It depends on the compression … that is, how much digital information is omitted from the original file to create a smaller digital file (the jpeg).
. To the casual eye, the degradation will probably not be observable. But when you magnify portions (such as to be able to read handwriting) the degradation becomes somewhat more apparent and problematic. Subsequently, if you copy the jpeg, the degradation increases each time you make a copy or a jpeg copy. Eventually, after a number of copies, details such as handwriting become more difficult to see. All of this occurs because each jpeg omits visual data from the previous file.

Isn't recommended that photo's in Legacy be in JPG format? Does just viewing them in Legacy, or any other app for that matter, degrade them? gc ---------- Original Message ---------- From: JLB <j...@jgen.ws> To: LegacyUserGroup@LegacyUsers.com Subject: Re: [LegacyUG] jpeg and pdf pictures Date: Fri, 18 Jan 2013 13:56:12 -0800 And no, you shouldn't be editing JPG's. It's a compressed format and every time you edit and re-save you'll lose picture quality. Your photos should be in TIFF to begin with but that's not always possible. ---- JL Beeken JLog - simple computer technology for genealogists http://jlog.jgen.ws/ Legacy User Group guidelines: http://www.LegacyFamilyTree.com/Etiquette.asp Archived messages after Nov. 21 2009: http://www.mail-archive.com/legacyusergroup@legacyusers.com/ Archived messages from old mail server - before Nov. 21 2009: http://www.mail-archive.com/legacyusergroup@legacyfamilytree.com/ Online technical support: http://www.LegacyFamilyTree.com/Help.asp Follow Legacy on Facebook (http://www.facebook.com/LegacyFamilyTree) and on our blog (http://news.LegacyFamilyTree.com).
