Decode Base64-encoded JavaScript back into runnable source code so you can review or audit it.
Inspecting payloads from analysis tools, pulling scripts out of data: URLs, or auditing dynamic-import strings.
Working with source files? Pair this with CSS Beautifier or use HTML to Base64 for markup-specific payloads.
Does the decoder evaluate the result?
