Summary: Most picture and movie files are already compressed, which means that they won't save space if made into a ZIP file.
ZIP is a very popular compression algorithm supported by many popular programs such as WinZip and PKZip, and recent versions of Microsoft Windows. ZIPping can often reduce the size of many files significantly. Note, though that I said "often". That doesn't mean "always". • Pictures in popular formats such as .jpg or .gif are already compressed. As are .mp3 audio files. As are all popular movie formats. Depending on the type of compression being used, compressing an already-compressed file at best does very little, and at worst makes the file bigger. So there's typically no advantage to ZIPping a photo, a movie, or an MP3. The one time it can be handy to ZIP compressed files is if you want to take several files (for example several pictures) and combine them into a single file for a single download. People still need to unZIP before they can see them, but it can be simpler to download one file rather than several. • Recent Comments
hello, how do i send folders of large JPGs from my home computer to my school's yearbook computer? i'm a photographer for them and i'm worried about compression or any degradation of quality. can i zip them or does that ruin quality? should i just put images onto a CD? thanks Posted by: shawn at November 15, 2005 07:52 AMZipping will not affect quality. It just won't make them any smaller. Depending on how big things are, you may be better off with a CD, yes. Posted by: Leo A. Notenboom at November 15, 2005 12:24 PMI have been trying to send mp3 files to the guys in my band but they never actually leave my computer. What's up? Posted by: Tami at December 1, 2005 03:35 AMHard to say without more details. It's possible that your email provider has a limit on how big an email can be, and the mp3's as attachments excede that size. Posted by: Leo at December 7, 2005 10:56 PMHi there, I'm going to be buying a new pc soon, is there any way of putting my mp3 files onto a cd so that i can just burn them onto the new hard drive instead of downloading them all again? Posted by: Neil at February 27, 2006 08:55 AMIf you have a CD burner you can burn them to CD like any other file(s). Perhaps I'm missing the point of your question. Posted by: Leo at February 27, 2006 06:23 PMhow do i save my pictures from my computer to a cd or a dvd? for back up in case comp/crashes or breaks. what do i do zip or what?? thanx. Posted by: mariam at August 27, 2006 05:15 PMI am a mac user. I send zip files daily to my office with multiple photos. Lately they have been telling me that they can not see all of they files that are in the folder I am sending. It works perfectly to everyone else I send it to except on their computer. Anyone else had this issue? just something that might make it easier for all. you can creat a self extracting file (EXE, application) for any type of file simply hit Start__>run__>type in "iexpress.exe" and follow along the instruction from their. i think its on most windows machines.
