A complete side-by-side comparison of HEIC and JPG (JPEG) — file size, image quality, browser support, compatibility, and when to use each format.
HEIC (also compared as HEIC vs JPEG) produces smaller files with better quality — typically 40–50% smaller than JPG at equal visual quality. However, HEIC has one critical limitation: it is not supported by any major web browser, Windows without extensions, or non-Apple platforms. JPG works everywhere without exception. For websites in 2026, neither is the best choice — use WebP instead, which beats both in file size and is supported by 97%+ of browsers globally.
| Feature | HEIC | JPG / JPEG |
|---|---|---|
| Compression type | Lossy and lossless modes (HEVC-based) | Lossy only (DCT-based) |
| HEIC vs JPG file size | 40–50% smaller than JPG at equal quality | Larger — baseline format |
| HEIC vs JPG image quality | Better detail at same file size | Good — less compression efficiency |
| Transparency support | Supported | Not supported |
| Multiple images in one file | Yes — Live Photos, burst shots, depth | No — single image only |
| HEIC browser support in Chrome, Firefox, Safari | Not supported in any major browser | Universal — all browsers worldwide |
| Windows support | Requires free Microsoft Store extension | Built-in on all Windows versions |
| Android support | Limited — varies by device and version | Universal across all Android devices |
| Social media upload | Auto-converted to JPG on most platforms | Native support on all platforms |
| Web publishing | Cannot be displayed on websites | Standard web format — works everywhere |
| Re-editing quality | Degrades with each lossy save | Degrades faster with each re-save |
| Developed by | MPEG group — adopted by Apple in iOS 11 (2017) | Joint Photographic Experts Group (1992) |
| Best for | iPhone photo storage, Apple ecosystem archiving | Web, sharing, email, cross-platform compatibility |
HEIC stands for High Efficiency Image Container. It is based on the HEIF (High Efficiency Image Format) standard developed by the MPEG group and adopted by Apple as the default iPhone and iPad camera format starting with iOS 11 in 2017. The "container" design means a single HEIC file can hold multiple images, depth maps, and even short video clips — making it ideal for iPhone features like Live Photos, Portrait Mode depth data, and burst sequences.
HEIC uses HEVC (H.265) intra-frame compression technology, which is far more efficient than the older JPEG algorithm. A HEIC photo from an iPhone typically uses about half the storage of an equivalent JPG while looking equal or better at normal viewing sizes. For someone with thousands of photos, this translates to gigabytes of saved storage. Apple chose HEIC specifically to help users store more photos and videos without running out of space on 64 GB and 128 GB devices.
The main drawback of HEIC is compatibility. Despite being several years old, HEIC is still not supported natively by web browsers, most non-Apple software, or Windows without a separate extension. This means most users need to convert HEIC to JPG before sharing, uploading, or publishing their photos.
JPG — also written JPEG (Joint Photographic Experts Group) — was standardized in 1992 and has been the dominant photo format for over 30 years. It uses Discrete Cosine Transform (DCT) compression to reduce file size by discarding fine image detail that the human eye is less sensitive to. At quality settings of 85%+, the quality loss is invisible to most viewers, making JPG an efficient choice for photographic content across the web.
JPG's greatest strength is its compatibility. Every device, operating system, browser, application, social media platform, and email client on earth supports JPG without any configuration. Digital cameras output JPG. Websites display JPG. Email clients show JPG inline. This 30-year head start means JPG will remain the universal standard format for years to come, even as newer formats like HEIC and WebP offer better compression efficiency.
The main weakness of JPG is generation loss — every time you open and re-save a JPG, another round of lossy compression is applied on top of the previous one. Over multiple edits, this causes visible quality degradation. If you are editing images, always work in a lossless format (PNG or RAW) and only export to JPG as a final step. This is one area where HEIC is superior, as it preserves more detail at smaller file sizes throughout the editing process.
The file size difference between HEIC and JPG is one of the most significant practical factors in choosing between formats. Here is a realistic comparison for typical iPhone photos:
| Image Type | HEIC Size | JPG Size (85%) | HEIC Saving |
|---|---|---|---|
| Standard iPhone photo (12MP) | 2–3 MB | 4–6 MB | ~50% smaller |
| Portrait mode photo | 3–4 MB | 6–8 MB | ~50% smaller |
| Landscape wide angle | 1.5–2.5 MB | 3–5 MB | ~45% smaller |
| Night mode photo | 4–6 MB | 8–12 MB | ~50% smaller |
| 1,000 photos total | ~2.5 GB | ~5 GB | ~2.5 GB saved |
Over a year of iPhone photography, HEIC saves approximately 2–3 GB compared to JPG — a meaningful difference on devices with 64–128 GB of total storage. However, when you need to share or publish those photos, the conversion to JPG (or WebP for web) is unavoidable.
At the same file size, HEIC produces visibly better image quality than JPG. This difference is most noticeable in:
HEIC's superior compression means it avoids the typical JPG compression artifacts: blocky 8×8 pixel patterns, color banding in gradients, and ringing halos around sharp edges. At heavily compressed sizes (below quality 70), JPG artifacts become clearly visible while HEIC maintains much cleaner output.
