What is the difference between HEIC and JPEG?

HEIC (High Efficiency Image Container) uses HEVC/H.265 encoding to compress images up to 50% smaller than JPEG while maintaining equivalent quality. JPEG uses the older DCT-based compression algorithm from the early 1990s. HEIC supports 16-bit colour depth, transparency, image sequences, and live photos — none of which JPEG supports natively.

Is HEIC better quality than JPEG?

At the same file size, HEIC delivers noticeably better quality than JPEG — fewer artefacts, smoother gradients, and better detail retention. At equivalent visual quality, HEIC files are typically 40-50% smaller. The HEVC compression is simply more efficient, which is why Apple adopted HEIC as the default capture format starting with iOS 11.

Are HEIC files smaller than JPEG?

Yes, significantly. A 12-megapixel iPhone photo saved as HEIC is typically 1.5-2.5 MB, while the same photo as JPEG is 3-5 MB. That is roughly 50% savings. For burst photos and Live Photos, the savings compound because HEIC stores multiple images in a single container file rather than separate JPEG frames.

Which devices and apps support HEIC?

HEIC is natively supported on Apple devices (iPhone, iPad, Mac running iOS 11+ / macOS High Sierra+). On Windows, the HEIF Image Extension from the Microsoft Store enables viewing and editing. Android supports HEIC from Android 10 onward. Most modern photo apps (Photos, Lightroom, Affinity, GIMP) handle HEIC with the right plugins. Older software and many web platforms still require conversion to JPEG.

How do I convert HEIC to JPEG?

You can convert HEIC to JPEG using our free online HEIC converter — it runs entirely in your browser, so your photos never leave your device. For bulk conversion, our bulk image compressor supports batch HEIC-to-JPEG conversion. On iPhone, you can also change the camera format back to "Most Compatible" (JPEG) in Settings > Camera > Formats.

Should I use HEIC or JPEG for my photos?

Use HEIC if you shoot primarily on iPhone, share within the Apple ecosystem, and want to save storage space and iCloud bandwidth. Use JPEG for universal compatibility — when sharing with Android users, uploading to websites, sending via email, or posting to social media platforms that do not support HEIC. Many photographers use HEIC for archival storage and convert to JPEG only when sharing externally.

Comparison Format guide

HEIC vs JPEG compression.

Apple's HEIC format promises half the file size of JPEG with better quality. But compatibility matters. Here is how the two formats compare for storage, quality, and everyday sharing.

Quick comparison

Feature	HEIC	JPEG
Compression type	HEVC/H.265 (high efficiency)	DCT-based lossy
File size saving	40-50% smaller than JPEG	Baseline (reference)
Image quality	Better at equivalent bitrate	Good, more artefacts at low bitrate
Transparency	Alpha channel supported	Not supported
Colour depth (HDR/10-bit)	Up to 16-bit with HDR support	8-bit, no HDR
Animation	Image sequences and Live Photos	Not supported (MJPEG impractical)
Device support	Apple native, Android 10+, Windows (with HEIF extension)	Every device, camera, and platform
Browser support	Safari only (limited)	100% across all browsers
Best for	Apple ecosystem, archival, HDR photos	Universal sharing, web, cross-platform

What is HEIC?

HEIC (High Efficiency Image Container) is Apple's implementation of the HEIF (High Efficiency Image File Format) standard, using HEVC (H.265) video compression internally to encode still images. Apple introduced HEIC as the default camera format with iOS 11 in 2017, replacing JPEG for photos taken on iPhone and iPad. The format delivers roughly 50% file size reduction compared to JPEG at the same visual quality, thanks to the more advanced block-partitioning and motion-compensation techniques inherited from video encoding.

Beyond compression efficiency, HEIC supports features that JPEG simply cannot match: 16-bit colour depth for HDR captures, an alpha channel for transparency, image sequences for Live Photos, multiple images in a single container file, and lossless rotation without re-encoding. These capabilities make HEIC technically superior as a capture format, which is why the MPEG group designed HEIF as the natural successor to the decades-old JPEG standard.

The JPEG standard

JPEG (Joint Photographic Experts Group) has been the universal image format since its standardization in 1992. It uses a lossy compression pipeline — colour space conversion, chroma subsampling, DCT block transform, quantization, and Huffman/arithmetic encoding — that discards visually less important information to achieve compact file sizes. Despite its age, JPEG remains the most widely supported image format on earth. Every browser, camera, phone, printer, and social media platform handles JPEG without any plugins or configuration. Use our JPEG compressor to optimise your JPEG images with the latest encoder improvements.

HEIC vs JPEG: file size comparison

A 12-megapixel photo from an iPhone 15 Pro: HEIC at standard quality: 1.8-2.5 MB. JPEG at equivalent quality: 3.5-5 MB. Saving: 45-50% storage reduction with indistinguishable visual quality in normal viewing conditions.

A 48-megapixel ProRAW photo from an iPhone 15 Pro Max: HEIC (High Efficiency): 3-5 MB (computational compression from the A17 Pro chip). JPEG (from camera output): 8-12 MB. Saving: 55-60% — the gap widens at higher resolutions because HEVC's motion-compensated encoding handles fine detail more efficiently than DCT blocks.

A Live Photo burst (1.5 seconds of frames): HEIC: 2-3 MB (key frame + delta frames stored in a single container). JPEG (separate frames): 8-12 MB for the same sequence. Saving: Up to 75% — HEIC's video-derived encoding handles temporal redundancy natively, whereas JPEG wastes space storing every frame independently.

Compatibility and conversion

The biggest practical disadvantage of HEIC is compatibility. While Apple devices handle HEIC seamlessly — Photos, Finder, Mail, and AirDrop all work with the format — the rest of the world is slower to adopt it. Many web platforms, CMS systems, social media uploaders, and enterprise software still expect JPEG. If you share HEIC files with Android users, they may see a blank placeholder or receive an unopenable attachment. Our HEIC to JPEG converter solves this instantly — upload your HEIC photos and download standard JPEG versions, all processed in your browser with zero uploads to any server. For batch workflows, the bulk image compressor handles thousands of HEIC files at once.

The Verdict

HEIC is objectively the better format for capture and storage within the Apple ecosystem — it saves disk space, preserves more quality, supports modern features like HDR and transparency, and handles Live Photos efficiently. JPEG remains the king of universal compatibility: every device, browser, and platform can open and display it without plugins or conversion. The practical strategy is to shoot in HEIC for everyday use and convert to JPEG — or better yet, WebP — whenever you share outside the Apple ecosystem or upload to the web.
