The one modern tool to decode Base64 data

Decode Base64 data

About is the one modern tool you need to decode Base64 data. This tool allows you to decode Base64 data into human-readable text. This website also serves as a one-stop resource for researching Base64, when you need to understand how Base64 works or provide evidence of particular Base64 behavior.

What is Base64?

Base64 is an encoding scheme used to carry text and other data. It is used for simple obfuscation or to ensure data integrity in environments which only reliably support text content, such as websites and other software. The number 64 comes from the 64 ASCII characters which can be used in encoded Base64 data.

How to use

Copy the Base64 data from the source, such as another website. Then paste into the blue text box above where it says "Paste Base64 data here". The decoded data will immediately appear below. Then, 🎉 celebrate!

If the data does not decode automatically, click/tap the "Decode" button. If an error message is shown, please re-copy the text from the source again carefully, from beginning to end, and re-paste into the blue text box above.
