Base64 Encoder & Decoder
Base64 Encoder & Decoder
Encode UTF-8 text and files as Base64, or decode strings and data URIs back into text or files.
Key features
- Encodes UTF-8 text as standard Base64 or unpadded URL-safe Base64.
- Decodes standard and URL-safe Base64 strings into UTF-8 text.
- Reads files as raw Base64 and MIME-bearing data URIs.
- Restores Base64 or data URIs as downloadable files with image previews when applicable.
How to use
- Choose the Text or File tab.
- Provide the value to encode or paste Base64 to decode.
- Copy the result or download the restored file.
Examples
Convert files and data URIs
Create a Base64 data URI from a file or download Base64 data as a file again.
Privacy
Text encoding and file reading or restoration run in your browser; text-tab input and settings are kept in that browser's local storage.
Requirements
Large files can use substantial browser memory during Base64 conversion.
Common questions
- Are non-Latin text and emoji encoded correctly?
- Yes. Text is converted to UTF-8 bytes before Base64 encoding and restored as UTF-8 when decoded.
- Does it support URL-safe Base64?
- Text mode can produce URL-safe output, and the decoder normalizes URL-safe input containing - and _.
