Common Practical Use Cases
- Social Media: set an upload to an exact 1200 by 630 open graph size before scheduling a post.
- CMS Uploads: match a thumbnail to the pixel dimensions a content template expects so it is not scaled in the browser.
- App Store Assets: produce a screenshot at the precise width a store listing requires without opening a design app.
- Avatar Preparation: scale a profile photo down to a square target while the aspect lock keeps the proportions honest.
Frequently Asked Questions
