Aspect Ratio Cropper
Create an exact focal crop for a chosen aspect ratio.
BUILT AROUND YOUR WORK
Deliver a web-ready asset pack. Start with licensed source images and the destination dimensions. Use the relevant tools below to resize assets and check color combinations, then keep reviewed exports with a reusable palette alongside the source material.
USE WITH CONTEXT
Preview at the intended output size, preserve an editable master, and confirm licensing and accessibility before publishing creative assets.
A PRACTICAL ROUTE THROUGH THE SHELF
Bring licensed source images and the destination dimensions. Record where the values came from and which assumptions are still uncertain.
Choose a tool to resize assets and check color combinations. Read its method and limits, then run a small example before working through the full scenario.
Keep reviewed exports with a reusable palette. Inspect small-screen rendering, transparency, text contrast, and image detail.

For this workflow, begin with licensed source images and the destination dimensions. Choose the tool whose inputs match the task, rather than entering incomplete values into a broader calculator. The intended outcome is reviewed exports with a reusable palette.
Inspect small-screen rendering, transparency, text contrast, and image detail. Preview at the intended output size, preserve an editable master, and confirm licensing and accessibility before publishing creative assets.
