Free Text to Base64
Base64 turns any text into safe ASCII for transport and storage. Type or paste anything — including emoji and non-Latin scripts — and this free encoder produces valid Base64 instantly, with correct UTF-8 handling.
How to Use the Text to Base64
- Type or paste the text to encode.
- Click “Encode to Base64”.
- Check the output length.
- Copy or download the Base64 string.
Features
Unicode-safe encoding via UTF-8 bytes (not naive btoa), so emoji and CJK text encode correctly. Reports output length, and includes one-click copy plus .txt download. No server round-trip — encoding is instant even for large texts.
Benefits & Use Cases
Developers encode credentials and tokens for Authorization headers. API testers prepare Base64 payloads for requests. Learners see how encoding transforms text. Anyone embedding small text in data URIs gets valid output fast.
Tips
Base64 output is ~33% larger than the input — that is normal, not a bug. Standard Base64 includes + / and = padding; if your API needs URL-safe Base64, replace + with -, / with _ and strip = manually. Decode it back with the Base64 to Text tool to verify.
Frequently Asked Questions
Is the Base64 encoder free?
Yes, free and unlimited.
Does it support emoji and Unicode?
Yes — it encodes UTF-8 bytes, so all Unicode text works correctly.
Is Base64 encryption?
No. Base64 is encoding, not encryption — anyone can decode it. Never use it to “hide” secrets.
Why is the output longer?
Base64 represents 3 bytes as 4 characters, so output grows by about 33%.
Is my text uploaded?
No, encoding runs entirely in your browser.
