Quite often, users cannot decode Base64, because they got a malformed or invalid string. For example, this can happen if the source outputs an unexpected Base64 standard, the user copied unnecessary data, or something damaged the Base64 value. As a rule, such strings cannot be decoded without additional processing or human intervention, and because of this some inexperienced users mistakenly think that these strings are not decodable. Therefore, to help you decoding the undecodable, I developed a “repair tool” powered by some kind of magic, which is able to fix malformed Base64 and even inform you about detected errors. Of course, don’t wait for miracle, but don’t be surprised if it happens.
Please note that the repair tool may return many false positives and you should manually tidy up the results. If you get some weird results, please don’t judge me harshly. This tool can repair hundreds formats of poorly formatted Base64 values and in some cases it’s necessary to sacrifice accuracy in order to achieve good results. If you got wrong results, please send me your string and I’ll try to improve this tool.
