How to encode and decode Base64 text
Convert plain text to Base64, decode Base64 back to readable text, and catch common copy mistakes in developer and support workflows.

Base64 is a text representation for bytes. It is useful when a value needs to travel through JSON, email, environment variables, examples, or forms that expect plain characters. It is not encryption. Anyone can decode a Base64 string, so do not treat it as a safe way to hide passwords, tokens, private keys, or customer data.
Start with the direction you need
There are two common jobs. Encoding turns readable text such as ToolBento into a Base64 string. Decoding takes a Base64 string and tries to show the original readable text. If you are debugging an API example, webhook payload, or documentation snippet, first decide whether the value you copied is the original text or the encoded version.
What to enter in ToolBento
Open ToolBento's Base64 Encode/Decode tool and use the Text or Base64 field. Paste plain text when you want an encoded value, or paste a Base64 string when you want to decode it. Use the value itself rather than a full JSON object, surrounding quotes, labels, or comments unless those characters are intentionally part of the text you want to encode.
Press Encode / Decode for both views
After the input looks right, press Encode / Decode. The result shows an Encoded section with the Base64 version of the current input. It also shows Decoded if input is Base64, which returns readable text when the input is valid Base64 or Not valid Base64 when it cannot be decoded.
Check whitespace before comparing results
Base64 output can change if the original text includes a trailing space, line break, tab, or different capitalization. When two systems produce different strings, compare the exact input first. Copying from a terminal, spreadsheet, chat message, or CMS editor can add invisible characters that make a correct encoder look wrong.
Use decoded text as a clue
Decoding is helpful for checking examples, reading harmless test payloads, and finding whether a copied value contains the text you expected. It does not validate an authentication token, verify a signature, unzip compressed data, or prove the decoded content is safe. If the value controls access or money, use the decoded text only as a debugging clue and verify it in the system that owns the format.
Common Base64 mistakes
Do not confuse Base64 with URL encoding, Base32, hex, JWT decoding, or hashing. They solve different problems and produce different-looking output. Also watch for URL-safe Base64 values that use different characters in some token formats; if a value is really a JWT, a dedicated JWT decoder will usually be clearer than a generic Base64 text check.
