JWT payloads, data URIs, config values and API responses all hide readable content behind Base64. You cannot debug what you cannot read.
Paste a Base64 string to recover the original text, with UTF-8 sequences reassembled properly.
How to use the Base64 Decoder
- Paste the Base64 string, without any data:...;base64, prefix.
- Read the decoded text.
- If the result is unreadable, the input was binary data rather than text — an image or compressed payload.
- Copy the decoded output.
