What is the Text to Base64?
The Text to Base64 tool converts your text into standard Base64 encoding. It first encodes the text as UTF-8, then applies Base64 so the result is safe for URLs, JSON payloads, email attachments and HTTP headers.
Base64 is a widely used data transport format. Every browser, backend and mobile platform understands it out of the box.
Who is the Text to Base64 for?
Developers embedding data in URLs or JSON, testers preparing HTTP payloads, security engineers analysing tokens, and anyone who needs to move text through channels that don't tolerate special characters.
Why use the Text to Base64?
- Handles Unicode via UTF-8 correctly.
- Live preview as you type.
- No character limit for practical inputs.
- Reversible - use Base64 to Text to decode.
- Runs entirely in the browser.
When should I use the Text to Base64?
- Embedding text in a data URL.
- Encoding a JWT payload for inspection.
- Preparing a test HTTP Basic auth string.
- Passing multiline text through an environment variable.
- Sharing binary-ish text safely over email.
Is the Text to Base64 safe and private?
Yes. This tool runs entirely inside your browser - your text is never uploaded, stored on our servers or shared with third parties. You can even disconnect from the internet after the page loads and it will keep working. That makes it safe for confidential notes, drafts, private messages and unpublished work.
How do I get the best results from the Text to Base64?
- Base64 output is about 33% larger than the input.
- Never use Base64 as a security measure - it is trivially decoded.
- For URLs, use URL-safe variants if your framework requires them.
- Verify the round-trip with Base64 to Text before shipping.
Frequently asked questions
What is Base64?
Base64 is an encoding that represents binary data using 64 printable characters, making it safe to embed in URLs, JSON, email and HTTP headers.
Is Base64 the same as encryption?
No. Base64 is encoding, not encryption. Anyone can decode it - do not use it to hide sensitive information.
Does it support Unicode?
Yes. Input is UTF-8 encoded before Base64 is applied, so emoji and non-Latin scripts work fine.
Is anything sent to a server?
No - encoding happens locally in your browser.
