Sequence Logo Maker

About the tool

Sequence logos are graphical representations of the patterns within a multiple sequence alignment. They are used to represent the consensus sequence of a set of aligned sequences, typically protein or DNA sequences, and illustrate sequence conservation.

This tool is my implementation of the sequence logo generator that allows you to create sequence logo diagrams online. It automatically detects the type (nucleic acid or protein) of the input sequence alignment and runs locally in your browser.

Try it out by pasting or entering a FASTA alignment below.
