Social Banner Sizer
Fit one uploaded image into common social banner sizes without uploading it.
Fit artwork to common banner ratios for one focused image job
Social platforms use different banner dimensions, and a graphic that works on one surface can crop badly on another. This sizer places your uploaded artwork into a selected canvas size and uses cover-style math so the banner is filled without empty bars.
For example, upload a wide brand graphic and export it as 1500 by 500 for a profile banner or 1200 by 630 for a link preview. The preview shows what part of the image remains visible after fitting.
Output limits and privacy
The tool does not know each platform account layout, profile-photo overlap, or mobile crop variation. Keep logos and important text centered. The fit preview is generated locally, so private brand artwork can be checked against common banner ratios before export. The cover-fit preview makes cropping visible before you discover the problem inside a platform uploader.
