Convert Base64 to Text Online
Base64 encoding is widely used to represent binary data as ASCII text, commonly seen in API responses, data URIs, and email headers. When you receive a Base64-encoded string and need to read its original content, you need a reliable decoder that handles character encoding correctly. This tool decodes Base64-encoded strings back to their original readable text form, supporting standard and URL-safe Base64 variants and handling UTF-8 characters correctly. Paste your Base64 string and get the decoded text instantly — no server processing, everything runs in your browser. This is especially useful for developers inspecting JWT payloads, reading encoded configuration values, or decoding Base64 data embedded in API responses. The decoder shows clear error messages if the input is not valid Base64, helping you diagnose encoding issues quickly.
FAQ
- What is Base64 to text conversion?
- Base64 to text conversion decodes a Base64-encoded string back to its original text representation. Each group of 4 Base64 characters becomes 3 bytes of the original data, which are then interpreted as UTF-8 text.
- When would I need to decode Base64?
- Common use cases include reading API response bodies, decoding JWT token payloads, extracting embedded data from HTML data URIs, reading encoded configuration values, and inspecting email content.
- Can this decode Base64-encoded binary files?
- This tool decodes to text. For binary files like images encoded as Base64, use a dedicated Base64 to image converter that writes the correct binary output.
