I have an image that I reduced to 640 x 480 pixels as requested by my friend, but it also needs to be no less than 100k. The smallest I can get it down to in FastStone Photo resizer in 150K.
How do I get it to 100k?

Nevermind :rolleyes:
I changed the color depth from 24 bit to 8 bit, that did it. :smack:
Did you notice a big loss in quality by doing that?
If so, for future reference, you can also try:
It really doesn’t look all that much worse.
It’s a photo for an ID badge - It’s gonna look like crap anyway. Thanks for the suggestion!
Based on the fact that you were able to lower the quality at all, it wasn’t a JPEG to begin with. As a general rule, use JPEGs for photographs.
Replace quality with bit-depth. JPEGs, as far as I know, don’t have an 8-bit mode, except in black-and-white.
It’s JPG - don’t know if that’s significantly different than JPEG
Is it a color photograph?
If so jpeg is your best bet.
You can open the image in faststone by doubleclicking on it and save as by clicking on the disk in the bottom left corner.
If you select jpeg you can go to options to fine tune the compression.
As a starting point I would use the settings:
YCbCr colorspace
Progressive on
OptimizeHuffman on
From there you can adjust the quality vs size with the quality slider and by changing the color subsampling. You can preview how the image looks and the resulting file size as you play with the compression settings.
JPG is a commonly used file extension (or abbreviation) for JPEG files, so it’s probably the same thing.
100kB seems large for a 640x480 JPG image. What software did you use to reduce the image size? Most software allow you to adjust the JPEG compression rate (high compression = small image size and poor image quality), and you should be able to use much higher compression without any noticeable loss of image quality.
If the file is being used just for transfer, and can get decompressed at the other end, you should look at ‘KGB Compression’, it can get a file of ~1GB down to a ~10MB, and more if you’re willing to suffer some quality loss
I really like this.
More specifically, jpg is the old extension left over from the DOS days when filenames could only be up to 8 characters long followed by up to three characters for an extension. jpeg obviously was too long, so jpg was used. Then Windows eventually did away with the limitations and now you can use jpg or jpeg. The files themselves are exactly the same thing.
