HEIC to JPG Converter: Free & Easy Ways to Convert HEIC Files

If you’ve ever tried to open a photo from your iPhone on a Windows PC and got a blank thumbnail, you’ve met HEIC. Apple’s default image format since iOS 11 saves space beautifully, but it doesn’t always play nice with other devices.

HEIC file size reduction vs JPG: Up to 50% smaller at same quality ·
Windows native support for HEIC: Requires HEIF Image Extension (free) or third-party tools ·
Apple default format: HEIC default since iOS 11 (2017) ·
JPG compatibility: Supported by virtually all devices and software

Five key specs define the HEIC format and its conversion prerequisites.

How do I turn an HEIC file to a JPEG?

Step-by-step conversion using online tools

• Online converters require no installation (BulkPicTools)
• Most allow drag-and-drop upload and batch processing (BulkPicTools)

To convert a single HEIC file online, open a free converter like BulkPicTools, drag your .heic file into the upload area, and download the resulting JPG. The process works on any operating system with a browser. For a batch of files, select all HEIC images in a folder and drag them together — the tool processes them all at once.

Step-by-step conversion using desktop software

• Desktop converters offer offline conversion (Microsoft Tech Community)
• IrfanView with plugins, XnView MP, and NConvert are free options (Microsoft Tech Community)

For users who convert frequently, desktop software eliminates the need to upload files. Install IrfanView and its HEIC plugin pack, then open the HEIC file and save as JPG. XnView MP supports batch conversion with output quality presets. NConvert works from the command line for automated workflows.

The implication: Choose online tools for occasional use, desktop software for recurring conversions.

Why do my photos become HEIC instead of JPG?

Apple’s default format since iOS 11

• HEIC uses HEVC compression (Microsoft Q&A)
• Apple adopted HEIC to save space (Apple Community)

Since iOS 11, Apple’s Camera app saves photos in HEIC by default because the HEVC (H.265) compression provides about 50% smaller file sizes than JPG at the same quality. This helps users store more photos on their iPhones without running out of storage. The format is part of the High Efficiency Image Container (HEIF) standard.

Benefits of HEIC for storage

• HEIC can achieve same quality at half the size (Windows Central)

The trade-off is compatibility. While HEIC saves space on your iPhone, Windows and Android devices often can’t open the files without additional software or conversion. That’s why many users eventually need a converter.

The catch: Space savings on iPhone come at the cost of universal compatibility.

Is HEIC better quality than JPG?

Image quality comparison at same file size

• HEIC can achieve same quality at half the size (BulkPicTools)
• JPG has wider support (Windows Central)

At the same file size, HEIC generally delivers better image quality than JPG because HEVC is a more efficient compression algorithm. However, the difference is most noticeable in areas with high detail or gradients. For everyday photos, most viewers won’t see a difference. The real advantage of HEIC is storage efficiency — not a dramatic quality leap.

Compatibility trade-offs

• JPG is universally supported (Windows Central)
• HEIC support is growing but not universal (Microsoft Apps)

The choice between HEIC and JPG often comes down to context. If you’re keeping photos on your iPhone, HEIC is fine. But if you need to share images with others, email them, or upload to a website, JPG is safer. The conversion step is a small price for universal compatibility.

Two formats, one pattern: HEIC wins on efficiency, JPG wins on reach.

The implication: If you share photos widely, convert to JPG. If you keep them in Apple’s ecosystem, HEIC saves space without visible loss.

How do I convert all my HEIC photos to JPG?

Batch conversion online

• Many online converters support batch uploads (BulkPicTools)
• FreeConvert and iLoveIMG allow multiple files (BulkPicTools)

For converting a whole folder of HEIC images, online batch tools work well. BulkPicTools lets you select all files and drag them into the browser. The converted JPGs are downloaded as a ZIP archive. Most services have a limit of 20–50 files per session, but that’s enough for most users.

Batch conversion with free software

• IrfanView, XnView MP, and NConvert are free batch converters (Microsoft Tech Community)
• Desktop software handles hundreds of files without upload limits

For large batches (hundreds or thousands of images), desktop software is more reliable. XnView MP’s batch conversion wizard lets you set output format, quality, and resize options. IrfanView’s batch mode processes entire folders. NConvert is scriptable for automated workflows.

The pattern: Online batch tools handle dozens of files; desktop software manages thousands.

How do I convert HEIC files to JPEGs in Windows?

Using Windows Photos app with HEIF extension

• Windows HEIF Image Extension required (Microsoft Apps)
• HEVC Video Extensions may also be needed (Microsoft Apps)

Windows 10 and 11 can open HEIC files if you install the free HEIF Image Extension from the Microsoft Store. In some cases, the HEVC Video Extensions (which may cost $0.99) are also required. Once installed, the Photos app can view and print HEIC images, but it does not natively convert to JPG. For conversion, you still need a third-party tool.

“HEIC files require the HEVC Video Extensions package to be installed for the HEIF Image Extension to read or write .heic files.”

— Microsoft Apps (HEIF Image Extension page)

Using third-party converters

• Third-party software like CopyTrans HEIC (Microsoft Tech Community)
• Free desktop tools: IrfanView, XnView MP, NConvert

After installing the codecs, you can use dedicated converters. CopyTrans HEIC is a free tool that adds a right-click “Convert to JPG” option in File Explorer. IrfanView with plugins opens HEIC and saves as JPG. XnView MP handles batch conversion with a few clicks.

“Windows 10 does not natively support HEIC files without codec support, but the codecs are free in Microsoft Store.”

— Microsoft Q&A (Microsoft Q&A community)

What this means: Windows users need two extensions plus a converter to handle HEIC-to-JPG conversion.
