Image Formats.

An image format determines how visual information is represented and delivered, but it does not describe every decision that created the image. PNG, JPEG, and SVG have different strengths, while dimensions, transparency, source quality, and rendering history remain separate concerns. A lossless file can contain a heavily cropped or previously compressed picture. A vector container can include a raster photograph. Choose a format by the properties the next stage needs, rather than assuming that an extension guarantees a particular level of quality.

This archive focuses on practical comparisons: photographic detail, crisp graphic edges, alpha transparency, scalable shapes, and predictable output. The image frame overview connects format selection to cropping and composition. As you read, assemble a small test set containing a photograph, a screenshot, a transparent logo, and a text-heavy graphic. Compare the actual exports at their intended display sizes, including file size and edge appearance, before selecting a default for every asset.
