Base64 Tool#

Base64 Tool converts text or bytes to and from Base64.

Encode#

Enter text and select encode. The result is an encoding, not encryption.

Decode#

Paste a valid Base64 string and select decode. Binary output may not be readable as text.

Common mistakes#

• Missing padding
• URL-safe Base64 used as standard Base64
• Treating Base64 as secure storage
• Decoding untrusted binary content without checking its type

Privacy#

Processing is local. Base64 can still contain credentials, tokens, files, or personal data.

Example#

URL-safe Base64 may use - and _ instead of + and /. Padding rules also vary by protocol.
