How to use this tool well
Use this converter for safe text snippets, test fixtures, JWT segments, data URI checks, and API examples that need quick Base64 encoding or decoding.
- Choose encode when you have plain text and need a Base64 string for a test payload.
- Choose decode when you receive a Base64 value and need to confirm the readable text before using it.
- For binary files, verify the source application generated the Base64 correctly before pasting large content.
