A PWA app to view all EXIF data of your .jpeg or even .heic files!

Hi everyone!

In this post, I will introduce you my new created website, EXIF Viewer, it's a PWA app to let you view all EXIF data of your .jpeg or even .heic image files.

What is EXIF

EXIF i.e. Exchangeable image file format, is a standard that specifies the formats for images, sound, and ancillary tags used by digital cameras (including smartphones), scanners and other systems handling image and sound files recorded by digital cameras.

It will include some informations when your camera take photos:

  • Make, like: Apple for iOS
  • Model, like: iPhone 8
  • GPS*, will include the latitude and longitude
  • Date time, like: 2020:06:25

etc.

Why to build this website

Privacy is becoming more and more important in our daily life, as we see in above, an image may(or may not) include many EXIF data that may expose your mobile model, your GPS location etc.

One can know from an image that WHEN the time you use WHAT camera(mobile) at WHERE location took this image.

It's not good for privacy.

How to use this website

It's simple enough and I just put 2 screenshots in here and sure you will know.

Before you select an image

After you select an image

Easy, right?

What's next

In the next few releases, I will provide the EXIF data striping so you can download the image with no EXIF data, for privacy.

Another words

  1. The website will not upload your image to anywhere, it's just in your computer and in your browser

  2. Not all the images include EXIF data and even an image does, it may not include all the EXIF data, that's another reason you will need this website.

  3. It's on GitHub.
