How to use Base64 Decoder
Base64 Decoder. Decode Base64 to text or a file. The data is probably binary (an image, PDF or compressed file) rather than text.
The short answer
To decode Base64, paste the string: standard and URL-safe Base64 are accepted, missing padding is fixed, and the result is shown as UTF-8 text, or offered as a file download when it is binary data such as an image or PDF.
It runs in your browser. What you enter is not uploaded.

Limits worth knowing
Why does the decoded text look garbled? The data is probably binary (an image, PDF or compressed file) rather than text. Download it as a file instead.
Do I need the = padding? No. Missing padding is added automatically.
