How to decode Base64

Round-trip a Base64 string back to plain text, or encode text for safe transport.

Base64 is the way to push arbitrary bytes through a text-only channel. The Base64 tool round-trips both directions.

Steps

  1. Open the Base64 Encoder / Decoder.
  2. Choose Decode or Encode.
  3. Paste your input.
  4. Copy the output.

Notes

  • Padding (= at the end) is required for standard Base64 — most decoders are permissive, but if you see weird trailing characters, padding is the first thing to check.
  • URL-safe Base64 replaces + with - and / with _. We auto-detect both.

This is a placeholder. Full guide coming soon.
