About this tool
Resize images to exact dimensions or percentages. Lock aspect ratio to prevent distortion, or use presets for common sizes. Works with all major image formats.
Resize for Any Purpose
Whether you need passport-sized images, wallpaper dimensions, or thumbnails for a blog, the Image Resizer handles it all. Enter exact pixel dimensions, a percentage scale, or choose from common presets. Aspect ratio lock prevents any distortion.
Pixel Dimensions vs. Percentage
Use pixel dimensions when you need an exact size (e.g. 1920×1080 for a banner). Use percentage when you want to scale proportionally — 50% of any image gives you half the width and height with perfect proportions preserved.
