Is the base64 to hex converter private?
Yes. Hex output is larger than Base64 but easier to compare byte-by-byte in logs and protocol documentation. All processing happens locally in your browser — nothing is uploaded to our servers.

Built for Base64 binary data
Hex output is larger than Base64 but easier to compare byte-by-byte in logs and protocol documentation.
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 case is the hex output?
Lowercase hexadecimal pairs with no separators, suitable for logs and byte-by-byte comparison.
When is hex output more useful than Base64?
Debugging binary protocols, comparing hashes, and reading raw byte values in documentation or security reviews.
When should I use Base64 for Base64 binary data?
Use it when a text-only channel or API must carry binary data, or when a small Base64 binary data asset needs to live inside a self-contained document. Prefer separate files for large, cacheable public assets.
