How to Batch Convert HEIC Photos

Why batch convert HEIC photos?

If you use an iPhone, your photo library is full of HEIC files. They work perfectly on Apple devices, but the moment you need to share photos with someone on Windows, upload them to a website, or attach them to an email, compatibility breaks down.

Converting one photo is easy. Converting fifty vacation photos one at a time is tedious. Batch conversion lets you process an entire folder of HEIC images in a single step — upload, convert, download as a ZIP. No repetitive clicking, no software to install, no waiting for each file individually.

When batch conversion saves the most time

• After a trip — Convert a hundred iPhone photos before sharing with family on mixed devices.
• Before uploading to a website — CMS platforms, job applications, and online forms expect JPG.
• Migrating to Windows — Moving from Mac or iPhone to a PC? Convert your entire HEIC library first.
• Preparing email attachments — Compress and convert a batch before sending a photo album.
• Print orders — Photo labs and online print services require JPG format.

How to batch convert HEIC to JPG

The process takes under a minute for a typical batch:

1. Open the HEIC converter
2. Select multiple HEIC files — drag and drop a folder or use the file picker to select up to 30 images
3. Wait for conversion — all files process in parallel
4. Download results — save individual JPGs or grab the ZIP archive

You can also use the dedicated HEIC to JPG converter — both tools support batch upload with the same 30-file limit.

Batch conversion on different devices

On Mac

Drag a folder of HEIC files from Finder directly into the converter. macOS handles multi-file selection natively. Download the ZIP and extract in Finder.

On Windows

Select multiple HEIC files using Ctrl+Click in File Explorer. Without the HEIF codec installed, Windows may not show thumbnails, but the converter reads the files correctly regardless.

On iPhone

Open the converter in Safari, tap upload, and select multiple photos from your camera roll. iOS supports multi-select in the photo picker. Download the ZIP to Files and share from there.

Tips for efficient batch workflows

• Organize before uploading — Group photos by event or date. Convert one album at a time for cleaner downloads.
• Keep originals — HEIC files are smaller and higher quality. Convert copies for sharing; do not delete your iPhone originals.
• Check the output — Spot-check a few converted JPGs before deleting HEIC source files from your computer.
• Combine with compression — After batch conversion, run JPGs through a compressor if you need smaller files for email.
• Prevent future conversions — On iPhone, set Settings → Camera → Formats → Most Compatible to shoot JPG going forward.

Batch conversion vs alternatives

For most users with up to 30 photos per batch, the online converter is the fastest and simplest option. For larger libraries, run multiple sessions or use the 30-file batches as manageable chunks.
