How to resize image without losing EXIF data?

How do you get rid of the EXIF data of an image?

  • Also, are there ways that people can track you down somehow just through an image online?

  • Answer:

    If the camera has a geotagging function (either a built-in or connected GPS receiver) and the picture in question was taken in or around your house, maybe. Otherwise, the Exif data is pretty harmless. All that's saved is usually the settings used to shoot (ISO, shutter speed, etc.), some technical things (resolution, PPI, etc.), date and time the picture was taken, and some other miscellaneous stuff like camera make and model. If your whereabouts are in question and you're clearly in a picture somewhere then it can be incriminating. The contents of the picture are another story. There are freeware Exif strippers available online. This one, for example, does exactly and only what you want: http://www.steelbytes.com/?mid=30 This program, Exif Tag Remover, is a little more comprehensive: http://www.rlvision.com/exif/about.asp Some programs like Photoshop strip the information upon resaving. Open the picture in such a program and save it as a seperate JPEG.* Follow-up: * Correction: Photoshop does not strip the Exif upon a normal "Save as" function as hlstarch brought up though it does when you "Save for web". Though all of which hlstarch said below is completely true, he or she also talks about the other metadata that is not always contained in the Exif (a standard for the information included by a camera) but saved post-Exif as a result of using post-processing applications. A file straight from the camera contains information that would be impractical for anyone trying to track another person down provided that no geotagging was used and that nothing identifiable was captured in the image itself.

The previous answer is generally correct, but there are a few things to note: - Exactly what's stored in exif data varies from camera to camera. There's a bunch of standard stuff, but the companies also include manufacturer's notes, which include whatever information the maker feel like including. In many cases, this includes an identification of the specific camera, by serial number or some other method. - Photoshop does not strip out all the exif data when you save a file under another name. It does (at least in my experience) strip out the manufacturer's notes, though. - A couple of other free programs for viewing and modifying exif information, if you're so inclined: PhotoMe is pretty nifty and easy to use. You can edit some, but not all, exif information: http://www.photome.de/ Exiftool is widely used, but it's a command-line application, which is may be too daunting an idea for those who never used a computer before Windows. It allows you to to do just about anything to exif data, including stripping it all out. Unfortunatly, the website where it has always been doesn't seem to be responding, but if you do a google search, you can find it. - I suppose exif data *might* help someone identify the source of a photograph, though it would take some work. If you have a camera serial number, that won't tell you much in the absence of a list of camera owners by serial number - which probably doesn't even exist and would likely not be obtainable if it did. You could do a massive search of online photos and identify others taken with same camera, then piece together information from the exif data and the photos themselves. The date and time information (if it's accurate), could help you identify the photographer, but only if you pieced it together with other information. - One bit of metadata that actually *has* caused people problems: JPEGs (and some other formats) include, in the file, not only the image data, but a small thumbnail image. Photoshop changes the thumbnail when you change the photo, but some editing applications don't. There have been instances in which people have cropped photos or altered them to hide things they didn't want seen ... but the thumbnail still had the old version. You can find news stories (some pretty amusing, some pretty R-rated) if you do an online search. - Your image-editing software may drop in notes of its own. This certainly might include your name, since software generally knows the registered owner's name, or maybe your username from the operating system. - Many people intentionally put additional information into exif data. This might include geotags (latitude and longitude) or something as straightforward as the photographer's name. I think that's pretty common for professional photographers, who *want* people to find out who took the photograph (and also may specifically include a copyright notice as well).
