How to Convert HEIC to JPG in Your Browser
HEIC is the format iPhones save photos in by default, using efficient HEVC compression, while JPG remains the format almost every website, app, and older device expects. This guide explains what actually happens during that conversion, and what you gain and lose by making it.

How HEIC becomes JPG
- The browser’s HEIC decoder (heic2any) unpacks the HEVC-coded image data into a full grid of RGB pixel values — the same decode step your Photos app performs to display the picture.
- If the decoded image carries any transparency, it’s flattened onto a solid white background before encoding, since JPEG has no alpha channel to store it in.
- The flattened pixel data is re-encoded by the browser’s JPEG encoder at your chosen quality (default 90%) — a second lossy compression pass on top of whatever HEVC already applied.
- A single-image HEIC downloads as one .jpg file; a multi-image HEIC — a burst or Live Photo — downloads as multiple JPGs or a single ZIP.
What changes when you convert
The main reason people make this conversion is compatibility, not quality. JPEG has near-universal support — Windows, most upload forms, older email clients, and countless apps that HEIC support is still inconsistent on. Converting removes the “unsupported format” problem entirely.
Quality-wise, this is genuinely a second lossy encode: HEVC already compressed the original once, and JPEG compresses it again after decoding to raw pixels. At high quality settings the difference is usually hard to notice, but it isn’t a lossless step — lowering the quality slider compounds with whatever detail HEVC already discarded.
EXIF and camera metadata — capture settings, GPS location, timestamps — are stripped entirely. If the photo looks correctly oriented afterward, that’s because the browser applied the EXIF orientation flag while decoding, not because the orientation metadata itself survived into the JPG.
When JPG is the right choice — and when it isn’t
JPG is the right call whenever the photo needs to go somewhere HEIC might not be recognized — social platforms, older devices, most web forms, or anyone not using an Apple device. It’s the most broadly compatible option among the formats HEIC converts to here.
It’s the wrong choice if you need to preserve transparency (rare for a straight camera photo, but present in some edited HEIC files) or want to avoid a second round of lossy compression — PNG keeps both the pixels and any transparency exactly as decoded, at the cost of a larger file.
Limitations and privacy
Decoding depends on heic2any in the browser — unusual HEIC variants or older browsers can fail even when the file opens fine on an iPhone. Trying another modern browser, or exporting a JPG directly from the Photos app, usually resolves it.
EXIF and other metadata are not preserved in the download, and multi-image HEIC files always produce more than one output. Conversion runs entirely in your browser and works on Windows and Android without any Apple software installed — the photo is never uploaded to Looty Tools servers.
Convert HEIC to JPG FAQ
- Why do iPhone photos need to be converted to JPG in the first place?
- HEIC is efficient but still isn’t recognized everywhere — some websites, older software, and non-Apple devices expect JPG specifically. Converting sidesteps that compatibility gap rather than fixing any flaw in the HEIC file itself.
- Does converting HEIC to JPG discard my photo’s location and camera data?
- Yes. EXIF data such as GPS coordinates, capture settings, and timestamps is not carried into the JPG — there’s no option in this tool to keep it.
- Why does the JPG still look right-side-up if the orientation metadata isn’t kept?
- The browser applies the EXIF orientation flag while decoding the HEIC, rotating the actual pixels before the JPG is encoded. The image looks correct because the pixels themselves are already oriented — not because the orientation tag survived into the output file.
- What happens to transparency in a HEIC file when it’s converted to JPG?
- It’s flattened onto a solid white background, since JPEG has no alpha channel at all. This mainly matters for edited HEIC files with transparent areas — a typical camera photo has none to begin with.
- Is there a way to convert HEIC to JPG without any quality loss?
- Not with this conversion — going from HEVC to JPEG is a genuine second lossy encode. For a lossless result, HEIC to PNG avoids the extra compression pass, at the cost of a much larger file.
