About the SVGZ format
SVGZ — Compressed Scalable Vector Graphics
SVGZ is the gzip-compressed version of SVG. It offers the same infinite scalability and all SVG features while reducing file size by 50–80% through compression. Modern browsers and SVG viewers support SVGZ transparently, making it ideal for serving SVG assets on the web.
Common uses
- Web server SVG delivery with smaller bandwidth
- Compressed vector graphics for web performance
- Serving logos and icons with reduced file size
- SVG asset optimization in web production pipelines
About the OTB format
OTB — On-the-air Bitmap (Nokia)
OTB is a monochrome bitmap format originally used by Nokia feature phones for sending and receiving images over SMS (picture messages). It was a standard format in early mobile phones of the late 1990s and 2000s for simple graphics like logos and ringtone icons.
Common uses
- Nokia mobile phone picture message images
- Converting legacy feature phone graphics
- Historical mobile messaging image recovery
