SVG Tiny Portable/Secure
BIMI requires a 32 KB SVG Tiny image. Editing 99 KB SVG down to 32 KB is challenging.
- SVG - Scalable Vector Graphics
- SVG Tiny 1.2 (see w3.org/TR/SVGTiny12)
- SVG v2 (see w3.org/TR/SVG2)
After 2026 May layoff I proved my 2025 BIMI proposal.
I reduced the famous trademarked American Express Centurion emblem redrawn by Steven Noble (stevennobleillustrations.com) in 2015.
- 99 KB to 32 KB
Reduction methods:
- reduce path coordinates
- 41 KB cut
- 14,131 coordinates down to 5,529 (61% reduction)
- reduce decimal precision
- 14 KB cut
- round up/down
- remove hundrenth place
- ex, change 0.12345 into 0.12
- remove zeros
- 6 KB cut
- ex, change 0.1 into .1
- ex, change 1.0 into 1
- remove spaces
- 5 KB cut
- ex, 100 C 38.7 into 100C38.7
- remove extraneous data
- 1 KB cut
Future improvements would be to:
- scale viewbox to 7998 x 9998
- remove decimal point
- improve path precision
