Why does this only work in some browsers?

HEIC decoding is patent-encumbered and not shipped by most browser vendors. Safari on Apple platforms can decode it; Chrome, Firefox and Edge typically cannot.

What can I do if my browser cannot decode HEIC?

The simplest fix is on the phone: Settings → Camera → Formats → Most Compatible makes the iPhone save JPEG directly. Sharing a photo through most apps also converts it automatically.

Why not just upload it to a server?

Because that would break the promise the rest of this site makes. A tool that says local processing should not silently become a cloud tool when it hits a hard case.

Why is this marked beta?

Because it only works on a subset of browsers. It is excluded from search indexing until it works widely enough to be genuinely useful.

iPhones save photos as HEIC by default. It is an efficient format, and it is also the reason a photo airdropped to a Windows machine or attached to an email so often will not open.

Converting HEIC in a browser is genuinely hard: unlike JPEG, PNG and WebP, HEIC decoding is not built into most browsers. Safari on Apple platforms can do it; Chrome, Firefox and Edge generally cannot. Rather than shipping a large WebAssembly decoder or quietly uploading your photo to a server, KaiConvert checks whether your browser can decode HEIC and tells you the answer.

O que você ganha

Local when your browser allows it
On a browser with native HEIC support the conversion runs on your device like every other tool here.
No silent uploads
If local decoding is impossible, nothing is sent anywhere. You are told the tool cannot run, not handed a fake result.
Standard JPEG output
The converted file opens on Windows, Android, in email clients and in every photo application.
Quality control
The JPEG quality slider is yours, not a fixed default.

Como funciona

1
Capability check
KaiConvert asks the browser whether it can decode image/heic before anything else happens.
2
Decode and re-encode
If supported, the photo is decoded to pixels and written out as JPEG at your chosen quality.
3
Download
A standard .jpg file, ready to share anywhere.

Especificações

This tool is beta. It depends on a native browser HEIC decoder, which most browsers do not ship. KaiConvert detects support up front and refuses to run rather than uploading your photo or fabricating a result.
