Convert HEIC to JPG Without Uploading Anything

Every popular 'free HEIC converter' works the same way: you upload your photos to someone's server, they convert, you download. That means your family photos sit, however briefly, on infrastructure you don't control. This page works differently — the HEIC decoder (libheif compiled to WebAssembly) is delivered to your browser and runs on your own machine, so the HEVC-compressed photo is unpacked and re-encoded as JPEG without a single byte crossing the network.

.heic, .heif — up to 200 MB. Processed locally; never uploaded.

How to convert HEIC to JPG Without Uploading Anything

  1. Load this page — the converter itself is downloaded, once, like any web page.
  2. Drop your .heic photos onto the box (you can even disconnect from the internet first).
  3. Set JPEG quality if the default 85% doesn't suit you.
  4. Click Convert and watch your browser's network tab if you're skeptical: nothing is sent.
  5. Download the JPGs straight from your own device's memory.

Frequently asked questions

How can I be sure nothing is uploaded?

Open your browser's developer tools (F12), switch to the Network tab, and convert a photo. You'll see no request carrying file data. Stronger still: load the page, turn off Wi-Fi, and the conversion still works.

Why do other converters need uploads at all?

Their conversion software runs on their servers, so your file has to travel there. Running the converter in the browser inverts that: the code comes to you, once, and the files stay put. It's also why there are no queues or daily limits here.

Is browser conversion slower than a server?

For a handful of photos it's usually faster end-to-end, because there's no upload wait — the HEVC decode of a typical iPhone photo takes a second or two on a modern laptop. Very large batches are where servers still win.

Does it work on photos from any iPhone?

Yes — any HEIC using the standard HEVC main profile, which covers every iPhone and iPad since iOS 11. Files saved in the newer 10-bit HDR flavor also decode, converted down to standard dynamic range JPEG.
