npm install exif-remover

Example:

import fs from "fs";

const readStream = fs.createReadStream("sample.jpg");
const writeStream = fs.createWriteStream("sample-clean.jpg");

readStream
  .pipe(createStripMetadataTransform())
  .pipe(writeStream)
  .on("finish", () => console.log("Done!"));

import fs from "fs";
