windows). Photos can also export unmodified originals, which will still be HEIC if that is what the camera wrote. Use JPEG export when the destination cannot read HEIC.

Finder Quick Actions

On recent macOS, a Quick Action or Automator/Shortcuts workflow can convert images in place or to a folder. Right-click a HEIC in Finder and look for Convert Image or a custom shortcut you installed. Built-in convert actions, when present, call the same system codecs Preview uses. They run locally. Avoid third-party “dropzone” apps that sync the file to a server unless you read their privacy policy and want that.

Safari and this converter

Safari can decode HEIC natively, so this site’s worker often takes the fast path: createImageBitmap, canvas encode, done. Drop a folder’s worth of files (up to the limits) and download a ZIP. The ZIP uses STORE — it does not recompress the JPEGs. Filenames map IMG_1234.heic → IMG_1234.jpg, which matches what Preview would give you.

Use the browser when you want the same steps you would use on Windows, or when you are already in a browser handing files to a form. Use Preview when you want macOS color management UI in front of you.

Keep HEIC as the original

On a Mac you have no compatibility excuse to throw HEIC away. It is smaller and it is what iPhone edits round-trip through. Export JPEG for the world; keep HEIC for you. Live Photos still export a still from this tool. For the motion, export the paired video from Photos.

sips and Shortcuts

macOS ships sips, a command-line image tool. sips -s format jpeg IMG_1234.heic --out IMG_1234.jpg writes a JPEG using system codecs. A for f in *.heic; do sips -s format jpeg "$f" --out "$f.jpg"; done loop in Terminal will batch a folder. Quality flags exist; they are not the same numbers as this site’s 0.92 slider. Shortcuts on Mac can wrap the same convert-image action you use on iPhone. Use those when you already live in Terminal or Shortcuts. Use this page when you want the same dropzone you would use on Windows, with ZIP and a quality slider that matches the other OS.

Color management: Preview and Photos let you pick a profile. The browser canvas path is sRGB-ish and good enough for email. If a print shop sent an ICC spec, export from Photos, not from a tab. If they only said “JPEG please,” either path is fine. Continuity Camera can dump a HEIC onto the Mac from the iPhone shutter; it is still a HEIC until you export.
