Base64 Encoder

Use this Base64 encoder when docs, local tests, examples, fixtures, or small developer notes need text encoded to or decoded from Base64.

For

Developers, QA testers, technical writers, students, support teams, and operators handling small encoded text snippets.

Problem

Base64 strings are common in examples and test data, but manual encoding or decoding interrupts the workflow.

Output

A copyable Base64 encoded string or decoded text result.

Use when

Docs and examplesEncode small text snippets for API docs, tutorials, and example payloads.
Local testingCreate or inspect Base64 text for fixtures, demos, and lightweight tests.
Support debuggingDecode small Base64 values to understand what a pasted sample contains.

What to include

Paste text onlyUse small text snippets rather than private credentials, tokens, or sensitive production data.
Choose encode or decodeSelect the operation based on whether the input is plain text or already Base64.
Remember Base64 is not encryptionEncoded text can be decoded by anyone who has the string.

Steps

01Enter textPaste the plain text or Base64 string.
02Select operationChoose encode or decode and whether to include the original.
03Copy resultUse the output in docs, examples, or tests after reviewing the content.

Try this

Encode
Base64 encode sample text.

Useful for docs and fixtures.

Decode
Base64 decode c2FtcGxlIHRleHQ=.

Good for inspecting encoded samples.

Original
Base64 encode this text and include the original.

Works for review notes.

Good output

  • The operation matches the input type.
  • No secrets, tokens, or sensitive values are pasted into the tool.
  • Decoded content is reviewed before reuse.

Avoid

Treating Base64 as secureBase64 is encoding, not encryption, and should not be used to hide secrets.
Using incomplete encoded textTruncated Base64 strings may decode incorrectly or produce unusable output.

Limits

This tool transforms text only. It does not encrypt data, validate secrets, upload files, or store encoded values.
Avoid pasting private keys, passwords, access tokens, or sensitive production data into any online tool.

FAQ

Is Base64 encryption?

No. Base64 is reversible encoding and should not be used to protect secrets.

Can it decode Base64 text?

Yes. Choose Decode and paste the Base64 value.

Should I paste secrets here?

No. Avoid using private keys, passwords, or access tokens in online tools.
