What is JPG?
JPG (or JPEG) is a widely used raster image format optimized for photographs and realistic scenes. It uses lossy DCT-based compression with an adjustable quality setting and typically chroma subsampling (e.g., 4:2:0) to shrink file size by discarding imperceptible color detail. Standard JPGs are 8-bit per channel, usually in sRGB, and can be baseline or progressive for faster perceived loading on the web. The format supports EXIF metadata but not true transparency or layers, so it isn’t ideal for logos, text, or sharp line art. Use PNG or SVG for graphics, and WebP/AVIF for smaller, modern photos. To preserve quality, export at a higher quality value (e.g., 85–92) and avoid repeated re-saves, which accumulate compression artifacts.
What is PNG?
PNG (Portable Network Graphics) is a lossless raster image format designed as an open replacement for GIF. A .png uses DEFLATE compression, keeping file sizes small without sacrificing pixel fidelity, and it supports 8-bit palette images or 24/48-bit truecolor. Crucially, PNG includes full alpha transparency (up to 16-bit), enabling smooth edges, soft drop-shadows, and overlays—something JPG cannot do. Features include embedded color profiles (sRGB/ICC), gamma information for consistent brightness, and Adam7 interlacing for progressive display on the web. PNG is ideal for UI assets, logos, icons, diagrams, and screenshots; for photographs, JPG/WEBP/AVIF often yield smaller files. Standard PNG stores a single image; animated PNGs (APNG) extend the format for sequences. You can create or edit PNG with Photoshop, GIMP, Affinity Photo, and most graphics tools.
