What Base64 Encoder & Decoder does
Encode text to Base64 or decode Base64 back to text. The page concentrates on this exact job, keeps the controls beside the result, and reports invalid or incomplete input instead of silently inventing an answer.
Parsing and conversion happen locally with browser JavaScript. Secrets should still be removed because copied output can remain in your clipboard history. For Base64 Encoder & Decoder, the operation is specifically to encode text to Base64 or decode Base64 back to text.
Worked example
Encode UTF-8 text "Hello, World!". The standard Base64 output is SGVsbG8sIFdvcmxkIQ==. Under URL-safe mode, + and / are converted to - and _ with optional padding stripping.
How to verify the result
Test a small known sample first, then inspect quotes, escapes, dates, and character encoding in the output. The final Base64 Encoder & Decoder output should visibly match this goal: Encode text to Base64 or decode Base64 back to text.
Important limitations
Base64 expands raw payload size by approximately 33% (4 output characters for every 3 raw bytes). It provides encoding, not encryption or password secrecy.
