Understand the formats

PNG

PNG stores raster images with lossless compression and supports an alpha channel for transparency.

Use PNG for screenshots, diagrams and interface graphics. Check the pixel dimensions before placing it in a print document.

A PNG file can be larger than a JPG of a photograph. Browser processing can change metadata and color profiles; lossless compression does not guarantee that every source property is retained.

When is this useful?

Visualize audio amplitude for reference or documentation. This is not speech transcription.
