About JPEG to HEIC Conversion
Encoding to HEIC isn't something a web browser can actually do — HEIC is built on the HEVC video codec, and no browser exposes an HEVC encoder to web pages, only decoders. That's true of every browser-based tool, not just this one: if a site claims to convert JPEG to HEIC entirely client-side, it's either quietly producing something else or lying about what happened. Here's what's actually possible instead.
Why JPEG → HEIC Doesn't Work in a Browser
HEIC (High Efficiency Image Container) stores its image data using HEVC (H.265) compression — the same codec family used for high-efficiency video. Reading HEIC is solvable: Safari decodes it natively, and in other browsers a web page can bring its own decoder, which is what our HEIC converters do. But licensing and complexity mean no browser exposes an HEVC *encoder* to JavaScript. Without that, there's no way to actually produce valid HEIC bytes using only browser APIs.
This is a one-directional limitation: converting HEIC to JPEG works fine (decoding is possible in every modern browser), which is why that's by far the more common conversion. Going the other way — encoding — needs either a native app (iOS/macOS Photos, or dedicated desktop software) or a server running a real HEVC encoder, neither of which fits a private, browser-only tool.
If you've landed here wanting a smaller file than JPEG, AVIF and WebP are both real, working alternatives — modern, well-compressed formats that a browser genuinely can encode.
What to Use Instead
- Want a smaller file than JPEG, encoded right here in the browser? Try JPEG to WebP or JPEG to AVIF — both are real, working conversions.
- Specifically need a HEIC file (e.g., to match an iPhone's format)? That requires an Apple device or dedicated encoding software — no browser-only web tool can produce genuine HEIC.
- Have HEIC photos and want them in a common format instead? That direction *is* fully supported — our HEIC to JPEG converter and HEIC to PNG converter both work entirely in your browser.
Every other tool on this site that touches your files still runs entirely client-side — nothing is uploaded to a server.
Frequently Asked Questions
No — and this is worth being upfront about rather than pretending otherwise. HEIC encoding requires an HEVC video encoder, which no web browser exposes to JavaScript. Any purely browser-based tool claiming to do this is either silently giving you a different format or not actually working.
It's a fundamental platform limitation, not a bug in this tool — browsers simply don't provide the encoder needed. Unlike some other formats, this isn't something that can be added later with a JavaScript library, since HEVC encoding is patent-licensed, computationally heavy technology that isn't available as a lightweight browser-side library.
On an iPhone or Mac, exporting or saving a photo through Apple's own Photos app produces genuine HEIC. On other platforms, you'd need dedicated conversion software with a real HEVC encoder — not something a website can do in your browser tab.
AVIF or WebP — both are modern, well-compressed formats that browsers genuinely can encode client-side. Our JPEG to AVIF and JPEG to WebP converters do this for real, with no upload required.
Yes. Our HEIC to JPEG converter works in Chrome, Edge, Firefox and Safari, entirely on your device: Safari reads HEIC natively, and in other browsers the converter loads its own HEIC decoder. Nothing is uploaded.
