Open tool Image Aspect Ratio Calculator
Create a bounded, browser-local image aspect ratio calculator with visible assumptions, review guidance, and downloadable output.
BUILT AROUND THE TASK
Optimize website images
Prepare lighter images that still look sharp in their intended space. Work out the crop, resize to the display dimensions, and compare compression results before replacing assets on your site.
USE WITH CONTEXT
Before you use these tools
Use a copy of the original. Check the smallest text and the busiest image areas at the final display size. Measure the actual downloaded file rather than assuming a quality setting guarantees a particular size.
A PRACTICAL ROUTE THROUGH THE SHELF
From raw input to reviewed output
- 1
Match the image slot
Find the width and aspect ratio used by the page. Crop around the subject before resizing so the layout does not cut off important details.
- 2
Resize and compress
Create the needed dimensions, then adjust compression. Keep a larger source for displays that need higher pixel density.
- 3
Preview in context
Compare the new asset with the original on desktop and mobile. Check transparency, fine edges, and any text inside the image.

Questions before you start
Does a smaller image always make the page better?
Smaller files can reduce transfer size, but excessive compression or undersized dimensions can make content hard to read. Choose the smallest version that still serves the page, and check its real appearance in the layout.
