Base64 Encoder & Decoder — Encode & Decode Text Online

About This Tool

Base64 Encoding and Decoding converts binary or text data into ASCII characters for safe web transmission. Our converter is fully compatible with standard UTF-8 text (including emojis and foreign symbols) and includes a toggle for URL-Safe Base64 format (using '-' and '_' instead of '+' and '/' with trimmed padding).

How to Use

1. Select the operational mode: either "Encode Text" or "Decode Base64".
2. Type or paste your source text into the input container.
3. Toggle the "URL-Safe" option if you are preparing Base64 strings for URLs or API routes.
4. View the translated output in the opposite pane instantly.
5. Verify any error banners indicating malformed input while in Decoding mode.
