Question 1

Are my photos uploaded to a server?

Accepted Answer

No. The conversion runs entirely inside your browser using WebAssembly, so the images are never uploaded and never touch a server. You can even disconnect from the internet after the page loads and it will still work.

Question 2

What is a HEIC file, and why does my iPhone create them?

Accepted Answer

HEIC is the container Apple has used for camera photos since iOS 11. It stores the same picture in roughly half the space of a JPG, which is great for your storage and awkward everywhere else — plenty of Windows apps, older software, web forms and customer inboxes still cannot open one.

Question 3

Is this really free?

Accepted Answer

Yes — free, no account, no email, no watermark, and no cap on how many files you convert. The only real limit is your own device's memory, since everything is processed locally.

Question 4

Can I convert a lot of photos at once?

Accepted Answer

Yes. Drop in as many photos as you like (or a whole folder) and they are converted one after another, with a download button per file plus a "download all" that saves the finished batch.

Question 5

Will converting to JPG lose quality?

Accepted Answer

JPG is a lossy format, but at the default quality the difference is invisible in a normal photo. If you need a pixel-perfect copy — for example an image with text or a logo — use the PNG converter instead, which is lossless.

Question 6

Does it work on my phone?

Accepted Answer

Yes. It works in any modern browser on iPhone, iPad, Android, Mac and Windows. On Apple devices the browser can usually decode HEIC on its own, so conversion is near-instant and the extra decoder never has to download.

Question 7

What happens to the photo's location data?

Accepted Answer

Rotation is preserved, so portrait photos stay upright. Other embedded metadata — including GPS coordinates — is dropped during conversion. That is usually a good thing: it means you can share a job photo without also sharing exactly where it was taken.

Question 8

How do I stop my iPhone taking HEIC photos in the first place?

Accepted Answer

On your iPhone or iPad open Settings → Camera → Formats and choose "Most Compatible". New photos are then captured as JPG instead of HEIC. Photos already in your library stay HEIC, which is what this converter is for.
