How does one reduce the file size of an image to be used in an avatar?

Simply choose the file, open paint, click on re-size, and reduce it to the avatar size limit, 100 x 100 pixels. Then "save as", so you can keep the original, and have a separate file for the reduced one.

I have reduced an image to 4 pixels, and it's file size remains at 12.6 Kb file size and will not be allowed. How do I change the file size?

If it is something like a JPEG, then there is overhead (eg what is called the "EXIF data", including date and camera settings.

12.6 kbytes is way under the limit of 256k.

Control of file size depends on the format. For example, with JPEG, you select the quality which in turn affects how aggressive the compression is.

Oops---I missed the part about the avatar. I did not know there was a file size limit.

Post the picture and we can play with it.

My avatar is 100 X 100 and the file is 6.25 k. I typically use 80% quality for jpegs.

Here is the image. I reduced it to 100 pixels max, and deleted all possible file attributes.

I found a utility** to completely remove the "metadata" (including EXIF)

Here is your new file--now <5Kb

**I used a utility called "exiv2" on Linux. I am sure there are similar tools for other systems.
To make my avatar, i must have done something like this, but the aging brain can't remember.

Thank you both! I used the image Dave Doughty put up. Thank you Pixellany for your help also. I am going to look into each of the methods each of you used.

We both did the same thing, but with different hammers...

Mine removed ALL metadata---Dave's maybe only part of it?

I, too, have a picture that I'd like to use as an avatar. I reduced it to 100 x 83 pixels using Corel Photopaint and saved it as a copy for email. While that removed all of the metadata data, it apparently didn't remove the now empty metadata placeholders. The file is now 14KB in size. What method can I use to remove all of the EDIF information if I'm running Win7? I'd rather not clutter up my machine with another program to do this as creating an acceptable avatar is the only use I'd have for it.

On second thought, why not just have a 100 x 100 pixel size limit, forget the file size limit and let it go at that? Yeah, yeah, I know "that stuff takes up space" and we must conserve space. C'mon, it's not the days of the 4K machine anymore which wouldn't even hold my measly avatar!

I was all set to download Irfanview to allow deleting of the file data, but my online security suite waved me off it and blocked it's download attempt. I don't like to go against it, as it has been a very good suite for years now.

Does Photopaint allow you to set a specific JPG compression ratio and file size? That's how I got 19&41's picture down to 6 kb. Irfanview has a menu that pops up when you hit Save As which allows this customization.

Dave,

No, it doesn't. I even bit the bullet and downloaded BatchPurifier which removes all EXIF and othe hidden metadata - no go. So what you see now is the only avatar I could create that would fit after running it through BatchPurifier. I think it says it all for me...

Put up the image you want to use, maybe someone could do it up for you, that has the utility to do it.

OK, I finally figured out how to set the jpeg compression amount to get the avatar I really wanted! I looked and looked through the Corel Help for PaintShop Pro X6 to no avail. A Google search turned up an actual Corel page that explained how to do it. Turns out it's buried in the Options for the Save As command. Anyway, thanks to those who took the time to reply and offered help. I hope that some day soon I'll be able to return the favor.

John

Ok, i read through this thread and the FAQs and i don't see anything on it. I'm trying to post a pic in a pm and it says "The extension jpg is not allowed." So i changed it to a bmp and it says "The extension bmp is not allowed." Probably something simple i'm missing.

Doesn't work in a PM. Don't know why.

I use the IMG codes included with links to Photobucket (free hosting site) to have my pictures appear in a PM. It's a quick and easy workaround.
