Common Base64 workflows
Base64 represents bytes and adds size; it does not encrypt them. Decode the byte sequence first, then choose text or a binary file based on its actual content rather than assuming every result is UTF-8.

- ASCII Converter — Convert ASCII text to decimal codes, hex, binary or Base64 and back.
- Byte Encoder — Transcode bytes between UTF-8, ASCII, hex, binary, Base64 and decimal notation.
- SHA-3 & Extended Hash Generator — Compute SHA-3, SHAKE, SHA-224, SHA-512 variants and CRC-16/ARC from text or bytes.
- Protobuf Wire Decoder — Inspect Protobuf fields and gRPC frames without a schema.
Review the result before using it
Each tool explains its accepted input, supported options and limits. Keep the original and verify important output in the application that will consume it.
Frequently asked questions
How do I choose a Base64 tool?
Base64 represents bytes and adds size; it does not encrypt them. Decode the byte sequence first, then choose text or a binary file based on its actual content rather than assuming every result is UTF-8.
Can the same tool appear in more than one topic?
Yes. Tools are listed by supported formats and tasks as well as their main category. Each tool has one page and processing runs locally; explicit API clients connect only to endpoints you choose.
