DATA / BASE64
Base64 encoder / decoder
Convert UTF-8 text or binary files without uploading them.
Encode up to 10 MB. Decode Base64 text/files up to 20 MB, producing at most 10 MB. Text uses UTF-8.
Decoding accepts line breaks, spaces, and omitted padding. Other invalid characters, mixed alphabets, and invalid padding are rejected. Paste only the Base64 payload, without a data URL prefix.
Enter text or choose a file. Base64 is an encoding, not encryption.
