How Resize Works

Scale images to exact pixel dimensions for thumbnails, banners, avatars, or form uploads. Enter width and height, optionally lock aspect ratio, pick Fill / Fit / Stretch / Cover / Contain, then download the resized file. ImageToolkit resizes on the server so the output file actually has those pixels.

Step 1: Upload the image to scale

Choose the photo or graphic that needs new pixel dimensions.

Step 2: Enter width and height

Type exact pixel values. Lock aspect ratio when you want clean proportional scaling, then choose how the image should fill the box.

Step 3: Server-side resize

ImageToolkit scales the image to your dimensions and prepares the output file.

Step 4: Download the resized file

Save the image at the new size for web, print presets, or upload limits.
