Until that technological nirvana gets here (and don’t bother to hold your breath), we still need to squeeze the size of files, particularly photos for websites. While most Mac graphic apps compress JPG or JPEG photos with ease, sometimes quality suffers. Here’s a solution.
Big Difference, A Mini App
JPEG compression is a technique known as lossy compression; which means as the file size is compressed, or reduced in size, the quality of the image drops.
It’s just math. You can only squeeze so much blood from a turnip, right? So, when it comes to putting photos on the web, there’s a sweet spot between reduction and quality.
Enter JPEGmini, a single purpose Mac utility that compresses JPEG photos to a point where the file size is the lowest where the image quality is the highest, or not easily discernible as different from the original.
That’s the objective. JPEGmini often reduces 5MB files to less than 1MB; up to one fifth the file’s original size without notable artifacts or visible blemishes.
Just drag and drop the photo you want to compress onto JPEGmini and watch as it does the deed and shows you how much total space you’ve saved.
For many, JPEGmini is a good way to save space on today’s storage restricted MacBooks with SSD drives, and for that, it works well.
It’s also a good way to reduce photo file sizes for photographers who need the smallest file size to be displayed on a website, but still need higher than normal quality. That’s where JPEGmini excels (and the option to batch compress a folder of photo files).
It takes a better than average eye for details to see the difference between a JPEGmini compressed photo and the original at five times the size.
That said, there is a point of diminishing returns. Most Mac graphic apps will compress photos using JPEG technology, but the trade off is photo quality diminishes as file size goes down. JPEGmini strikes that perfect balance between the two.
