To reduce the size of a picture, you can use several methods depending on your device and tools available:

Online Image Compression

• Upload your image to an online image compressor.
• Choose the image format (PNG or JPG) and set the desired quality level.
• Start the compression process to reduce file size without changing dimensions significantly.

Using Microsoft Paint (Windows)

• Open the image in Paint.
• Use the "Resize" option in the Home tab.
• Choose to resize by percentage or pixels while maintaining the aspect ratio.
• Save the resized image as a new file to reduce its size

Using Microsoft Office

• Select the picture in your document.
• Go to the Picture Tools Format tab and click "Compress Pictures."
• Choose compression options to reduce file size within Office applications

On Mac (Preview App)

• Open the image in Preview.
• Use Tools > Adjust Size to resize the image dimensions.
• Save the resized image to reduce file size

On iPhone

• Change camera settings to capture photos in High Efficiency format (HEIF) to reduce future photo sizes.
• For existing photos, use a free app like "Compress Photos" from the App Store to compress and reduce file size without major quality loss

General Tips

• Reducing pixel dimensions (width and height) lowers file size.
• Compressing images reduces quality but saves space.
• Choose JPEG format for photos for better compression.
• Always keep a backup of the original image before resizing or compressing.

These methods allow you to reduce picture size either by resizing dimensions or compressing the file to save storage or improve upload times. Choose the method that best fits your device and needs.
