About heic to png

PNG is the right target when you cannot afford a second round of lossy compression. HEIC is already a lossy format, so converting it to JPEG means the image is compressed twice — once by the phone, once by the converter. For a photograph viewed normally that is invisible. For an image you are going to edit, crop repeatedly, or feed into something else, each generation costs a little more detail, and PNG stops that chain by being lossless.

The practical cases are editing and compositing. A screenshot taken on an iPhone, a photograph destined for a design tool, an image that will be cropped and re-exported several times — all of these are better served by a lossless intermediate. So is anything with sharp edges: text in a photograph, a scanned receipt, a diagram captured with the camera. JPEG puts a faint halo around hard edges; PNG does not.

The trade is size, and it is not subtle. A twelve-megapixel photograph that is three megabytes as HEIC and four megabytes as JPEG can easily be twenty-five megabytes as PNG, because there is no lossy step doing the compression work. For a handful of images that does not matter. For four hundred holiday photographs it is the wrong choice and JPEG is the right one.

Decoding uses the same bundled libheif WebAssembly build as the rest of the HEIC tools here, running in this tab. Nothing is uploaded, which matters most for the photographs people convert for practical rather than sentimental reasons — documents, forms, and identity papers photographed with a phone because that was the fastest way to get them into a computer.
