3 Efficient Ways to Compress Photos on MacĮveryone recognizes how important it is to compress photos, therefore, you can only expect that you cannot run out of options in this regard. Everyone would have opted for losslessly compressing their images, but there's a catch-it can't compress your photos and reduce their file sizes as much as lossy compression. This is usually accomplished by eliminating superfluous metadata from PNG and JPEG files. Lossless compression implies that you may lower the size of a picture without sacrificing its quality. Just as the name implies, it is a technique of data compression that the image quality still remains after compression. However, lossy compression becomes noticeable when a file you modify and resave a file multiple times. Although the file no longer contains the same amount of data as it had before compression, this is usually not visible, even if the image's resolution has decreased. The compression algorithm removes any data it deems unnecessary from the image, resulting in a smaller file size. Lossy compression is a technique of data compression in which the file size is reduced by removing data from the file, i.e., image quality is sacrificed in order to reduce file size. Types of Compression: Lossy Compression and Lossless Compression Lossy Compression It is way faster to share a picture of 2MB on Facebook than a 20MB picture.

Bear in mind that the scale function resizes based on aspect ratio. You should see it copy the file over and then resize it. Right click on any image, point to the “Services” option at the bottom of the context menu, and then choose “Resize”-or whatever you named your service. When you’re done, save the service and name it whatever you’d like-we’re going with “Resize.” Step Two: Put Your New Service to Use If you’d rather stick to a single size, you can leave this unchecked and type in the size you always want to use. This will make the service open a dialog asking for the image size. To make it work, click “Options” on the Scale Images service, and select “Show this action when the workflow runs.” You should now have two actions in the service. If you want to resize them in place and replace the originals, leave this copy block out. By default, the action will just make copies of the resized images and save them to the desktop (or another folder of your choice). Automator will prompt you to add a block to copy files over before resizing, which is handy to prevent accidental resizing, such as missing a 0 and losing all the image quality. In the search box at the top of the left pane, type “Scale Images” and then drag the “Scale Images” action into the main panel.
