Encode & Decode
Base64 Encoder & Decoder — Text to Base64, Instantly
Base64 turns binary data and text into a safe ASCII string used in data URIs, API tokens, config files, and email attachments. This free Base64 encoder converts your text in one click — and decodes Base64 back to readable text just as fast.
Everything happens locally in your browser, so tokens and secrets you paste are never sent anywhere. A one-click copy button moves the result straight to your clipboard.

Frequently Asked Questions
What is Base64 encoding used for?
Base64 represents binary or text data as plain ASCII characters, commonly used in data URIs, email attachments, JSON web tokens, and API credentials.
Is Base64 the same as encryption?
No. Base64 is an encoding, not encryption — anyone can decode it. Never treat Base64 as a way to hide secrets.
Can I decode a Base64 string with this tool?
Yes. Switch to the decoder, paste the Base64 string, and the original text appears instantly.
Is my pasted text sent to a server?
No. All encoding and decoding happens locally in your browser.
