Base64 Decoder

Decode Base64 strings back into readable text so you can inspect or reuse the original content. This is commonly used when debugging API payloads, tokens, or encoded configuration values.

How to use the Base64 Decoder

  1. Paste the Base64 input.
  2. Click Decode.
  3. Copy the decoded output.

Common use cases

  • Inspecting encoded API responses.
  • Debugging tokens or headers that include Base64.
  • Recovering config values from encoded files.
  • Verifying data before storage or transmission.

Tips & notes

FAQ

What is Base64 encoding?
Base64 is a binary-to-text encoding scheme that represents data using ASCII characters.
Is Base64 encryption or secure?
No. Base64 is not encryption and provides no security. Anyone can decode it.
Does this support UTF-8 or Unicode?
Yes. The decoder supports UTF-8 and most Unicode text where possible.
Is my decoded data stored?
No. All decoding is done instantly and nothing is saved.
What if the input has no padding?
Many Base64 strings omit padding; the decoder will still attempt to parse them.
