How to use this tool
- Paste plain text and choose Encode, or paste a Base64 string and choose Decode.
- Click Run conversion to process the value locally.
- Copy the output or swap it back into the input for another round.
What you can use Base64 Encoder/Decoder for
Encode text to Base64 or decode Base64 back to readable Unicode text directly in your browser.
- Encoding short config values or test strings
- Decoding Base64 snippets from API examples
- Checking whether a payload is valid Base64
- Working with Unicode text without leaving the browser
Example workflows
| Text to Base64 | DailyWebTools becomes RGFpbHlXZWJUb29scw==. |
|---|---|
| Base64 to text | Decode a copied token-like sample to inspect non-secret test data. |
| Unicode text | Use UTF-8 handling for emoji and non-English text. |
Base64 quick reference
| Encoding | Turns readable text into Base64 text that is safe to copy through systems that expect plain characters. |
|---|---|
| Decoding | Turns Base64 back into readable UTF-8 text when the content is text-based. |
| Padding | Some Base64 strings end with = or == characters so the encoded length lines up correctly. |
| Security | Base64 is reversible encoding, not encryption, hashing, or password protection. |
When Base64 output looks strange
The decoded data may be binary, compressed, encrypted, or not valid UTF-8 text. If the result is unreadable, the input may not be text content even though the Base64 string itself is valid.
Safe Base64 workflow
Use Base64 for safe test strings, documentation examples, or text snippets that need to pass through plain-text systems. Do not treat a Base64 value as hidden. Anyone can decode it, so never rely on Base64 to protect passwords, private keys, access tokens, or customer data.
If a decoded value is unreadable, it may be binary or compressed data rather than normal text. In that case, do not assume the conversion failed.
Privacy and accuracy notes
This tool is built for fast everyday work in a browser. Review results before using them in production systems, financial decisions, legal documents, or other high-stakes workflows.
- Base64 is encoding, not encryption.
- Do not paste real passwords, private keys, or production tokens into any tool on shared computers.
- Decoded binary data may not display as readable text.
Best practices for dependable results
Use clean input, review error messages, test important outputs in the destination app, and keep original files or text when the work matters. DailyWebTools keeps each tool page focused on one clear job so the result is easier to understand, repeat, and compare with related utilities.
FAQ
Is Base64 secure encryption?
No. Base64 is a reversible encoding format, not encryption or hashing.
Does this support Unicode text?
Yes. The tool uses UTF-8 encoding and decoding for browser text.
Why does decoding fail?
The input may contain invalid Base64 characters, missing padding, or binary data that is not valid UTF-8 text.
Is my input uploaded?
No. The conversion runs in the browser.
