Frequently Asked Questions
How do I convert a string to Base64 online?+
Paste your string into the input box above and click Encode. The Base64 encoded output appears instantly. You can then copy it with one click. No login or software needed.
What is Base64 encoding used for?+
Base64 is used to safely transmit binary data as text. Common uses include: HTTP Basic Authentication headers (username:password encoded), embedding images in HTML or CSS as data URIs, encoding data in JWT tokens, and safely passing data in URLs or JSON payloads.
How do I convert a file to Base64 online?+
For text files, copy the file contents and paste them here. For binary files like images, use our Image to Base64 tool which handles the binary encoding correctly.
How do I decode a Base64 string back to text?+
Paste the Base64 string into the input field and click 'Decode'. The original plain text is restored instantly. This works for any valid Base64 encoded string.
Does it support UTF-8 and special characters?+
Yes. The encoder uses UTF-8 encoding before Base64 conversion, so it correctly handles all Unicode characters including Hindi, Chinese, Arabic, emojis, and special symbols.
Can I encode JSON to Base64?+
Yes. Paste your JSON object directly into the encoder. This is commonly needed for API authentication headers, JWT payloads, and passing structured data in URLs.
Is Base64 encoding the same as encryption?+
No. Base64 is encoding, not encryption. Anyone can decode a Base64 string back to plain text. Do not use Base64 to protect sensitive data — use proper encryption (AES, RSA) for security.
