Base64 Encoder & Decoder | Merto Tools

Base64 encoder & decoder

Turn plain text into Base64 and back again, ideal for quick checks when you are wiring APIs or reviewing configs.

Coming soon

We are finishing a client-side encoder so nothing sensitive leaves your session. You will be able to paste text or small files, copy the result, and switch direction without reloading the page.

Until this ships, your editor or terminal base64 commands still work, and we will match that behaviour with clearer validation and error messages in the UI.
