Hi,

> What makes it bigger? Base64 encoding?

In one word: yes.

In a few more words: Base64 takes 3 bytes of binary data and encodes them into 4 ASCII characters. This makes 32 bits out of 24 bits or for a size increase of roughly 33 percent. Your example (32 MB x 1.33 = 42ish MB) fits perfectly with Base64 overhead.

Cheers
Stephan
