Convert HEIC to PNG online, for free.
High Efficiency Image Codec (HEIC) is a variant of HEIF that Apple adopted in 2017 when iOS 11 was introduced. The main advantage of HEIC is that it requires less space than JPEG (JPG) with no diminishment of image quality. Both HEIC and HEIF are based on High Efficiency Video Coding (HEVC).
HEIC opens by default on Apple iOS and related applications and operating systems, such as macOS, iOS 11, macOS High Sierra, Apple Photos, and Apple Preview. Android OS also supports HEIC. On Microsoft Windows, open HEIC with Zoner Photo Studio.
The best alternative program for opening HEIC is XnView MP, which works across platforms.

Portable Network Graphics (PNG) is a raster-based file type that compresses images for portability. PNG images can have RGB or RGBA colors and support transparency, which makes them perfect for use in icons, or graphic designs. PNG also supports animations with better transparency (try our GIF to APNG). The benefits of using PNG are Plus, PNG is an open format that uses lossless compression.
Generally, PNG files will open in your operating system’s default image viewer. PNG files are also easily viewable on all web browsers. If you are having trouble opening PNG files, use our PNG to JPG, PNG to WebP, or PNG to BMP converters.
Alternative programs such as GIMP or Adobe Photoshop are useful for opening and editing PNG files. PNG files are a bit larger than other file types, so exercise caution when adding them to a web page. One interesting feature of PNG files is the ability to create transparency in the image, particularly a transparent background. To accomplish this, try this transparent background tool. To resize PNG images you can use our Image Resizer tool.
