Base64 Decode
Paste Base64 and see the decoded text live — whitespace and line breaks are stripped automatically, URL-safe Base64 variants are accepted, and invalid input shows a clear error instead of garbage.

Frequently asked questions
Is my text sent anywhere?
No. The transformation happens in your browser with plain JavaScript — nothing you type or paste leaves your device.
Does it accept URL-safe Base64?
Yes — both standard (+, /) and URL-safe (-, _) alphabets decode, with or without trailing = padding.
