Resizing is different from compression: resizing changes the pixel dimensions of an image, while compression mainly reduces file size. For best results on the web, resize overly large images first and then compress them if you also need a smaller file.
Questions
Should I keep the aspect ratio when resizing?
In most cases, yes. Keeping the aspect ratio prevents photos and graphics from looking stretched. Use exact dimensions only when a platform requires a specific size.
What image size should I choose for a website?
Choose the smallest dimensions that still look sharp in the layout. For example, do not upload a 4000px photo if it will only display at 800px wide on the page.
Does resizing reduce file size?
Usually yes, because smaller pixel dimensions contain less image data. However, file size also depends on the output format and compression settings, so resizing and compression are often used together.
Can I resize images for social media or ecommerce?
Yes. Many platforms recommend specific image dimensions for profile photos, cover images, product pictures, thumbnails, and posts. Resizing helps prepare images before upload and avoids unwanted cropping.
