Does Base64 compress or encrypt text?
No. Base64 is a reversible text encoding and usually makes data larger. It provides neither compression nor confidentiality.
Base64 Encoder & Decoder
Convert UTF-8 text and standard Base64 in either direction with strict validation, copy and text-download controls, and no server upload.
Standard Base64 and UTF-8 text are supported. Decoded data is limited to 1 MiB.
Base64 output
Output is generated only when you run the current conversion.
Conversion happens entirely in your browser. Input and output are not uploaded or stored by Tool Teaze.
What this tool does
This utility converts Unicode text to standard Base64 and decodes standard Base64 back to valid UTF-8 text using browser-native APIs.
How to use it

FAQ
Does it support emoji and non-Latin text?
Yes. Text is encoded and decoded as UTF-8, including emoji, CJK text and combining characters.
Which Base64 variant is supported?
The decoder accepts the standard AβZ, aβz, 0β9, plus and slash alphabet, with optional padding and ASCII whitespace. URL-safe Base64 is not converted automatically.
What is the size limit?
Source or decoded UTF-8 data is limited to 1 MiB to bound browser memory and clipboard work.
Is my content uploaded or saved?
No. Conversion runs locally in your browser, and Tool Teaze does not upload or persist the input or output.
