How to Convert HEIC to JPG on Windows, Mac & Online

What is HEIC and Why Does It Exist?

HEIC stands for High Efficiency Image Container, a file format Apple adopted starting with iOS 11 in 2017. It uses the HEIF (High Efficiency Image Format) standard backed by the MPEG group, and it relies on HEVC (H.265) compression under the hood.

The reason Apple switched to HEIC is straightforward: file size. A typical HEIC photo is 40-50% smaller than an equivalent JPG at the same visual quality. When you take thousands of photos on your iPhone, that savings adds up fast — both on your device storage and in iCloud backups.

HEIC also supports features JPG cannot match: 16-bit color depth, transparency (alpha channels), image sequences (Live Photos), and the ability to store multiple images in a single file. Despite these advantages, HEIC has one major drawback — compatibility.

Why You Need to Convert HEIC to JPG

JPG has been the universal image standard for over 30 years. Almost every website, application, operating system, and printer supports it natively. HEIC, by comparison, is still poorly supported outside the Apple ecosystem.

Here are the most common situations where you need to convert:

• Uploading to websites: Many CMS platforms, e-commerce sites, and social media upload forms reject HEIC files outright.
• Sharing with non-Apple users: Android phones and older Windows machines cannot open HEIC without additional software.
• Printing services: Online print shops typically accept JPG, PNG, or TIFF — not HEIC.
• Email attachments: Some email clients display HEIC files as generic attachments rather than inline images.
• Editing in older software: Photoshop versions before CC 2020 and many free editors lack HEIC support.

How to Convert HEIC to JPG on Windows

Windows 10 and 11 can display HEIC files if you install the HEIF Image Extensions and HEVC Video Extensions from the Microsoft Store. However, viewing is not the same as converting. Here are your options:

Method 1: Use an Online Converter (Fastest)

The quickest approach is to use our HEIC to JPG Converter. Simply drag and drop your files, and the conversion happens instantly in your browser — no software to install, no files uploaded to any server.

1. Open the HEIC to JPG tool.
2. Drag your HEIC file(s) onto the upload area, or click to browse.
3. The conversion starts automatically.
4. Download your JPG file(s).

Method 2: Windows Photos App

If you have the HEIF extensions installed, open the HEIC file in Photos, click Edit & Create > Edit, then use Save a copy and choose JPG as the output format. This works but is tedious for more than a handful of images.

Method 3: Paint (Windows 11)

Windows 11's updated Paint app can open HEIC files directly. Open the file, then go to File > Save as > JPEG picture. Again, this is a one-at-a-time approach.

How to Convert HEIC to JPG on Mac

macOS has native HEIC support, so conversion is built right in:

Method 1: Preview (Built-in)

1. Open the HEIC file in Preview.
2. Go to File > Export.
3. Select JPEG from the Format dropdown.
4. Adjust the quality slider if needed (80-90% is usually the sweet spot).
5. Click Save.

Method 2: Automator Batch Conversion

For bulk conversion, create an Automator Quick Action:

1. Open Automator and choose Quick Action.
2. Add the Change Type of Images action and select JPEG.
3. Save the workflow. Now you can right-click any selection of HEIC files in Finder and convert them all at once.

Method 3: iPhone Settings (Prevent the Problem)

You can tell your iPhone to shoot in JPG from the start: go to Settings > Camera > Formats and select Most Compatible instead of High Efficiency. The trade-off is larger file sizes on your phone.

Batch Converting Multiple HEIC Files

When you have dozens or hundreds of HEIC photos — say, from a vacation — converting them one by one is impractical. Our HEIC to JPG Converter supports batch conversion: select multiple files at once and download them all as converted JPGs.

For command-line users, ImageMagick handles bulk conversion efficiently:

magick mogrify -format jpg *.heic

This converts every HEIC file in the current directory to JPG. You can also use sips on macOS:

for f in *.heic; do sips -s format jpeg "$f" --out "${f%.heic}.jpg"; done

Quality and File Size Considerations

Converting from HEIC to JPG involves re-encoding, which means a small quality loss is inevitable since both are lossy formats. Here are practical tips to minimize degradation:

• Use 90-95% JPG quality for photos you plan to print or edit further. The file will be larger, but you preserve detail.
• Use 80-85% quality for web use or sharing. The visual difference from 95% is nearly imperceptible, but the file size drops significantly.
• Never convert back and forth. Each re-encoding cycle introduces more artifacts. Convert once and keep the result.
• Preserve the original HEIC. Keep your HEIC files as an archive, especially for important photos. They are your highest-quality source.

A typical 12-megapixel iPhone photo is about 1.5-2.5 MB in HEIC format. The same photo as a JPG at 90% quality will be roughly 3-5 MB. If you are converting photos for a website, consider also running them through our Image Compressor afterward to further reduce file size without visible quality loss.

HEIC vs JPG vs WebP vs PNG: Which Should You Use?

If compatibility were not an issue, HEIC would be superior to JPG in almost every measurable way. But compatibility matters. Here is how the formats compare for common use cases:

• For sharing photos: JPG remains the safest choice. Everyone can open it.
• For web publishing: WebP offers better compression than JPG with broad browser support. Consider our Image Format Converter to switch between formats.
• For archival: Keep the original HEIC or convert to PNG/TIFF for lossless preservation.
• For transparency: PNG or WebP. JPG and HEIC (in its common form) do not support transparent backgrounds.

The bottom line: HEIC is excellent for storage efficiency on Apple devices, but JPG is still the lingua franca of digital images. When you need maximum compatibility, convert to JPG and move on.
