Why does decoded text look broken for some characters?
Some payloads were encoded from UTF-8 bytes. This tool handles common UTF-8 text, but malformed source data can still decode into unreadable output.
Base64 Encode / Decode
Encode text to Base64 or decode Base64 back to plain text.
Base64 Workflow Notes
Base64 is useful when text must travel through systems that only accept ASCII-safe payloads, such as headers, config fields, or legacy transports.
- Encode UTF-8 text before embedding into transport layers that expect plain bytes.
- Decode incoming payloads quickly when debugging integrations.
- Use hashing tools after decoding if you need deterministic checks.

Base64 Encoder FAQ
Is Base64 encryption?
No. Base64 is an encoding format, not encryption. Anyone can decode it without a key.
Should I remove line breaks in Base64 output?
Many APIs expect a single-line string. If your target supports wrapped output, line breaks can still be valid.
