Sequence logos are a graphical representation of an amino acid or nucleic acid multiple sequence alignment developed by Tom Schneider and Mike Stephens. Each logo consists of stacks of symbols, one stack for each position in the sequence. The overall height of the stack indicates the sequence conservation at that position, while the height of symbols within the stack indicates the relative frequency of each amino or nucleic acid at that position. In general, a sequence logo provides a richer and more precise description of, for example, a binding site, than would a consensus sequence.

WebLogo is based upon the programs alpro and makelogo, both of which are part of Tom Schneider's delila package. Many thanks are due to him for making this software freely available and for encouraging its use.
The Look & Feel of the sequence logo generation form was inspired by the GIF/PNG-Creator for 2D Plots of Chemical Structures.
