What Base64 Encoder/Decoder helps with

Encode plain text to Base64 or decode Base64 back to readable text. Use it to encode sample text for tests, decode API examples, inspect basic payloads, or convert strings while debugging integrations. Key capabilities on this page include encode text, decode strings, browser-only processing.

Before you start

Confirm whether the value is plain text or Base64. Avoid pasting real credentials, signed tokens, or private binary data into examples.

Step-by-step workflow

Paste the source value, choose Encode or Decode, review the result, and copy the converted string into your local test or documentation.

Quality checks

Decoded output should be readable text. If it looks broken, the input may be binary data, URL-safe Base64, missing padding, or not Base64 at all.

Privacy, processing, and limits

This tool runs in your browser, so the input is processed locally on your device. Base64 is an encoding format, not encryption. Anyone with the value can decode it, so do not use it to hide secrets.
