Are my HEIC files uploaded anywhere?

No. This conversion runs entirely inside your browser, so the file never leaves your device. You can confirm it yourself: open the network tab of your browser's developer tools and watch that nothing is sent while the file converts.

Should I convert an iPhone photo to PNG or JPG?

JPG, almost always — it is a fraction of the size and the difference is invisible on a photograph. Choose PNG when the image is a screenshot, contains text or line art, or is going to be edited and saved repeatedly.

PNG is lossless, so does the picture stay perfect?

The PNG stores exactly what came out of the decoder, with no further loss. But the HEIC itself was already compressed by the phone, so this preserves what you have rather than recovering what the sensor saw. Lossless from here on, not lossless all the way back.

Why is the PNG five times bigger than the HEIC?

Because PNG stores photographs very inefficiently — it was designed for flat colour and sharp edges, not for the continuous tone of a camera image. HEIC is roughly twice as efficient as JPG and PNG is several times worse, so the two effects compound. That size is the price of not losing anything further.

Does it keep transparency?

There is none to keep. Camera images are fully opaque, so this matters only if the HEIC came from somewhere other than a camera.

What happens to the location data?

It is not carried over. The conversion works from decoded pixels, so GPS coordinates, camera model and timestamps do not survive it. For anything you are about to share, that is usually welcome.

Are my photos uploaded?

No. The decoder runs inside your browser and the image never leaves your device — which for the contents of a personal camera roll is the only arrangement that makes sense.

Convert HEIC to PNG

Up to 3 files at once, 100 with Pro. Mixed formats are fine.

Converting HEIC to PNG keeps every pixel the decoder produced, which is the right trade for a screenshot or an image you are about to edit — and the wrong one for a holiday photograph, where the PNG will be five to ten times larger for no visible gain. Drop the file above; it converts on your own device, with nothing uploaded.

HEIC to PNG or HEIC to JPG?

Most people converting an iPhone image want JPG, and if you arrived here without a specific reason, that is probably the page you want instead. PNG is the deliberate choice, and it is worth being clear about when it is the correct one, because the file you get will be several times larger and for a photograph you will see no benefit at all.

PNG when the image is going to be edited

Every save as JPG discards a little more detail, so an image that will be cropped, colour-corrected and saved several times accumulates damage with each pass. PNG does not: once the picture is decoded, it is stored exactly, and it stays exactly that through however many rounds of editing. If the image is going into a design tool and coming out again, start with PNG.

PNG for screenshots and anything with text

Not everything an iPhone saves as HEIC is a photograph. Screenshots, images with text in them, diagrams, anything with hard edges between flat areas of colour — these are what PNG was built for, and what JPG handles worst.

JPG compression smears the boundary between a letter and its background, which is visible on a screenshot at a glance and impossible to remove afterwards. For those, PNG is not a preference, it is the right answer.

What "lossless" means and does not mean here

The PNG stores exactly what the decoder produced, with nothing lost from that point on. But your phone already compressed the picture when it saved the HEIC, and no conversion can undo that. This preserves what you have; it does not recover what the sensor originally saw.

If you want the full data, iPhones can shoot in ProRAW, and that is a decision made before the photograph rather than after.

Why the PNG is so much larger

Expect five to ten times the size of the HEIC, sometimes more. That is not inefficiency in the converter — it is PNG being a poor fit for continuous tone. HEIC is roughly twice as efficient as JPG, and PNG for a photograph is several times worse than JPG, so the two effects compound. A 2 MB photo becoming a 15 MB PNG is entirely normal.

As with every image conversion here, this runs on your own machine. The decoder is downloaded to your browser and the photograph never moves. The metadata does not survive, so location and camera details are gone from the result; for anything you are about to send to somebody, that is a feature.

HEIC vs PNG: exactness bought with size

HEIC compared with PNG
	HEIC	PNG
Full name	High Efficiency Image Container	Portable Network Graphics
File extension	.heic	.png
Media type	image/heic	image/png
Compression	Lossy — file size is bought with quality	Lossless — nothing is discarded

Quality: Nothing is lost. The result holds exactly the same picture, text or data as the original.
Where it runs: This conversion runs inside your browser. Your file is never uploaded, and it works with the network disconnected.
