While it's common to convert HEIC to JPG, you may sometimes want to convert JPG/JPEG to HEIC format instead. This guide explains in detail how to convert JPG/JPEG to HEIC. We cover why such conversion is needed, available methods, and important considerations.

Why Convert JPG to HEIC?

The main reason to convert JPG/JPEG to HEIC is to save storage space. HEIC format can maintain equivalent or superior image quality while reducing file size by approximately half.

Especially when using Apple devices like iPhone or iPad, using HEIC format when storing large numbers of photos can significantly save storage capacity.

Additionally, HEIC format supports 16-bit color depth, enabling richer color representation. However, converting from JPG to HEIC won't provide additional information if the original JPG has 8-bit color depth.

Warning:Converting from JPG to HEIC won't restore already lost image quality information. Also, since HEIC format may not be supported on some devices and applications, check compatibility before converting.

Conversion Method on Mac (Recommended)

On Macs running macOS High Sierra or later, you can convert JPG to HEIC using standard features. This is the easiest and most reliable method.

1
Prepare JPG Files
Check the JPG/JPEG files you want to convert in Finder.
2
Batch Convert Using Automator (Method 1)
Using the Automator app, you can batch convert multiple JPG files to HEIC. You can also create 'Quick Actions' to convert directly from Finder.
3
Use Image Capture or Preview (Method 2)
Using Image Capture app, you can import JPG files and export them in HEIC format. Alternatively, using Preview app, you can open JPG and select HEIC format in 'Export' (macOS Mojave or later).
4
Use Command Line (Method 3 - Advanced)
Using Terminal app, you can convert JPG to HEIC using the sips command. Example: `sips -s format heic input.jpg --out output.heic`

Conversion Using Online Tools

Currently, online tools that can convert JPG to HEIC are limited. HEIC.Best primarily supports conversion from HEIC to JPG/PNG/PDF, but reverse conversion (JPG→HEIC) is only available with some tools.

When using online tools, choose trustworthy services and check privacy policies. It's also important to verify that converted HEIC files work correctly.

Generally, if you're using a Mac, we recommend using standard features. Windows users may need dedicated desktop software.

Important Considerations During Conversion

Quality Limitations

Converting from JPG to HEIC won't provide the benefits of HEIC's 16-bit color depth if the original JPG has 8-bit color depth. Also, already lost image quality information cannot be restored.

Compatibility Issues

HEIC format is not supported on all devices and applications. When sharing converted files with others, you need to confirm that their devices support HEIC.

File Size Reduction

Converting to HEIC format can reduce file size by approximately half in some cases. However, if the original JPG is already highly compressed, the reduction may be smaller.

Purpose of Conversion

If the purpose is to save storage space, converting to HEIC is effective. However, if compatibility is a priority, we recommend keeping files in JPG format.

Frequently Asked Questions (FAQ)

Can I convert JPG to HEIC on Windows?

Windows doesn't support converting JPG to HEIC using standard features. You may need dedicated desktop software. Generally, conversion on Mac is the easiest.

Does converting JPG to HEIC improve image quality?

What about compatibility of converted HEIC files?

HEIC files are natively supported on iPhone/iPad running iOS 11 or later, and Macs running macOS High Sierra or later. Support on Windows and Android is limited.

Summary

Converting JPG/JPEG to HEIC can save storage space. On Mac, you can easily convert using standard features, but Windows users may need dedicated software. Before converting, consider compatibility issues and clarify the purpose of conversion. If the purpose is to save storage space, converting to HEIC is effective, but if compatibility is a priority, we recommend keeping files in JPG format.
