Enable Image File Compression to Save Disk Space

Why compress an image file?

The more files that need to be backed up, the larger the image file storage space will be. Regular data backup may also require compression to reduce storage space, such as compressing a 20GB C drive to a 5GB image file.

Best free image file compression software for Windows

Qiling Disk Master offers a compression feature for image files, with three levels of compression: None, Normal, and High. The default compression level is set to Normal, allowing users to adjust the level according to their needs during the backup process.

• None: The software backs up images quickly, but uses more storage space, as it doesn't compress the files.
• Normal: It's the recommended compression level, offering a normal extent of compression that balances backup and restore speed with image file storage space, requiring neither too much time nor too much space.
• High: The new compression algorithm will significantly reduce the size of image files, but at the cost of longer compression times during backup and longer decompression times during restore.

Qiling Backup provides four backup options: System Backup, Disk Backup, Partition Backup, and File Backup, catering to various user needs. You can choose the appropriate backup type based on your preferences. Download and install it on your PC to get started.

How to compress a disk image file efficiently

Here come the operating steps.

1. Select a backup type to enter the setting page. Here I choose "Disk Backup" to create a disk image of my computer hard drive.

2. Select the source disk and destination path, which can include a local disk, external hard drive, USB thumb drive, network location, etc.

3. To compress a disk image, click on "Options", then select "Advanced" from the pop-up menu. Three compression levels will be displayed: None, Normal, and High. Choose a level and click "OK" to save the settings.

4. Click "Proceed" when you are ready.

The ideal compression rate depends on the type of files being backed up, with better compression rates achievable for text-based files like .txt, .doc, and .xls, but not for image or video files like .jpg, .mp3, and .avi.
