What is the Base64 to Text Tool?#
The Base64 to Text Tool decodes a base64 string back into plain text. Paste the string and the decoded text appears as you type, ready to copy.
Base64 strings are often produced when text is moved through configuration files, URLs, or systems that cannot handle special characters directly. This tool turns them back into readable text.
How to Use#
- Paste the base64 string you want to decode.
- Check the decoded text in the output.
Standard and URL-safe Base64#
- Standard base64: uses
A–Z,a–z,0–9, plus+,/, and=padding. - URL-safe base64: replaces
+and/with-and_, and usually has no=padding.
Both forms are detected automatically, so you can paste the string as-is.
Common Use Cases#
- Restore a value that was encoded before being pasted into a JSON or YAML configuration file.
- Read the content of a string embedded in a URL or query parameter.
- Inspect base64 test data while checking an API or a decoder.
- Recover text that an older system stored in base64.
Frequently Asked Questions#
No. Everything runs in your browser, and your data is not uploaded anywhere.
No. Base64 is an encoding, and anyone can decode it. Do not use it to protect passwords or other sensitive data.
Yes. URL-safe base64 is detected automatically, so you can paste it as-is.
The input is not valid base64, or the decoded data is not text. Check the input for missing or extra characters, and paste base64 that contains text.
Notes#
- Only base64 that represents text can be decoded. Data such as images or files is not text, so the decoded result is rejected.
- Very long strings are processed in the browser's memory. Extremely large inputs may take time to decode.
