How to Compress Picture Files in a Computer

Most email accounts and online applications only allow you to upload and attach a file that is up to a couple of megabytes (MBs) in size. So when you have a group of large picture files that you need to send, or you just want to save space on your hard drive, you need to compress them. Most computers come with a built-in file zip program (like WinZip) that combines and compresses everything. You can also download a zip program, like StuffIt, to get a better handle on your large picture files.

Step

Save your picture files at a reasonable resolution in your image editing software—300 dpi is good. If possible, save them as JPEG files, since JPEGs tend to be lower in size as compared to TIFs. Ideally, your picture files should be no more than 5 to 10 MBs each if you're trying to save space.

Step

Create a new folder and move the picture files there so that they won't get mixed up with your other files when going through the compression process.

Step

Select all of the picture files that you want to compress. Either hold down the "Ctrl" key as you select each file individually, or click, hold down and drag your mouse over the files to select them.

Step

Right-click one of the selected files (even though you are right-clicking only one of the files, all of the rest should still be selected) and press "Send to>Compressed Folder" in Windows; and on a Mac click "Create Archive."

Step

Allow the files to compress into one zip file. This could take a few minutes, depending on the number of files and their size.

Step

Rename the compressed file to something that will help you identify it in the future; for example, "Halloween Party Pictures." Delete the unzipped picture files if you wish to save space on your hard drive.
