Why Resizing Image Dimensions is Crucial for Web, Documents & Social Media
Uploading oversized photos to websites, job portals (like CPNS or university admissions), or social media leads to rejected applications, slow page loading, and cropped images. Our free Online Image Resizer lets you scale image width and height with pixel perfection while locking aspect ratio to prevent distorted stretching.
