1. Use a compression tool: There are many free online tools available that can compress your image files without requiring you to download any software. Some popular options include TinyPNG, Compress JPEG, and Optimizilla. To use these tools, simply upload the image you want to compress, and the tool will reduce the file size while maintaining the quality of the image.

   

2. Change the image dimensions: Another way to reduce the size of an image is to change its dimensions. Most operating systems, including Windows and macOS, have a built-in image viewer that allows you to resize images. To do this, right-click on the image file and select “Open with” and choose the image viewer. Once the image is open, select the “Resize” or “Rescale” option from the menu and choose a smaller size. This will reduce the overall file size of the image.

It’s worth noting that both of these methods may result in a loss of image quality, so it’s important to experiment with different compression or resizing settings to find the right balance between image quality and file size.
