Function overloading in this way is generally discouraged
(http://google-styleguide.googlecode.com/svn/trunk/cppguide.html#Function_Over...).
I would change the name to something like SerializeFormDataToString() and
DeserializeFormDataFromString().

I would also mention in the comments why this function is useful, in particular
that it's base64 encoded to remove embedded NULLs. Without any context I would
just assume that this coerces the Pickle into a string.

Nit: I would also add some whitespace in between these functions. Feels a little
cramped now.

Done, I've even added mention about base64 in functions names, this seems to be
more informative.

 // Deserialize FormData. This assumes that |iter| is currently pointing to
 // the part of a pickle created by SerializeFormData. Returns true on success.
 bool DeserializeFormData(PickleIterator* iter, FormData* form_data);
+// Deserialize FormData. Returns true on success.
+bool DeserializeFormData(const char* input, FormData* form_data);
