Part 2. Compress ISO file Free with DVDShrink<\/strong><\/h2>\n
DVD Shrink is a freeware DVD transcoder program for Microsoft Windows that uses a DVD ripper to back up DVD video. DVD Shrink's purpose is, as its name implies, to reduce the amount of data stored on a DVD with minimal loss of quality, although some loss of quality is inevitable (due to the lossy MPEG-2 compression algorithm). It creates a copy of a DVD, during which the coding only allowing the DVD to be played in certain geographical areas is removed, and copy protection may also be circumvented. A stamped DVD may require more space than is available on a writeable DVD, unless shrunk. Many commercially released video DVDs are dual layer (8.5 GB); DVD Shrink can make a shrunk copy which will fit on a single-layer (4.7 GB) writeable DVD, processing the video with some loss of quality and allowing the user to discard unwanted content such as foreign-language soundtracks. <\/p>\n
<\/a><\/div>\nYou could follow the below steps to learn how to compress ISO file with DVD Shrink to smaller size.\n <\/p>\n
\n- \n
- Download and install DVD Shrink on your computer. Make sure your source ISO image file is ready for compressing. <\/li>\n
- Kick off DVD Shrink on your computer and then click the “Open Files” button to browse and load source ISO file. <\/li>\n
- For ISO file compression, select “Automatic”. This will help compress ISO file to fit on DVDR disc or other devices. <\/li>\n
- Click “Backup” option. Then, select “ISO” from the drop down list. <\/li>\n
- Select a directory to save your ISO to, you can always move it later. <\/li>\n
- At last, click the “OK” button to start compressing ISO file within DVD Shrink. <\/li>\n<\/ol>\n<\/div>\n
