Base64 Decoder
Decode Base64 encoded strings back to plain text or UTF-8 data.
How to Decode Base64
Three steps to translate ASCII radix-64 representations into human-readable strings.
Paste Base64 String
Enter raw encoded string or data URI payload into the input panel. The engine strips padding and invalid spacing automatically.
Select Character Set
Ensure UTF-8 or ASCII decoding is applied. URL-safe Base64 tokens with dashes and underscores are handled seamlessly.
Copy Decoded Output
Instantly copy decoded human-readable text to clipboard or export directly as a cleanly formatted .txt document.

Decode Base 64 text
Paste a Base 64 string and decode it. The output is treated as text rather than executed.
Example
aGVsbG 8= decodes to hello.
Before you use the result
Binary files may not be readable as UTF-8 text. Base 64 encoding is not a privacy protection.
