If you constantly need to reduce image size in KB, this post recommends two desktop tools for Windows and Mac. For professional and efficient compression, see two software worth trying.

Step 1.Open the app on your computer and upload the image by dropping it from the folder. After uploading, go to the "File" menu and click the "Save for Web" button.

Step 2.When the dialog box appears, choose the output format, quality, and other settings. Click the "Save" button to apply all the changes and save the compressed picture to your device.

2. Preview on Mac

If you are a Mac user, using Preview to shrink the image size to 100 KB is best. It is the default photo viewer and provides editing features, such as drawing tools and an image resizer. Unlike Photoshop, Preview is user-friendly and free to use but, unfortunately, only available for Mac versions.

Step 1.Open Finder and select the image you want to compress. After opening the photo on Preview, go to the "Tools" menu at the top toolbar and choose "Adjust Size".

Step 2.Use the unit of measurement accordingly. Options include resizing the image by pixel, inch, and percentage. Click the "OK" button to apply all the changes.
