Encoding and decoding run entirely in this browser without a backend API. Input is not uploaded or saved to the URL or local storage.
Frequently asked questions
Is Base64 encryption?
No. Base64 converts bytes into printable characters and anyone can decode it. It provides no confidentiality or authentication.
Does this tool support Chinese and emoji?
Yes. Base64 uses UTF-8 bytes, so Chinese, emoji, and other Unicode characters round-trip correctly.
When should I use URL encoding?
Use it when text needs to be placed in URL query parameters or path segments and spaces, Chinese characters, or reserved characters need escaping.
