How to Batch Convert HEIC/WebP to JPG?

Converting a single image is easy—you can just open it in Paint and "Save As." But what if you have 500 photos from your holiday trip in HEIC format, and you need to send them to a relative who uses Windows 7?

Manually converting them one by one would take hours. Fortunately, there are efficient ways to handle batch conversion.

Method 1: Browser-Based Batch Tools (No Install)

The most convenient method for most users is an online batch converter. However, you must be careful about privacy. Many sites ask you to upload files to their servers.

Why Xoupai is different: Our Batch Image Converter processes files locally using JavaScript. This means you can drop 100 files, and they convert instantly using your computer's power, without uploading anything.

Method 2: macOS Preview (Built-in)

If you are on a Mac, you don't need extra software:

1. Select all the images in Finder.
2. Right-click and Open with Preview.
3. Inside Preview, click Edit > Select All.
4. Click File > Export Selected Images.
5. Choose "JPEG" as the format and click Save.

Method 3: Windows PowerToys

For Windows Power Users, Microsoft offers a free utility suite called PowerToys.

1. Install PowerToys from the Microsoft Store.
2. Enable the "Image Resizer" module.
3. Select your files in File Explorer, right-click, and choose "Resize pictures" (it can also change formats in settings).

Method 4: Command Line (ImageMagick)

For developers and sysadmins, ImageMagick is the industry standard. Once installed, you can use a simple command to convert an entire folder:

magick mogrify -format jpg *.heic

This command finds every HEIC file in the current folder and creates a JPG copy.

Conclusion

For quick, privacy-safe conversion of 10-50 images, use Xoupai. For managing thousands of files locally, install ImageMagick or PowerToys.
