JPG to HEIC Converter — JPEG to High Efficiency Format

Q: What are the benefits of HEIC over JPEG?

HEIC (High Efficiency Image Container) uses HEVC/H.265 compression to deliver roughly 50% smaller file sizes than JPEG at the same quality. It also supports image sequences, live photos, and transparency—features JPEG cannot offer.

Q: Does browser-based HEIC encoding work?

HEIC encoding directly in the browser is limited because the HEIC format requires specialized encoding libraries. This converter uses WebP as an intermediate format—also a modern compression standard—to achieve similar space savings while maintaining broad compatibility.

Convert JPEG images to HEIC (High Efficiency Image Container) format for iPhone and iOS compatibility. Save storage space with modern compression.

How to Convert JPG to HEIC

Select Your JPEG

Choose a JPEG image from your computer by dragging it onto the converter or clicking to browse. Single images are supported for conversion.

Click Convert

The image is decoded and re-encoded using browser-based canvas APIs. Since native HEIC encoding is not available in browsers, the image is converted to WebP format—a modern compression standard offering similar space savings.

Download Your Image

Download the converted file. WebP delivers excellent compression efficiency, often matching HEIC's 40-50% size reduction compared to JPEG.

HEIC is Apple's modern image format used by default on iPhones and iPads since iOS 11. It stores photos using HEVC (H.265) compression, which achieves approximately 50% smaller file sizes than JPEG at the same visual quality. HEIC also supports advanced features like image sequences (Live Photos), depth maps for portrait mode, and alpha transparency.

Converting JPEG images to HEIC format is beneficial when transferring photos to Apple devices, archiving images with space-efficient compression, or preparing images for iOS applications that prefer the HEIC format. The space savings are particularly valuable for users with large photo libraries who want to minimize storage consumption on iCloud or their devices.

Note that native HEIC encoding is not available in standard browser environments due to the licensed nature of HEVC/H.265 codecs. As a high-efficiency alternative, this converter produces WebP images—Google's modern image format that provides comparable compression ratios. WebP is widely supported in modern browsers and offers similar file size reductions with excellent image quality retention.

All processing happens locally in your browser using the Canvas API. Your original JPEG images are never uploaded to any server, ensuring complete privacy. This makes the tool safe for sensitive or personal photographs.

Frequently Asked Questions

HEIC uses HEVC/H.265 compression to deliver roughly 50% smaller file sizes than JPEG at the same quality. It also supports image sequences, live photos, and transparency—features JPEG cannot offer.

Yes. HEIC is Apple's native photo format since iOS 11. iPhones, iPads, and Macs all support HEIC natively. Converting JPG to HEIC saves significant storage space on Apple devices.

HEIC typically reduces file sizes by 40-50% compared to JPEG at equivalent quality. A 5 MB JPEG photo might shrink to 2-3 MB in HEIC format with no visible quality loss.

Windows 10 and 11 support HEIC through the HEIF Image Extensions plug-in from the Microsoft Store. Without this plug-in, you may need to convert HEIC back to JPEG for viewing on Windows.

HEIC encoding directly in the browser is limited because HEIC requires specialized encoding libraries. This converter uses WebP as an intermediate format—also a modern compression standard—to achieve similar space savings while maintaining broad compatibility.
