Convert HEIC photos from your iPhone or iPad to PNG, a lossless format every editor and app can open. Your photos are converted on your device and never uploaded.
PNG is a lossless format: the converter saves every pixel of the decoded photo without adding any compression artifacts. That makes PNG the better choice when you're going to edit, crop or retouch the photo, because each later save in a lossless format doesn't reduce the quality further.
PNG also supports transparency, so the rare HEIC files that contain a transparent background, such as cut-out subjects, keep it.
HEIC compresses photos very efficiently and PNG doesn't compress photos well, so a PNG is usually many times larger than the HEIC original, often ten times or more. That's normal for a lossless copy of a photo. If you only need to share or upload the photo, HEIC to JPG gives you a much smaller file that looks the same.
The photos are decoded with libheif, an open-source HEIF decoder, right in your browser. iPhones record photos in the wide Display P3 color space; the converter translates them to standard sRGB so the PNG shows the right colors everywhere, at the original resolution.
