Linked from

The 14 pages that link to PNG, each with the reason it gives.

• RGB color modelBroader topic: PNG files can store RGB pixel samples, optionally with an alpha channel.

• Data compressionCompared with: It preserves exact pixel values where JPEG's lossy encoding does not.

• Digital imageBroader topic: PNG preserves exact pixel values, unlike lossy photographic compression.

• Lossless compressionBroader topic: Its filtering and DEFLATE stages preserve image pixels exactly.

• JPEGCompared with: PNG preserves exact pixel values, unlike JPEG’s lossy quantization.

• sRGBRelated: PNG images often use sRGB values and can include metadata identifying that color space.

• Color depthRelated: PNG encodes images at several pixel and component depths.

• Image compressionBroader topic: It preserves exact image data for graphics, text, and screenshots.

• Huffman codingRelated: PNG’s compressed image stream uses DEFLATE, which includes Huffman coding.

• Alpha compositingRelated: PNG commonly stores images whose alpha values are later used in compositing.

• GIFCompared with: PNG improves still-image color depth and transparency without GIF’s single transparent palette entry.

• Image file formatBroader topic: It suits graphics that need crisp edges, transparency, or exact pixel values.

• Microsoft PaintCompared with: PNG preserves exact pixel values and transparency that BMP may not retain compactly.

• RGBA color modelRelated: PNG commonly stores RGBA pixels for images with transparent regions.
