Resizing an image to exact pixel dimensions is essential for social media posts, website banners, product listings, and print materials that require specific sizes. Our free image resizer lets you set precise width and height values, choose how the image fits within those dimensions, and control output quality — all without installing any software.

Choose from multiple fit modes: cover crops the image to fill the exact dimensions, contain fits the whole image within bounds (adding letterboxing if needed), and fill stretches the image to match exactly. Download your resized image instantly in JPEG, PNG, WebP, or AVIF format.
