Base64 file converter

Encode any file to Base64 text or decode Base64 text back into a downloadable file.

Any file type, up to 8 MB. The Base64 text will be about a third larger than the file.

Files and text stay in this browser.

How to use

  1. Choose encode or decode.
  2. Pick a file or paste Base64 text.
  3. Convert, then copy or download the result.

What it supports

Encode files up to 8 MiB; decode Base64 up to about 12 million characters. Decoded file type is detected from the bytes for a suggested name. Unlike the text-only Base64 tool, this works on binary files.
