HEIC to JPG Converter — Free, In-Browser (No Upload)

Why Your iPhone Photos Need Conversion

Apple chose HEIC as the default iPhone camera format because it stores similar image quality in roughly half the file size of JPEG. The tradeoff is steep: HEIC is patent-encumbered and browsers ship no decoder for it. Drop a .heic file into any web page and the browser simply will not display it as an image.

For most users, that invisible format becomes visible when:

• Windows Photos may refuse to open .heic files until you install a codec extension from the Microsoft Store
• Websites reject HEIC uploads (many do, because they expect only JPEG/PNG)
• Email recipients on Android or Windows see a broken attachment instead of a photo
• You try to edit the file in software that predates HEIC support

JPG is the lingua franca of digital images. Converting HEIC to JPG solves all of these problems instantly.

How This Tool Decodes HEIC in Your Browser

Unlike simpler image converters, this tool cannot rely on your browser's built-in decoders—because browsers have none for HEIC. Instead, it uses heic2any, which is libheif (the open-source HEIC decoder) compiled to WebAssembly. The decoder is approximately 1.4 MB and loads only once, on the first file you convert, so it never wastes bandwidth on pages you don't use.

Everything stays on your device. No file uploads, no server processing, no copy of your photo sent anywhere—the decoder runs in your browser and that's it.

Quality, File Size, and What Gets Lost

JPEG quality is adjustable from 40 to 100% (default 92%). Lower quality compresses the file further but drops image detail; higher quality preserves detail but grows the file. Expect JPG output to be roughly double the size of the original HEIC for the same picture—that is the cost of universal compatibility, because HEIC's compression is more efficient.

One important caveat: this tool does not preserve EXIF rotation data embedded in the photo. If your iPhone photo contains rotation metadata, the decoded image may appear sideways or upside-down in the output. Photos taken in portrait or upside-down are the usual ones affected, so if a converted image comes out sideways, rotate the JPG after downloading it. If you would rather have a lossless copy and do not mind a much larger file, HEIC to PNG is the alternative — PNG discards nothing, but a photograph stored that way is bigger than either the HEIC or the JPG.

When Conversion Fails or Produces Unexpected Results

If the tool reports it couldn't convert the file, confirm it is a valid HEIC or HEIF file (Apple's older variant). Corrupted or incomplete downloads will be rejected. Multi-image HEIC files—such as iPhone Live Photos or burst shots—are handled by extracting the first image only; the rest are discarded. If you need all frames, you will need software designed for batch HEIF sequences, not single-image conversion.
