How to Batch Convert HEIC Files at Once

Converting HEIC photos one at a time is fine for a single image — but when you’ve got a vacation’s worth of photos, or an entire shared album from a family member, doing them individually is misery. The fix is batch conversion: drop in all your HEIC files at once, convert them in a single pass, and download the whole set together. Here’s how to do it quickly and privately.

The fastest way: a browser-based batch converter

The simplest method needs no software and works identically on every device. Our HEIC to JPG converter is built to handle batches:

1. Open the converter in your browser.
2. Add all your HEIC files at once. Drag a whole selection in, or use the file picker and select multiple files (Ctrl+A on Windows, Cmd+A on Mac to grab everything in a folder).
3. Let it convert. Every file is processed on your device — nothing is uploaded to a server.
4. Download as a ZIP. Instead of saving each photo one by one, grab the entire batch in a single ZIP file.

That’s the whole process. Because the work happens locally in your browser, it’s both fast and private — your photos never leave your machine.

Why this beats the alternatives

You could batch-convert with Preview on a Mac or by installing software on Windows, but a browser converter has real advantages for big batches:

• No install, no account. Nothing to download or sign up for.
• Same steps on every device. Windows, Mac, Chromebook, iPhone, Android — identical process.
• Privacy by default. Local conversion means sensitive photos aren’t uploaded anywhere. Compare that to the risks we cover in why you shouldn’t upload your photos to online converters.
• ZIP download. One file to manage instead of hundreds.

If you’re specifically on a Mac and prefer the built-in route, our convert HEIC to JPG on Mac guide covers Preview’s batch export too.

Handling really large batches

Browser conversion uses your device’s memory, so there’s no artificial file-count limit — but a giant batch on an older or low-memory device can get sluggish. A few tips:

• Split very large jobs into groups (say, 100–200 photos at a time) to keep things smooth.
• Close other heavy tabs before converting a big set, so the browser has more memory to work with.
• Use a computer for huge batches if you can — more memory than a phone means more headroom.

Choosing the output format

Batch conversion works the same whether you want JPG or PNG:

• JPG — smaller files, universal compatibility. Best for sharing, uploading, and freeing up space. Use the HEIC to JPG converter.
• PNG — lossless, preserves every pixel and any transparency. Best for editing or archiving. Use the HEIC to PNG converter.

For most batch jobs — sharing a trip’s photos, sending an album to a Windows user — JPG is the right call.

A common use case: sharing with non-Apple users

The number one reason people batch-convert is to share a pile of iPhone photos with someone on Windows or Android, who can’t open HEIC. Convert the whole album to JPG at once, download the ZIP, and send that — every recipient can open it. We walk through the full scenario in how to share iPhone photos with Windows users.

The bottom line

Don’t convert HEIC files one at a time. Drop your entire set into a browser-based HEIC to JPG converter, let it process everything on your device, and download the whole batch as a ZIP. It’s faster, it’s private, and it works the same on any device — turning a tedious one-by-one chore into a single click.
