Question 1

Are my files uploaded anywhere?

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?

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

Why is my PNG bigger than the original HEIC?

Accepted Answer

Because PNG is lossless and HEIC is not. HEIC throws away detail your eye will not miss in order to shrink the file; PNG keeps every pixel exactly. Expect a PNG to be several times larger than the HEIC it came from. If size matters more than perfect fidelity, convert to JPG or WebP instead.

Question 4

Should I use PNG or JPG?

Accepted Answer

Use PNG when the image contains text, screenshots, diagrams or transparency, or when it needs to stay exact. Use JPG for ordinary camera photos, where it looks the same but produces a much smaller file.

Question 5

Is it free, and is there a limit?

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 6

Can I convert several files 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 7

Does it work on iPhone and Android?

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 8

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.
