How To Reduce Picture File Size On Mac

As cameras and screen resolutions increment, the photos and screenshots you take tin run across several MBs. The big file means it occupies more than space (on Mac, iCloud, SSD) and takes longer to send via Slack, email, etc. One way to address this is past reducing image file size on Mac.

Compressing and decreasing the photo size certainly lowers the picture quality a bit. Merely in most cases, you lot won't notice much difference. Hither are seven quick and complimentary ways to shrink photos on Mac one at a time or several in batch/majority.

Factors on which the image file size depends

The file size of a photo depends on various things like:

• Image dimensions: A 1920 ten 1080 image will have a bigger file size than a 720 ten 480 image.
• Image format: For most pictures, JPG/JPEG tends to have a smaller file size than PNG. But if your prototype is mainly text-based, PNG is ameliorate.
• Paradigm content and colour depth: If there are many black portions in the image instead of white, information technology can accept a smaller file size.
• Camera type: Pictures taken by the front iPhone camera or the MacBook's webcam will near always have a smaller file size than the main photographic camera, which runs into several megapixels.
• Flash: If you use wink while shooting pictures, this will result in an image with increased file size.
• Screen resolution: The screenshot file size of my new retina thirteen-inch MacBook Pro is far more than than that of my non-retina thirteen-inch MacBook Pro. This is because the sharper screen has more pixels and image dimensions, resulting in bigger screenshots.

Now that you know the basics about epitome file size, here are some quick means to convert large images on Mac to smaller sizes.

one. Reduce image file size past irresolute their format

I take dozens of screenshots on iPhone and Mac every day for my articles. By default, Apple devices take and save screenshots in PNG format.

If the screenshot merely has text (similar that of the iPhone Settings app), I almost e'er continue it in PNG format.

But if the image has graphics (similar the screenshot of Home Screen with app icons), I convert it to JPG in 99.9% of cases. JPG offers almost the same motion picture quality as PNG just significantly reduces file size. Sometimes the file size reduction is up to 98%!

In the steps beneath, yous will see how to change the image format. If you lot already know how to convert images from one format to another, you may too use those methods.

And if you accept lots of screenshots, you can use an piece of cake Last command to change Mac's screenshot format to reduce size.

Like if you're converting PNG to JPEG. If you lot stay with the same format, choosing Actual Size won't reduce the file size past much.

five) Finally, click Convert to [Format Name] to reduce the image file size and relieve information technology in the aforementioned location as the original files.

Tip: Click "Size" on tiptop of the Finder folder to sort them by file size.
