About this tool
What is the Base64 Encoder and Decoder?
Base64 Encoder and Decoder is a free, browser-based developer utility for developers, API testers, students, support teams, and technical writers. Use it to encode UTF-8 text as Base64 or decode valid Base64 back to readable text. Start with plain text to encode or a valid Base64 string to decode; LiteTools gives you copy-ready Base64 or decoded UTF-8 text generated on your device. There is no account wall, so you can open the page and begin immediately.
The workspace is designed for a focused task instead of a complicated editing suite. Base64 is an encoding format rather than encryption, so never use it to hide passwords or confidential data. The page explains the result before you download or copy it, helping you decide whether it fits your final workflow. Browser processing is used where the tool supports it; AI-assisted tools clearly identify when a request may be sent to the selected model provider.
