About yEnc Encoder & Decoder
Encodings turn data into a different alphabet so it can travel safely through systems that only accept certain characters. Base64 is the best known, but dozens of others exist, each with its own trade-off between size, readability and safety.
This tool does one encoding well. It shows the result as you work, reports clear errors for invalid input and never sends your data anywhere.

No. Encoding only changes how data is written and anyone can reverse it. It gives no secrecy, so never use it to protect passwords or private data.
Why does my encoded text look longer than the original?
Most encodings add overhead. Base64 grows data by about 33%, Base32 by about 60% and hex by 100%, because each output character carries fewer bits.
Does yEnc Encoder & Decoder support emoji and non-English text?
Yes. Text is converted to UTF-8 bytes first, so every character is encoded and decoded correctly.
Why does decoding fail or show strange characters?
The input may contain characters outside the alphabet, be cut off, or be a different variant of the encoding. Decoded binary data such as an image also shows as garbled text, because it is not text.
