Set the exact width and height of your image in pixels.
Resize Image Dimensions
Resize photos by pixel width and optionally height, keeping aspect ratio when needed.
How to use this tool
Upload an image, enter pixel dimensions, preserve aspect ratio if needed and export the resized image.
Before you download
Upscaling cannot restore missing detail; extreme dimension changes can affect clarity.
Example workflow
A 1200 × 800 image can become 600 × 400 without changing its shape. Keep the ratio locked for proportional resizing. To create a square output, crop to a square first rather than stretching the rectangular source.
Check your result
Pixel dimensions and file weight are separate requirements. Once the dimensions are correct, compress the export if it still exceeds an upload limit. Enlarging a source adds pixels without guaranteeing additional real detail.
