Node.js: how to remove EXIF data from images

In this article, we'll look at how to delete this data using Node.js, a widely used server-side JavaScript execution environment.

Deleting EXIF (Exchangeable Image File Format) data from images is an important practice to protect the privacy and security of your personal information. EXIF data can include details such as geographic location, the date and time a photo was taken, camera model, and shooting settings. In this article, we'll look at how to delete this data using Node.js, a widely used server-side JavaScript execution environment.

To work with images and remove EXIF data, we will use the exiftool-vendored package. This package provides a Node.js interface for exiftool, a powerful tool for reading, writing, and editing metadata in a wide range of files. Install the package by running:


npm install exiftool-vendored

After you've set up your environment and installed the necessary dependencies, it's time to write the code to remove EXIF data from images.:


const { exiftool } = require('exiftool-vendored')

async function removeExif(filePath) {
   try {
     // Write image metadata without EXIF data
     await exiftool.write(filePath, { all: '' }, ['overwrite_original']);
   } catch (error) {
     console.error(error);
   } finally {
     // Close the exiftool instance to avoid leaving processes open
     await exiftool.end();
   }
}

This code imports exiftool from the exiftool-vendored package, defines an asynchronous removeExif function that takes a file path as an argument, and uses < code>exiftool to remove all EXIF metadata from the specified image.

Conclusion

Removing EXIF data from images before sharing them online is an important step in protecting your privacy. Using Node.js and the exiftool-vendored package, you can easily automate this process for your applications or personal image management. Remember to always test your code with several images to ensure that the EXIF data is removed correctly.
