Base64 Encoder and Decoder
Encode text to Base64 or decode it back, with unicode handled properly.
Base64 shows up everywhere in development: basic auth headers, JWT payloads, data URIs, config values that had to survive a transport that only carries ASCII. Decoding one by hand is not an option and running it through a command line is not always convenient. Paste it here and read it immediately — or go the other way and encode a string ready to embed.
How to Use the Base64 Encoder / Decoder
- 1
Pick a direction: text to Base64, or Base64 to text.
- 2
Paste your input on the left.
- 3
The converted result appears instantly on the right.
- 4
Copy it into your header, config file or request.
Why Use TextsPro
This runs entirely in your browser, which matters more for Base64 than for most conversions: the strings people decode are frequently tokens, auth headers and config secrets, and pasting those into a server-side tool means handing them to someone else. Unicode is handled correctly in both directions by encoding to UTF-8 bytes first, which is where the naive browser approach falls over and throws on any non-Latin character. The decoder also accepts URL-safe Base64 with dashes and underscores, so JWT segments decode without you having to convert them first.
