| | Do .jpg images lose quality with age?
Its just that i opened a couple of old (about 2 years) .jpg photos i had on my hard drive and noticed that the picture quality wasnt as good as i remember it being. There was artifacts and noise on them.
Windows Forums • View topic - Prize: Better JPEG - Edit JPEG photos ::
JPEG format is lossy, which means quality is lost when you save them. best compression on JPEGs to save you space without compromising picture quality.

User talk:Dr. Memory - UESPWiki::
May be it is possible to convert them to GIF or PNG withou loosing quality. to another format and not lose quality, but the JPEGs are already quite small.

Im i going mad or do they degrade with age?
no file format degrades with age but JPEG is a "lossy" format to everytime you "save as" .jpg you are losing more data as it compresses the file.
Acrobat User Community Forums / saving a pdf as a jpg::
well documented problem with Jpegs, they lose quality with each successive save. I only saved it once as a jpg, so it shouldnt have lost too much quality.

I suspect that you have developed a better eye over the last 2 years for the kinds of artifacts that jpeg compression leaves behind.
