How to use Base64 Decode
- 1Paste a Base64 string into the decoder — line breaks and = padding are handled automatically.
- 2The decoder auto-detects URL-safe variants (- and _) and converts back.
- 3Pick the output format: UTF-8 text (default) or download as a binary file (image, PDF, audio).
- 4If the Base64 starts with data:image/...;base64, the tool decodes and previews the image directly.
