No black box

How this tool handles the input

The browser encodes text as UTF-8 bytes and maps those bytes to the standard Base64 alphabet with padding.

Before you start

What you need

Text whose byte representation you need in standard Base64.

What you get

What the page gives back

A Base64 text value that can be copied or downloaded.

Keep in mind

Use the result responsibly

Base64 is reversible encoding, not encryption, signing, hashing, or secret protection.

Practical uses

Where this tool earns its place

  1. Prepare a small text value for a data URI.
  2. Inspect UTF-8-to-byte encoding behavior.
  3. Create a test fixture for a Base64 field.

Verified data boundary

Source text stays on this page.

The published contract marks these tools as client-only processing. Nirmion uses the API only to confirm that this workspace is enabled in MySQL; source values and results are not sent to Flask.
