EXIF Eraser – Free EXIF/IPTC/XMP erasing software

A long time ago, I was using Delphi to write all of my software. I think Delphi was and still is the best choice for rapidly developing Windows UI applications (though I have to admit, I have superficial familiarity with Visual Basic and C#, that I believe are also good candidates for Windows UI development). The biggest problem with Delphi, is that you have to write in Pascal, which is kind of an anachronistic language.

Anyway, a month ago, I decided It will be a nice thing, to have a look at Delphi again, and check what way it did along the years I left it. I downloaded the latest Delphi version from, which I believe is currently the company that maintains and develops the future of Delphi. Back then, Delphi was strongly identified with Borland. I was surprised to find, that things didn’t changed much along the years. Many features of modern IDEs were added, but the main idea was pretty much identical.

In order to refresh my Delphi development skills, I decided to write a small utility program, that wipes EXIF, IPTC and XMP meta data from image files. EXIF (Exchangeable Image File) data is a record of what camera settings were used to take a photograph. This data is recorded into the actual image file. Therefore each photograph has its own unique data. EXIF data stores information like camera model, exposure, aperture, ISO, what camera mode was used and whether or not a flash fired. IPTC and XMP are also additional meta data that are attached to image files.

I named the utility: Free EXIF Eraser. The nice thing is, that it deletes EXIF, IPTC and XMP meta data without doing any modifications to the original image. That means, the quality of the original image is kept untouched.

It was so fun and easy to get back to Delphi development, that I decided to put a bit more effort on my small utility: I dedicated for it a special domain and created a home page. If you need a small and lightweight utility, that will easily erase EXIF, IPTC and XMP meta data, you can check:
