Question 1

How do I decode Base64 to a file?

Accepted Answer

Paste your Base64 string into the input area, optionally select the MIME type (or use auto-detect), and click Decode. The tool will convert it and provide a download link.

Question 2

What file types are supported?

Accepted Answer

The tool supports all file types including PDF, ZIP, images (PNG, JPG, GIF, SVG, WebP), audio (MP3, WAV), video (MP4, WebM), documents and any binary data.

Question 3

Is my data safe?

Accepted Answer

Yes. All decoding happens entirely in your browser. No data is ever uploaded to any server.

Question 4

Does it work with data URI format?

Accepted Answer

Yes. The tool automatically detects and handles data URI format (data:mime/type;base64,...) including extracting the MIME type and file extension.
