Markdown compression & quality
Markdown compression: none or container. Lossless (or non-destructive packaging) keeps reconstructable data — size savings come from packing efficiency, not throwing detail away. Typical size profile: Tiny text files. Quality note: Excellent for technical writing; limited page design control
Quality: Excellent for technical writing; limited page design control
Typical size: Tiny text files
Transparency & animation
Markdown does not support an alpha channel. Convert to PNG, WebP, AVIF, or SVG when you need transparent backgrounds.
Markdown is a still-media or non-animated format in typical use. Use GIF, APNG, video, or animated WebP when you need motion.
Markdown metadata
No structured metadata standard; encoding and line endings are the practical concerns.
