Fun facts about Image Format Converter
- JPEG was created in 1992 by the Joint Photographic Experts Group — the name is an acronym of the committee that created it.
- PNG was created specifically as a patent-free alternative to GIF — the GIF patent (owned by Unisys) expired in 2004.
- WebP (created by Google in 2010) typically produces files 25-34% smaller than JPEG at equivalent quality — it's now supported by all major browsers.
- The GIF format supports only 256 colors per frame — which is why photographs look grainy as GIFs but logos and graphics look sharp.
- SVG (Scalable Vector Graphics) is an XML-based format that scales to any size without losing quality — perfect for logos, icons, and illustrations.
