Frequently asked questions
Everything you need to know about the Base64 Tool.
Is the Base64 tool free to use?
Yes. The Base64 Encoder & Decoder is completely free, requires no account, and has no usage limits.
Does it support UTF-8 characters like Chinese and emoji?
Yes. Encoding is UTF-8 aware, so Chinese characters, accented letters, and emoji are handled correctly in both directions.
Can I copy the result with one click?
Yes. Both the encoded and decoded outputs have a one-click copy button that places the result on your clipboard.
Is my data sent to a server?
No. Encoding and decoding happen entirely in your browser. Your input is only stored in your browser's localStorage so it survives a page refresh — nothing is uploaded.
