How to convert HEIC to JPG on a Mac

iPhones shoot HEIC by default. It's an efficient format — until you need to upload to a website, send to a Windows user, or feed an app that only speaks JPEG. Here's how to convert on macOS, one photo or hundreds.

1. Finder's Quick Action (fastest for a few files)

Select HEIC files in Finder, right-click → Quick Actions → Convert Image → choose JPEG. Quick, built in, no options beyond a rough size choice.

2. Preview (one at a time, with quality control)

Open the HEIC in Preview → File → Export… → Format: JPEG, pick a quality. Fine for a single photo; tedious for a camera roll.

3. TinyPresso (batch convert + compress in one step)

If you're converting more than a handful — or you care about the resulting file sizes — TinyPresso does both jobs at once: set Format → JPEG in the sidebar, drop in your HEIC photos (any number, no size limits), and press Compress. Every photo comes out as a compressed JPEG copy; your originals stay untouched.

Because TinyPresso is 100% offline, your photos never touch a server — worth caring about for personal photo libraries. It's free, and it also converts the other direction (JPEG/PNG → HEIC) plus to WebP and AVIF if you're preparing images for the web.

Stop the problem at the source (optional)

If you never want HEIC in the first place: on your iPhone, Settings → Camera → Formats → Most Compatible makes the camera shoot JPEG. The trade-off is larger files on the phone — many people prefer keeping HEIC there and converting on the Mac when needed.
