Why do you need to resize images and when should you use them?

Resizing an image is a basic but important operation in many cases. Website optimization: Images that are too large slow down page loading, affecting SEO and UX. Resize to actual display size reduces capacity by 50-80%. Social media: Each platform has a different optimal size. Correctly sized photos display best, without cropping or blurring. Email marketing: Images in emails need to be small to load quickly. Resize to 600-800px width is enough. Printing: Need large enough image (300 DPI). Resizing up can break the image, so start with a large original image. Storage: Photos from camera/phone are often very large (4000+ pixels). Resize down to save storage space. This tool helps you resize quickly with optimal quality.
