Frequently asked questions
Why does my decoded text look like nonsense?
The data may not be text, for example an image or a file, or it may use a different character set. Check what the Base64 string was made from.
Can I use Base64 to hide a password?
No. It only changes the form of the data, and decoding takes a second. Use proper encryption or a password manager for secrets.
