pure JavaScript PNG decoder with very limited functionality and speed, using a new web standard Compression Streams API to decompress RFC1951 DEFLATE format
please select colored PNG image file with alpha channel and bit depth of 8 bits per channel, without palettes or interlaces
larger images may take significant amount of time (e.g. 800 x 600 took ~5s on my Ryzen 7 pc)
decode finished in seconds
