FileTools

Decode Base64 or a data URL into a downloadable file.

How it works

  • Enter or paste the content
  • Select “Decode file” and let your browser process it
  • Review the result and download it to your device

Why use FileTools for base64 to file?

Base64 to file decodes text back into binary bytes and packages them as a browser download. A complete data URL can supply its own media type; raw Base64 uses the fallback type and filename you enter.

Best suited for

Recovering test fixtures, saving API payloads, decoding embedded assets, and checking Base64 output.

Input and output

Input: Raw Base64 or a valid data URL, plus an output filename when needed.

Output: One downloadable file containing the decoded bytes.

Known limitation

Decoding cannot identify whether bytes form a safe or valid document. Incorrect MIME types or extensions can confuse other applications.

Practical tips

  • Use the filename extension and MIME type expected by the source system.
  • Scan or inspect decoded files from untrusted sources before opening them in another application.
