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?

Restore an image from Base64 image data. Base64 encoding of ordinary text is not an image.

Examples illustrate the workflow; actual size, support and recognition depend on the source and settings.
