Lossless compression ensures that the quality of the image remains untouched while viewing, transferring, uploading, printing, or editing it. For Creative Liberty: If the image represents your creative piece of work, a high-quality format needs to be ensured. Lossless compression works in such cases.Ħ. On the other hand, if your website represents your portfolio, presenting HD-quality images is a must. This will prevent your user from having an unpleasant viewing experience, where the images take too much time to load and cause the website to malfunction. If you want to ensure that your website loads completely and quickly, all your published images should be lossily compressed. For Publishing on Web: Choosing the compression type while publishing photos on the web depends upon your website’s main focus. It allows you to showcase the quality that your viewers are seeking.ĥ. On the other hand, if your uploaded images represent your creative work, lossless compression is recommended. Similarly, if you fill up e-forms requiring you to submit image files within a specified size limit, lossy compression would do the job. Your images would load more quickly for your friends and family to see. This will remove all the unnecessary data that might be slowing down the uploading/ loading time. For Uploading Online: If you are trying to upload your pictures to your social media handles, lossy compression would favor your case. Lossless compression would ensure that your image’s quality remains the same while transferring, but this would increase the transfer duration and file size.Ĥ. Lossy compression is more suitable here unless maintaining the quality of images is more important than the speed of transfer. For Transfer: While transferring photos from one storage device to another, using lossless compression would mean larger file sizes and slower transfer speed. The advanced algorithms of lossless compression help in this case.ģ. While getting a print of your image, it is important to pay attention to the number of pixels per inch and other technical details. For Printing An Image: If you wish to get a hardcopy print of any image, lossless compression is the way to go. The trade-off here would be the larger size of the file, but you will be able to retain its excellent quality.Ģ. In this case, where you cannot afford any reduction in the photo’s quality, go for lossless compression. The only exception is when the quality of the image you are trying to store is essential. Hence, the file takes up lesser space on your device. It allows you to remove the unwanted meta data from your image file, which reduces its size. For Storage: While storing your image files on any device, lossy compression is recommended. Let’s have a look at some particular cases and try to infer which image compression technique would work best.ġ. This feature allows you to compress your image file, with the possibility of restoring it to its exact original form at any time. On the other hand, if maintaining the quality of the image file is mandatory, lossless compression is what you should choose. It allows you to save time (uploading/transfering), frees up space (reduction in image size), and gifts you with a quicker loading time. If the quality of the image file does not hold much importance, lossy compression is more suitable. Majorly, the choice depends on your needs. Picking one of the two image compression techniques depends on a few factors. Part 2: Which Type of Compression Should You Choose? Generally referred to as irreversible compression. Lesser data-holding capacity than lossy compression technique. Lossy compression’s capacity of data-holding is higher. Makes use of algorithms like transform coding, discrete cosine transform, fractal compression, etc.Īdvanced algorithms such as run-length encoding, arithmetic encoding, Lempel-Ziv-Welch, etc. Used for compressing text, images, and sounds. Generally used for compression of images, audio, and videos. The image’s size gets reduced after compression. In lossy compression, the quality of the image is compromised. The compressed image file can be restored to its original form. Not possible to restore/rebuild the file to its original form. This method eliminates data that is unnoticeable.ĭoes not eliminate data even if it is unnoticeable.
