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 JPG/WEBP/BMP/GIF/HEIC → PNG?
The universal image converter processes any input format and converts it uniformly — ideal when you need to bring images from various sources (smartphone, scanner, screenshots, design tools) into a consistent format. Converting to PNG is the fastest solution to prepare images for web, print, or mobile use. PNG is the universal target format for any type of image processing and ensures consistent display across all platforms. PNG supports lossless compression and alpha transparency, making it ideal for graphics, screenshots, and images with transparent areas.
