Favicons made by shrinking a big bitmap go muddy at 16 pixels; favicons rendered from vector do not. Starting from an SVG, each required size, 16, 32, 48 and 256 pixels, is rasterised independently from the original shapes, giving the crispest result each size allows. The four pack into one standard ICO that serves browser tabs, Windows shortcuts and pinned sites alike. Simple, bold marks survive the smallest sizes best, as they always have.
Questions
Why is vector source better for favicons?
Each size renders from geometry instead of resampled pixels, so the 16-pixel version is as sharp as 16 pixels permit.
My logo has fine detail. Will it survive?
At 16 pixels, detail dies regardless of tooling; that is design, not conversion. Consider a simplified mark for the smallest sizes.
Do modern sites still need ICO?
A favicon.ico in the root remains the works-everywhere baseline that shortcuts and legacy contexts still request.
