Create an animated jpg or jpeg

I looked into creating an animated jpg or jpeg file and found that it is actually quite simple to do.  Using a program called unfreez, which can be downloaded at, one can create an animated gif file.  Now, to create an animated jpg or jpeg file one has to change the file extension.  Therefore, if one is going to name their file kubrickheader, one will have to save it as “kubrickheader.jpg” or “kubrickheader.jpeg” with the double quotes.  If the quotes are not on both sides of the filename, the file will be named kubrickheader.jpg.gif.

For those that want to make Windows XP, Vista, or 7 show the hidden extension of a file for easy editing.  One can follow the instructions at  With that, one can easily rename the file kubrickheader.gif to kubrickheader.jpg without the fuss.

Unfortunately, animated jpg or jpeg files can be rendered by Internet browsers only.  Viewing an image using a photo viewing tool will not work.

NOTE:  There are probably many free programs available, such as GIMP, that can create animated gif files, but unfreez seems to be the simplest to use.  Unfreez takes 2 or more non-moving gif files and creates an animated gif file.  Therefore, all one needs is 2 or more non-moving gif files to add together.

An example can be seen by looking at the water at either or the header above.  My blog, which is using WordPress 2.9, has an animated gif renamed to a jpg file for the header.  Therefore, it is possible.

For those wanting to create a jpg or jpeg that looks animated using Javascript, the following will help.


Is this really an animated jpg or jpeg file?

No, this file is an animated gif file with an extension of jpg.  It seems that Firefox, Internet Explorer, and possibly others ignore the file extension and renders the image the way it is supposed to be.  In the case above, as an animated gif file.

NOTE:  Internet Explorer seems to have some problems rendering the animated jpg or jpeg file.  Opening an animated jpg or jpeg file stored on a harddrive will not work, one will have to view the animated jpg or jpeg on a website and/or a webpage.  Firefox does not seem to have this problem.  As for other browsers, I have not tested them yet.

As for making gif files that are comparable in quality to jpg or jpeg, GIMP for Linux, Windows, Mac OS or for Windows are very good solutions.  I find the quality of the saved gif from these programs are better than MS Paint.

For those wanting to convert AKA rename an existing animated gif to an animated jpg or jpeg file using other methods, go to

Create animated jpg or jpeg using tricks

As for jpg or jpeg that seem to be moving.  Do a Google search for optical illusions or visit  It seems that the eyes can play tricks when it comes to pictures that can make you dizzy.  I downloaded an optical illusion in jpg format that was moving, but I found out that it was just my eyes playing tricks on me.  The jpg picture was not moving at all.  Doing a Google images search for flowing leaves jpg will show a jpg that moves.  It even moves when printed on paper.

  1. There’s a proposed standard for animated JPEGs now! An AJPEG files is a number of JPEGs concatenated together, just like Motion-JPEG (mjpeg). Then, animation properties like loop option, frame-rate, etc. are added to the file via a JFIF compatible marker extension – so that image viewers / players implementing this proposed standard can play back animated jpegs just like animated gifs.

  2. Hi

    I just found, that ACDSee Pro 4, ACDSee Pro 5 and ACDSee 14 are able to show animated JPG’s. Older and newer version might well be able to do the trick, but I have them not installed for tests.

  3. Actually I have read the much talked about topic that you linked to and it may be that some countries are able to upload gifs but all of the animated pics on the link I provided at Rafik Houmrani fb page whose pics are viewable by the public have a .jpg extension so the gif slips through… but he ain’t sharing how he does it and makes a lot of gif lovers envious… This isn’t through an app so I don’t think he is using the fb tools you suggested..

    Thanks anyway David… I’ll keep digging… LOL

  4. From what I can see, talks about the animated gifs. It seems that there is much talk about it. I looked at page 5, and that is where the reasons can be found. First off, it seems that some countries are still allowed to do it (sounds ridiculous, but it is mentioned on the Facebook forum), but the animations are being phased out. Second, it seems that Facebook is slowly removing the ability to create animated files.

    The magic date seems to be May 14, 2010.

    As for the animations that are still working, provides the tools. Unfortunately, I am sure that many will find this method too much work to actually do.

    Hopefully, I have answered your question Paul.

  5. Hi… I have come across these animated jpgs on facebook examples here…!/album.php?aid=7893&id=100000876512176&ref=pb

    but when I try just renaming a gif it won’t allow the quotes in the file extension… so I opened my gif construction set uploaded the gif and the save as “giraffe.jpg” as you said but it saved as an unanimated jpg. I thought maybe it was as you said that it cannot be opened on a hard drive so I uploaded it to Facebook… but it was a still pic there. I am interested in how these few facebookers seem to get around it… Maybe I missed something. Any help appreciated… Thanks
