How macOS handles HEIC — and where it gets fiddly
Macs are far friendlier to HEIC than Windows. Because macOS shares Apple's imaging frameworks with the iPhone, a .heic file opens straight away in Preview, shows a thumbnail in Finder, and imports cleanly into Photos — no extensions, no purchases. The snag isn't viewing the files, it's handing them to someone else. The moment you need to email a photo to a Windows colleague, upload it to a web form that rejects HEIC, or drop it into an app that only understands JPG, that Apple-friendly format becomes a roadblock. macOS will happily convert, but its built-in routes are designed around one or two images at a time, which turns a whole camera roll into a repetitive chore. That's the gap this browser tool fills: it batches the entire conversion in a single pass while keeping everything on your Mac.
Convert HEIC to JPG on Mac — step by step
Using the tool above is the fastest path when you have more than a couple of files. Nothing installs and your photos never leave the machine.
- Open this page in Safari or Chrome on your Mac.
- In Finder, select your .heic photos (Cmd-click for several, or Cmd-A to grab a whole folder) and drag them onto the drop area above.
- Choose a quality — 85 to 95% is indistinguishable from the original for everyday photos — and let the batch run.
- Click Download all to save every JPG as a ZIP into your Downloads folder. The original HEIC files stay exactly where they were.
The built-in Mac options, and their limits
macOS gives you a few native ways to make JPGs, each fine for small jobs:
- Preview → Export. Open a HEIC in Preview, choose File → Export, pick JPEG and a quality, and save. You can select several files and use Export Selected Images…, but you still step through a dialog each time.
- Photos app → Export. Inside Photos, select images and choose File → Export → Export Photos, then set the format to JPEG. It works well but only for pictures you've imported into the Photos library.
- The "Keep Originals" question. Under Settings → Photos, "Download and Keep Originals" stores the true HEIC, while "Automatically" may hand you a JPG copy on export. And on the iPhone itself, Camera → Formats → Most Compatible shoots new photos as JPG — though that won't touch the HEIC images already on your Mac.
These are great for the occasional file. When you're converting dozens or hundreds, the browser tool is simply quicker and doesn't tie the result to your Photos library. Prefer lossless output for editing? Use HEIC to PNG.
Tips for converting a big batch on a Mac
For a large import, drag the whole folder from Finder in one motion rather than selecting files individually — the queue handles them together. If you're on a MacBook with limited memory, converting in groups of a hundred or so keeps things snappy and avoids straining the browser. Leave the tab in the foreground while it processes, and once the ZIP arrives you can unzip it directly into the destination folder. Because the conversion never edits your source files, you can keep the HEIC originals in Photos as your archive and use the JPGs purely for sharing and uploads.
Frequently asked questions
Can a Mac convert HEIC to JPG without this tool?
Yes. Preview's Export and the Photos app both create JPGs, but they're built for a few images at a time. This tool converts a whole batch in one step with nothing to install.
Does it work in Safari?
Yes. It runs in Safari, Chrome and other modern browsers on macOS, all locally on your machine.
What's the difference between "Keep Originals" and "Automatic"?
"Keep Originals" stores the true HEIC file, while "Automatic" can deliver a converted JPG copy when you export or share. If you have HEIC originals to convert, this tool handles them regardless of that setting.
Will my original photos be changed?
No. The converter reads your HEIC files and writes new JPGs; the originals in Finder or Photos are left untouched.
Are my photos uploaded?
No. Everything runs locally in your browser, so your photos never leave your Mac.
