Base64 Encoder/Decoder
Encode text to Base64 or decode Base64 back to text (UTF-8, URL-safe option). Your text stays in your browser and is never uploaded.
How to use
- Choose Encode or Decode.
- Paste your text or Base64 string.
- Copy the result.
Notes and limitations
- Text is handled as UTF-8, so emoji and non-English characters work.
- This tool converts text only. Decoding data that is not valid UTF-8 text (such as an image) is reported as an error instead of showing garbage.
- Whitespace in Base64 input is ignored; URL-safe input (- and _) is accepted when decoding.
FAQ
Is Base64 encryption?
No. Base64 is an encoding, not encryption. Anyone can decode it, so never use it to protect secrets.
