HEIC is the format iPhones and iPads use for photos by default. It is efficient, but Windows, many websites, email clients and older apps cannot open it. Converting HEIC to PNG gives you an exact, lossless copy that keeps transparency.
PNG is lossless, so every pixel is kept exactly, and it supports transparency. That makes it the safe choice for screenshots, logos and graphics. PNG files are larger than JPG or WebP for photographs, so use it when exactness or transparency matters more than size. This converter reads HEIC in your browser. Safari handles it directly. Other browsers download a small decoder the first time you add a HEIC file, then convert on your device. Large photos can take a moment.
PNG is lossless, so there is no quality setting. The pixels are kept as they are. The pixel dimensions follow the original, each file keeps its name with only the extension swapped, and no metadata or watermark is added. Everything runs in your browser, so your images are never uploaded.
Tip: JPG is what most people want from an iPhone photo, because everything opens it. Choose High or Max quality to keep the photo as close to the original as possible.
Not with PNG. It is lossless, so the pixels are kept exactly as they are.
Photos have no transparency. If a HEIC file has an alpha channel, PNG and WebP keep it, and JPG fills it with white.
No. The converted image contains only the picture, so location and camera details from the original are not copied into it.
Yes. Add them all, convert once and download a single ZIP. Only the extension changes. A photo named IMG_1234.heic becomes IMG_1234.png.
No. The conversion happens in your browser and the files never leave your device.
