How can I compress image size under 100kb without losing quality

Using the Microsoft Photos app is a straightforward, built-in way to compress image size on Windows 10.

Instead of just changing the image's dimensions (making it smaller in width and height), the Photos app allows you to compress image size by lowering its quality. This is a "lossy" compression method, meaning it permanently removes some image data. The clever part is that by adjusting a simple slider, you can find a sweet spot where the file size is significantly reduced, but the loss in quality is virtually unnoticeable to the human eye.

Step-by-Step Guide to Compress an Image

1. Open Your Image: Locate the image you want to compress in File Explorer, right-click on it, select "Open with," and then choose "Photos" from the menu.

2. Find the Resize Tool: Once the image is open in the Photos app, look for the three dots (...) in the app's top-right toolbar. Click it, and then select "Resize image" from the dropdown menu.

3. Adjust the Compression Settings: A new window will pop up. Here's where you control the compression:

• Quality Slider: This is your primary tool. Drag the slider left (towards "Low") to compress image size more aggressively, resulting in a smaller file. Drag it right (towards "High") to preserve more quality.
• Dimension Options: You can also change the image's width and height, either by pixels or as a percentage.
• Real-time Preview: The most helpful feature is at the bottom of this window. It will show you the current file size next to the new estimated file size as you make adjustments. This lets you experiment with the quality slider to see exactly how much space you will save before you commit.

4. Save Your Compressed Image: Once you are happy with the balance between quality and file size, click "Save resized copy." The app will then create a new, smaller version of your image, leaving your original file untouched.
