I want to convert Base64String extracted from file(ex: \"AAAAA....~\") to a javascript file object.

The javascript file object what I mean is like this code:

<

Answer 1

const url = 'data:image/png;base6....';
fetch(url)
  .then(res => res.blob())
  .then(blob => {
    const file = new File([blob], "File name",{ type: "image/png" })
  })

Base64 String -> Blob -> File.
