Understand the formats

JPG / JPEG

JPEG stores raster photographs with lossy compression. JPG and JPEG are two extensions for the same format.

Choose JPG for photographic images when a receiving app needs a widely supported format. Inspect fine text and edges after reducing quality.

JPG does not store transparent pixels. A PNG-to-JPG conversion must fill the background. Saving an existing JPG as PNG cannot restore detail already lost in the JPG.

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?

Represent a photo using shades of gray. Grayscale differs from thresholding into only black and white.

Input and result example

color photo → grayscale photo

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