This way, you will create a new JPEG, which will be reduced in size, but its quality will be retained, as much as possible.ĭifferent file formats are used for different types of visual content depending on how they sustain compression.

Here is how to reduce JPEG file size in Preview: Lossless compression means that the image quality will be retained, while as a result of a lossy compression, some photo data will be lost, impacting its quality. Reduce photo size by reducing resolution using PreviewĮvery macOS has a version of Preview, an image and PDF viewing app which lets you look over and print images or PDF files, as well as edit all kinds of image formats.īefore you begin to compress a JPEG, note that there are two types of image compression: lossless and lossy. The Screen (72 DPI) option results in the smallest file size, but is only recommended if the file is intended for viewing only (e.g., when sending a preview for approval).Let’s get into the details of how you can quickly and easily shrink JPEG file size on Mac.
For example, it is a good option for a newsletter distributed over email or as a website download. It produces a much smaller file, but the quality is still adequate for printing and zooming in on the images. The Low (150 DPI) option may be used if your document will be distributed over the internet.
The Good (300 DPI) option is the recommended setting for non-demanding tasks, as the quality is sufficient for both commercial and home printing, while the file size is relatively small. Use this setting if your PDF will be used for high-quality printing (either at home or at a printshop). The Best (600 DPI) option means that all images will be rasterized, and the resolution will be set to 600 DPI. However, if your document includes a lot of high-resolution photos, use it with care because the PDF file size might dramatically increase in size. Usually, this option provides the best quality and is highly recommended if your document contains vector images (to prevent them from being rasterized). The Original option means that all the images in your document will be retained in the PDF as they are, without any modification.
