Your question: How many Colours does PNG support?

PNG–8 supports 256 colors and 1-bit transparency, and PNG–24 supports 24-bits and 16.8 million colors. PNG supports scalable transparency (from opaque to completely transparent) via alpha channel.

Is PNG limited to 256 colors?

An 8-bit PNG (PNG-8) is limited to 256 colors or palette entries, while a 24-bit PNG (PNG-24) can contain more than 16 million different colors. 24-bit PNGs are better for more complicated images with increased levels of detail and color.

Does PNG support a wide range of Colours?

PNG was developed as an improved, non-patented replacement for Graphics Interchange Format (GIF). PNG supports palette-based images (with palettes of 24-bit RGB or 32-bit RGBA colors), grayscale images (with or without an alpha channel for transparency), and full-color non-palette-based RGB or RGBA images.

Is PNG a 8-bit color?

The PNG‑8 format uses 8‑bit color. Like the GIF format, PNG‑8 efficiently compresses areas of solid color while preserving sharp detail like those in line art, logos, or type.
