Show HN: I got tired of Base64, so I made a numeric-only alternative

3 Forgret 7 9/12/2025, 5:12:44 PM

I created numbase is an alternative to Base64 that encodes data into a single large number instead of ASCII characters. It's useful if you want to store or transmit data in numeric form and easily apply compression algorithms like Huffman.

Hmm - why would you do that? How much data, if any, can you safe by compressing it as to compared with the classic Base64?

Forgret · 5h ago

It depends on the data. Base64 adds ~33% overhead, while NUMBASE can be encoded into one large number at once and compressed with Huffman or other algorithms. For some data types this results in fewer extra characters.

I'm very curious as to how one gets tired of Base64?

Forgret · 5h ago

Base64 is great and widely used. I just wanted to experiment with a numeric-only representation. NUMBASE encodes everything into a single large number, which can make certain compression schemes like Huffman more efficient and opens up new ways to store or transmit data.

URL I added it to the description.
