How to use HEIC to PNG

- Check the image preview and dimensions, then download your PNG. The PNG may be larger than the original HEIC.
Useful next steps
What to expect
Convert a HEIC photo to PNG. Decode the primary still image in your browser, with orientation applied. Your file is not uploaded. Up to 20 MiB and 40 megapixels. Exports an 8-bit image without original metadata; HDR, depth maps and additional frames are not preserved. PNG files can be larger than the original.
