About the Base64 to File

Base64 to File takes a data:...base64, string or a raw Base64 blob, decodes it in your browser and presents a download button for the resulting file — detected MIME and all.

How to use

  1. Paste the Base64 content (with or without the data: prefix).
  2. Optionally set a filename.
  3. Click Decode & download.

Benefits & key features

  • Supports any file type — images, PDFs, Office documents, JSON.
  • Automatically picks a sensible extension from the MIME type.
  • 100% offline; safe for decoded binaries containing proprietary data.
  • Pairs with Image to Base64 for full round-tripping.

Pro tip

If the download is garbage when opened, you likely pasted an incomplete Base64 string. Verify the final characters — Base64 ends in zero, one or two = signs.
