What “lossless” really means for your photo
PNG is a lossless format, and that single property is the whole reason to choose it. When an image is saved as PNG, every pixel is stored exactly as it was — no detail is approximated, blurred, or thrown away to save space. You can open that PNG, edit it, save it again, and repeat that cycle a hundred times without the image degrading. JPG cannot do this: each save discards a little information and bakes in compression artifacts that accumulate over time.
When you extract a Live Photo's still as PNG, you are capturing the camera's full-resolution key frame and freezing it with zero quality loss from that point forward. The trade-off is file size — a lossless PNG is meaningfully larger than the same image as JPG, often several times larger — but in exchange you get a master-quality copy that's perfect as a starting point for any serious work.
When PNG is the right choice (and when it isn't)
Reach for PNG whenever the image is going to be worked on rather than just viewed. Photo editing and retouching, graphic design, compositing, printing at large sizes, and long-term archival all benefit from a lossless master, because every later edit starts from clean, artifact-free pixels. PNG is also the format of choice when an image needs sharp edges and flat color areas to stay crisp — text overlays, screenshots, logos, and graphics.
PNG is the wrong choice when file size or universal lightness matters more than perfection. For texting a photo, posting to social media, attaching to an email, or uploading to a marketplace, the large PNG is overkill and a JPG is the smarter pick — smaller, just as universal, and visually identical for viewing. If that's your goal, use our Live Photo to JPG tool. And for web pages where load speed counts, our Live Photo to WebP tool gives lossless-or-lossy options at smaller sizes.
PNG vs the original HEIC still
The still inside a Live Photo is normally stored as HEIC. HEIC is itself a high-efficiency format, but it has two issues for serious use: it is lossy (it has already discarded some data to stay small), and it is Apple-first, so many editors, printers, and operating systems can't open it. Converting that still to PNG doesn't magically restore detail HEIC already dropped, but it does give you a universal, lossless container from which no further quality is lost — which is exactly what you want before you start editing.
Think of it this way: HEIC is a compact original, and PNG is the workshop copy. Once your still is a PNG, it opens in Photoshop, GIMP, Affinity, Figma, Windows, Linux, and every browser, and you can edit and re-save it freely without the gradual decay that would haunt a JPG workflow. That combination of universal support and lossless preservation is why design and print workflows standardize on PNG.
Getting the highest-quality still, not a video grab
A Live Photo bundles a full-resolution still with a short three-second video, and there's a real quality gap between them. The camera's key still is captured at the full sensor resolution and is free of motion blur, while individual frames pulled from the companion video are softer and more compressed. For a lossless PNG to be worth its larger size, it should start from the best source — and that means the key still, not a frame of the playback.
This converter extracts the full-resolution key still and encodes it directly to PNG, so the lossless quality you pay for in file size is genuinely there in the pixels. Taking a screenshot of a Live Photo and saving that as PNG would technically produce a PNG, but it would be a lossless copy of a low-quality, screen-resolution image — the worst of both worlds. Starting from the real still avoids that trap entirely.
Private by design, and ready for batches
All processing runs locally. The Live Photo is opened, the still extracted, and the PNG encoded entirely inside your browser using WebAssembly, so nothing is ever uploaded to a server. Your photos can't be seen, stored, or leaked by us because they never leave your device — and the tool keeps working offline once loaded, with no upload-imposed size cap, which is handy since PNGs are large.
If you're preparing a set of stills for a design project or an archive, you don't have to convert one at a time. Select multiple Live Photos and download them together as a ZIP, or use our dedicated Batch Converter for large jobs. Everything runs on your own hardware, so even a big batch of high-resolution PNGs finishes quickly with no server queue.
