Is the hex to base64 converter private?
Yes. Whitespace is ignored, but each byte must contain exactly two hexadecimal characters. All processing happens locally in your browser — nothing is uploaded to our servers.

Built for hexadecimal bytes
Whitespace is ignored, but each byte must contain exactly two hexadecimal characters.
No registration, watermark, queue, or server upload is required.
Use Base64 wisely
Base64 is ideal for text-only APIs, small embedded assets, test fixtures, and portable documents. It increases payload size, so external files are usually better for large public assets.
Frequently asked questions
What hex formats are accepted?
Continuous or space-separated hex pairs. Each byte must be exactly two hexadecimal characters.
Is the output standard Base64?
Yes, with standard alphabet and padding suitable for APIs and decoders expecting regular Base64.
When should I use Base64 for hexadecimal bytes?
Use it when a text-only channel or API must carry binary data, or when a small hexadecimal bytes asset needs to live inside a self-contained document. Prefer separate files for large, cacheable public assets.
