Base64 Encoder/Decoder: Pack an Image Into a Line of Text

Ever seen an entire image turned into a long string of characters? Inlined in an email signature, embedded in front-end code, or carried as part of data transfer — that's what Base64 does.

Base64 Encoder/Decoder both encodes and decodes ordinary text, and converts images to Base64 strings or back, letting you carry assets without depending on external links.

It's especially useful when writing HTML emails, doing lightweight front-end asset inlining, or handling certain API signatures.

When you want a letter or a snippet of code to be truly self-contained, Base64 is the key that packs an image into text. Bookmark it and conversion is done in seconds whenever needed.
