Encoding Tools

File Encoding Converter

Convert files up to 2 MB into Base64 or Hex text.

Convert small files into text encodings for fixtures, API payloads, and debugging.

Common edge cases

Binary files can produce long encoded output. Use the copy button only after checking the output size.

base64 ./file.txt

Why is there a size limit?

The guardrail keeps the page responsive and avoids huge copy buffers.
