HEIC to PNG Converter — Free, Private, No Upload
Turn HEIC photos into lossless PNGs, right on your device. Every pixel is kept, nothing is uploaded, and there are no limits or signups.
Reach for PNG when you want a pristine, editable copy of a HEIC photo rather than the smallest possible file. PNG is lossless, so nothing is thrown away in the conversion — handy if you plan to retouch the image or drop it into design software. The trade-off is size: a photographic PNG is usually larger than both the original HEIC and a JPG.
How to convert HEIC to PNG
- 1 Add your HEIC files — drag them onto the box above, or tap to choose them from your device.
- 2 The format is already set to PNG for a lossless copy — switch to JPG or WebP any time.
- 3 Save each PNG on its own, or download the whole set as one .zip. Everything stayed local.
Yes — because nothing is uploaded.
Most converters send your photos to a server you know nothing about. Filexum can't, because it never asks for them: the conversion runs inside your browser, on your own device. You don't have to take our word for it — open your browser's Network tab and watch it stay empty, or turn off Wi-Fi and convert anyway.
- Your photos are uploaded to a stranger's server
- Files may be kept, cached or logged after conversion
- Ads, watermarks, sign-ups or daily limits
- Needs a working internet connection
- Photos are converted on your device — nothing is uploaded
- There is no server, so there is nothing to store or leak
- No ads, no watermark, no signup, no limits
- Works offline — try it in airplane mode
Why HEIC?
HEIC is the format Apple has used for iPhone and iPad photos since iOS 11 in 2017. It stores a still image inside the HEIF container using HEVC (H.265) compression — the same technology behind 4K video — which lets it hold a photo at roughly half the size of a JPG while keeping more detail, wider colour and extras like Live Photos and depth maps.
The catch is reach. Windows, many Android phones, older photo software and plenty of websites still can't open a .heic file without an extra plugin. Converting to a more universal format is usually the quickest fix — and on this page it happens entirely on your device, so the photos never leave it.
Why PNG?
PNG arrived in 1996 as a free, patent-unencumbered image format, and it does something JPG can't: it is lossless. Every pixel is preserved exactly, and it supports full alpha transparency — which makes it the go-to format for screenshots, logos, diagrams and any image with sharp edges or text.
That perfect quality has a cost in size: a photographic PNG can be several times larger than the same picture as a JPG. If you want a pristine, editable copy of a HEIC photo — or you need transparency — PNG is the right target. For small, shareable files, JPG or WebP will serve you better.

HEIC to PNG — frequently asked
Is converting HEIC to PNG here private?
Completely. The image is decoded and re-saved by code running in your own browser, so your HEIC never travels anywhere. Airplane mode is a good way to prove it to yourself.
Where do my HEIC files actually go?
Nowhere. They stay on your device from start to finish — there is no upload step and no server receiving them, so nothing about them is transmitted.
Why is my PNG larger than the original HEIC?
PNG is lossless, so it stores every pixel exactly instead of compressing detail away like HEIC does. For a photo that means a bigger file. If size matters more than a perfect copy, convert to JPG or WebP instead.
Does the PNG keep transparency?
PNG supports full alpha transparency, but iPhone HEIC photos are normally solid rectangles with no transparent areas, so the result is simply a lossless copy of the photo.
Is this HEIC to PNG converter free?
Yes, entirely free — no account, no watermark stamped on the PNG, and no ads. With no servers to run, there is simply nothing to charge for.
Can I convert a whole folder of HEIC photos to PNG?
Yes. Add as many as you like and download every PNG together in one .zip; the practical ceiling is just your device's memory.
Which devices does this work on?
Any with a reasonably current browser — iPhone, iPad, Android, Windows and Mac — using Safari, Chrome, Firefox or Edge.