At high quality settings (JPG 90%+), the difference between HEIC and JPG quality is minimal and difficult to spot without pixel-level comparison. The quality advantage of HEIC becomes most significant when file size is constrained — exactly the scenario on a phone with limited storage.
Despite being introduced in 2017, HEIC compatibility remains inconsistent across non-Apple platforms. This is the single biggest reason users convert HEIC to JPG or JPEG before sharing their photos.

The most common scenario is transferring iPhone photos to a Windows PC or uploading to a website that rejects HEIC. Converting HEIC to JPG (JPEG) solves both problems instantly. Here are all the ways to do it:
For website owners, the answer is unambiguous: do not use HEIC on the web. No browser — Chrome, Firefox, Safari, Edge — supports HEIC as a web image format. If you reference a HEIC file in an HTML image tag, the image simply fails to load entirely for all visitors.
JPG is the safe fallback — universally supported, widely understood by CDNs and CMSes. But for Google Core Web Vitals and PageSpeed Insights performance, JPG is not the best choice either. Google explicitly recommends "next-gen formats" in its Lighthouse audits, specifically referring to WebP and AVIF.
The recommended image stack for websites in 2026:
If your workflow involves shooting on iPhone (HEIC) and publishing to the web, the optimal pipeline is: iPhone HEIC → convert HEIC to WebP → publish on website. This gives you the best possible web performance from iPhone photography.
HEIC is the technically superior format — better compression, better quality, more features. But technical superiority without compatibility is only half the picture. HEIC cannot be viewed in browsers, struggles on Windows without extensions, and is rejected by many upload systems and older apps.
The practical answer to "which is better — HEIC or JPG?" depends entirely on your use case. For storing photos on an iPhone, HEIC is clearly better — you get more photos in less storage space. For sharing, publishing, emailing, or uploading anywhere online, JPG (or WebP for web) remains the correct choice.
The best workflow in 2026: shoot in HEIC on your iPhone to maximize storage efficiency, then convert to JPG when you need to share or publish. IMGVO makes this conversion instant, free, and browser-based — no app download required.
HEIC produces better image quality at smaller file sizes — typically 40–50% smaller than JPG (JPEG) at equal quality. However, JPG has near-universal compatibility across all devices, browsers, and platforms. HEIC is better for storage efficiency on Apple devices; JPG is better for sharing, web publishing, and cross-platform use.
No. HEIC and JPEG (JPG) are completely different formats. HEIC uses modern HEVC-based compression and is mainly used on Apple devices. JPEG uses older DCT compression and is universally supported everywhere. HEIC files use the .heic extension; JPEG files use .jpg or .jpeg. The two formats are not interchangeable without conversion.
Converting HEIC to JPG applies JPG lossy compression, which reduces some quality. At JPG quality 85–90%, the difference is invisible to most viewers. The resulting JPG will be larger than the HEIC but compatible with all devices and platforms. You cannot avoid some quality reduction when converting to JPG, but at high quality settings the difference is imperceptible.
Apple introduced HEIC as the default format for iPhones starting with iOS 11 in 2017. HEIC stores images at half the file size of JPG with equal or better quality, saving storage space on your device. You can change this in Settings → Camera → Formats → Most Compatible to shoot in JPG instead.
Windows 10 and 11 support HEIC but require the free HEIF Image Extensions from the Microsoft Store. Without it, HEIC files appear as blank icons and cannot be opened. Most modern third-party apps like Photoshop and Lightroom support HEIC directly without any extensions needed.
Neither — use WebP for websites in 2026. HEIC is not supported by any major browser and cannot be displayed on websites. JPG works everywhere but WebP is 25–35% smaller than JPG with equal quality. For maximum compression, AVIF beats both WebP and JPG. Use JPG only as a fallback via the HTML picture element.
No — HEIC actually preserves more quality than JPG at the same file size. HEIC uses more advanced compression that reduces artifacts like blurry edges, pixelation, and color banding that appear in heavily compressed JPG files. At equal file sizes, HEIC consistently produces cleaner, more detailed images than JPG.
Partially. Android 12 and newer have improved HEIC support, but it varies significantly by device manufacturer and app. Many older Android devices and apps cannot open HEIC files at all. For reliable cross-platform sharing between iPhone and Android users, convert to JPG before sending.
HEIC is good for storage and archiving on Apple devices. Adobe Photoshop and Lightroom both support HEIC fully, so it fits into professional Apple-centric workflows. However, most professional photography workflows still prefer RAW formats for editing and JPG or TIFF for client delivery, since JPG remains the universal standard across all platforms and clients.
Go to Settings → Camera → Formats and select Most Compatible. This switches the camera to shoot in JPG instead of HEIC. Note that JPG files are larger than HEIC at equivalent quality, so switching will increase storage usage over time — but every photo will be instantly compatible with all devices and platforms without conversion.
