Decode Base64 back to readable text or files, instantly and privately in your browser. Paste a Base64 string — standard or URL-safe, with or without padding, even with line breaks — and get the original text back, UTF-8 correct. Base64 decoding is the more common need (it’s how you read a value pulled from a JSON Web Token, a config file, an Authorization: Basic header or an email attachment), and this page opens straight in Decode mode. Nothing you paste is uploaded: the decode runs with your browser’s built-in atob, so secrets you decode — tokens, credentials, payloads — never leave your device. If the string turns out to be a file or image, switch to the file view to download or preview it.
