Convert HEIC to JPG Online — Free
Convert iPhone HEIC photos to JPG online — no app install required. Runs in a Web Worker so your photos never leave your device.
How to convert HEIC to JPG
- 1
Add your HEIC file
Drop or select a .heic file. Files up to 50MB process locally in your browser — nothing uploaded.
- 2
Run the conversion
Your HEIC is decoded by a WebAssembly HEIC decoder (libheif-wasm) running inside a Web Worker on your device, then re-encoded as JPG at your chosen quality. The decoder downloads once (~1.5MB), is cached, and nothing uploads to our servers.
- 3
Download your JPG
One click saves the result as a .jpg file. Your original file stays on your device.
Why convert HEIC to JPG?
HEIC is Apple's default iPhone photo format since iOS 11 (2017). It's not supported natively by Windows, most Android apps, older Mac apps, or many websites. Converting to JPG ensures the photo opens on any device, email client, or web platform — essential when sharing iPhone photos with non-Apple users.
Common HEIC to JPG use cases
- Sharing iPhone photos with a Windows user whose Photos app shows HEICs as broken thumbnails without the HEIF Image Extension
- Emailing photos to a recipient whose email client doesn't render HEIC inline (Gmail, older Outlook)
- Uploading iPhone photos to websites that reject HEIC (most older e-commerce, forum, and portfolio platforms)
- Sending photos to an Android user whose messaging app converts HEIC to a tiny preview instead of the full image
What file size to expect
A 12-megapixel iPhone HEIC (default quality) is typically 1.5-2.5 MB. The JPG output at quality 92 is usually 3-5 MB — roughly 2× larger. This is the tradeoff for universal compatibility: iPhones save HEICs very efficiently, and JPG encoding can't match HEIC's 50%+ storage savings at matched visual quality.
Technical notes: HEIC → JPG
HEIC uses the HEVC (H.265) video codec applied to still images in an HEIF container. It supports 10-bit color depth, wide color gamut, and efficient compression — iPhones save HEICs at roughly half the size of equivalent JPGs at matched quality. The WebAssembly decoder supports standard HEIC profiles including multi-image containers (Live Photos use these, but we extract only the still frame). Apple-specific metadata (depth maps from Portrait mode, Live Photo movies, spatial audio) is dropped during conversion since JPG can't carry it.
Compatibility and browser support
Browser HEIC support is rare — only Safari 17+ (macOS Sonoma) decodes HEIC natively. Chrome, Firefox, and Edge don't, which is why this tool uses a WebAssembly fallback decoder that works in any modern browser. First conversion downloads the ~1.5MB decoder; subsequent conversions are instant.
HEIC vs JPG
| HEIC | JPG | |
|---|---|---|
| File size | Very small (efficient codec) | Smaller (lossy) |
| Quality | Lossy | Lossy (adjustable) |
| Transparency | No | No |
| Browser / app support | Apple ecosystem, limited elsewhere | Universal |
| Best for | iPhone photo storage | Photographs, web images, sharing |

Frequently Asked Questions
Why does the first conversion take longer?
The ~1.5MB WebAssembly HEIC decoder downloads on first use, then is cached by the browser. Subsequent conversions are near-instant.
Is HEIF supported too?
Yes — .heic and .heif extensions both use the HEIF container format with HEVC encoding. Both work identically.
Will the JPG be larger than the HEIC?
Yes, typically 1.5-2×. HEIC's HEVC-based codec is significantly more efficient than JPG's DCT.
What about Live Photos and Portrait depth?
Live Photo videos and Portrait mode depth maps are dropped — only the still HEIC frame converts. The movie component is a separate .MOV file stored alongside the HEIC on iPhone.
Does iPhone itself let me export JPG instead?
Yes — Settings → Camera → Formats → Most Compatible. This sets future photos to JPG at capture. Existing HEICs still need conversion (this tool, or AirDrop to a Mac which exports as JPG by default).
Will EXIF and GPS survive?
No — Canvas-based conversion drops EXIF. If you need GPS and timestamps preserved, use a desktop tool like ImageMagick with metadata flags or Apple's native Photos app export.
