Local Processing

Decoding happens entirely in your browser — the Base64 data is never uploaded to a server.

Accepted Input Formats

This tool accepts a full data URI (starting with data:image/png;base64,, which specifies the image format explicitly) or a bare Base64 string with no prefix, in which case it's assumed to be PNG data. Any whitespace or line breaks accidentally introduced when copying the string are stripped automatically before decoding.

Key Takeaways

Accepts Data URIs or Bare Base64: Automatically detects and handles either format.
Instant Preview: See the decoded image before downloading it.
Client-Side Only: All decoding happens locally in your browser — no data is ever sent to a server.
