About PNG

PNG (Portable Network Graphics) was released in 1996 as an open standard and developed as a patent-free alternative to GIF after Unisys demanded licensing fees for the LZW algorithm used in GIF in 1994. PNG uses lossless compression based on the Deflate algorithm and supports up to 16 bits per channel as well as full-color transparency through a dedicated alpha channel. The format is particularly suited for graphics with sharp edges, text, logos, and screenshots – anywhere JPEG would produce artifacts through its lossy compression. PNG does not support animation; this gap is filled by the unofficial APNG format, which is supported by most browsers. The interlaced variant (Adam7) enables progressive loading where a coarse preview becomes visible even with minimal data transferred. PNG is the de facto standard for lossless web graphics and is supported by all browsers, operating systems, and image editing programs. For photography, however, PNG is inefficient since file sizes are significantly larger compared to JPEG or WebP, which is why PNG is primarily used for graphics and screenshots.

Why convert HEIC/HEIF → PNG?

HEIC (High Efficiency Image Container) is the default photo format on Apple devices since iOS 11. It uses HEVC compression, delivering excellent image quality at significantly smaller file sizes than JPG — typically 50% less storage. However, HEIC is not natively supported by many non-Apple platforms: older Windows versions before Windows 10, most Android devices without third-party apps, many image editors, and numerous social media platforms. Converting to PNG is essential when you need to display iPhone photos on Android devices, embed them in Windows applications, upload them to websites, or share them with people who don't use Apple devices. PNG is the universal format expected for email attachments and online applications.
