Free Online HEIC to PNG Converter

The HEIC is a modern image format with the final specification completed in 2015. The format is a container format which whilst mostly used for storing image data the format can actually support video, audio and text data streams.

HEIC files are binary in nature and offer an alternative to existing digital photo formats such as JPEG featuring better compression whilst retaining comparable image quality. In some cases the file size can be 50% that of the equivalent JPG file.

The PNG graphics file format is a commonly used format for storing 2D images which can be highly compressed by the use a palette if the image has a sufficiently low number of colors (256 colors in general). The PNG file is then further compressed using the DEFLATE compression algorithm to ensure small file sizes that are fast to download.

PNG files are seen as the logical successor to the GIF image file format and was devised in the mid-1990's as a superior format to GIF. PNG files are generally used for company logos, icons and other non-photographic image content. Saving a digital photo in the PNG format will create a much larger file than an equivalent JPG image hence the PNG format being unsuitable for most digital photo content.
