About heic to jpg
HEIC is what an iPhone saves by default and it is a genuinely better format than JPEG — roughly half the file size at the same visual quality, with support for wider colour and higher bit depth. The problem is not the format. The problem is that Apple adopted it years before the rest of the computing world did, so a photograph that looks fine on your phone becomes an unopenable file the moment it lands anywhere else.
The symptoms are familiar. Windows says it cannot open the file, or shows a Microsoft Store prompt for a codec. An upload form rejects the file type. A colleague replies asking what a .HEIC is. Older Android builds show a grey box. Converting to JPEG solves all of it at once, because JPEG is the one image format that every piece of software written in the last thirty years can read.
Decoding HEIC needs a real decoder, which browsers on Windows and Android do not have. This tool bundles libheif compiled to WebAssembly and runs it in the tab. That is why the first photo takes a moment longer than the rest — the decoder loads once and then stays warm for the session. It is also why this works regardless of what operating system you are on.
That decoding requirement is exactly why so many people end up uploading HEIC files to a conversion site, and exactly why doing it locally matters. The photographs people most often need converted are not holiday snaps. They are photographs of documents: an ID card, a signed form, a medical letter, proof of address for an application. Handing those to an anonymous web service to work around a codec gap is a poor trade, and it is avoidable.
Where HEIC works and where it does not
| Platform | Opens HEIC | What happens |
|---|---|---|
| iPhone, iPad, macOS | Yes | Native support throughout |
| Windows 11 | Sometimes | Prompts for a paid codec from the Store |
| Windows 10 | Rarely | Usually refuses to open the file |
| Android | Varies | Newer versions handle it, older show nothing |
| Web upload forms | No | Commonly rejected as an unsupported type |
| Email clients | Varies | Often an attachment nothing will preview |
HEIC to JPG FAQ
Why will Windows not open my iPhone photos?
They are HEIC, and Windows does not include a decoder by default — it offers a paid codec from the Microsoft Store instead. Converting to JPG avoids the problem entirely.
Does this work without installing anything?
Yes. A WebAssembly build of libheif is bundled with the page and runs in the tab, so it does not depend on your operating system having HEIC support.
Why is the first photo slower than the rest?
The decoder loads once, on the first file. Everything after it in the same session converts much faster.
Will I lose quality converting HEIC to JPG?
A little, since the image is decoded and re-encoded once. At the default quality it is not visible at normal viewing sizes. Raise the quality slider if you are archiving.
Can I convert a whole folder at once?
Yes. Add as many files as you like and download the batch as a single zip.
Are my photos uploaded to be converted?
No, and that is the point of the tool. Decoding happens on your device, so photographs of documents never leave it.
