A smaller image is quicker to share and quicker to download (or just view on Facebook, Instagram or just download via email). If the image(s) are part of a presentation, a smaller image can make the entire presentation smaller and easier for more computers to process.
How to Resize a Picture on iPhone!
When working with images on your computer, you will sometimes see selectable arrows on the sides and/or corners of the image. You can easily move the arrows to get the right size. However, this is not the best way to resize images because it stretches (or compresses) the image, making it look blurry, fuzzy, and pixelated.
A better way to resize your image is to use image editing software. This will give you more control over the image quality, making the resized image look polished and professional.
The quality of your resized image depends on the original image you are working with. Image files (PNG, JPG, TIF, etc.) are the best type of images to resize because they tend to contain more detail. More detail means a higher resolution, making it easier for the software to resize the image without losing any detail.
