Base64 Converter + Repair

This tool normalizes payloads, fixes padding, validates decode, and returns a canonical Base64 output.

What It Does

The repair flow applies three core steps: normalize noisy input, correct padding/invalid characters, and validate by decoding and re-encoding to canonical Base64.

Why It Matters

Integration failures often come from malformed Base64 payloads: URL-safe variants, missing padding, hidden whitespace, or broken data URIs. This tool removes that friction quickly.

How To Use

  • Paste payload in the input field.
  • Use Repair Base64 for broken inputs.
  • Use Encode text for plain text conversion.
  • Use Decode Base64 to read decoded text/bytes.
