Use this Base64 encoder and decoder when docs, local tests, examples, fixtures, support notes, or small developer workflows 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.
Base64 decodingDecode short Base64 strings to inspect safe sample values or support examples.
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, Base64 text, or a URL-safe Base64 sample.
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.
Base64 is treated as reversible encoding, not encryption.
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 encode plain text to Base64?
Yes. Choose Encode and paste the plain text you want converted.
Can it decode Base64 text?
Yes. Choose Decode and paste the Base64 value, including URL-safe Base64 samples that use hyphens or underscores.
Should I paste secrets here?
No. Avoid using private keys, passwords, or access tokens in online tools.
