How to strip type from Javascript FileReader base64 string?

by

The following functions will achieve your desired result:

var base64result = reader.result.split(',')[1];

This splits the string into an array of strings with the first item (index 0) containing data:image/png;base64 and the second item (index 1) containing the base64 encoded data.

Another solution is to find the index of the comma and then simply cut off everything before and including the comma: 

var base64result = reader.result.substr(reader.result.indexOf(',') + 1);

See JSFiddle.
