About This Tool
Prepare social-media graphics by checking dimensions, proportions and optimization considerations for common sharing contexts. Use the output as a practical pre-publish checklist for visual assets.
How to Use It
Add or enter the asset information requested by the tool, review the detected dimensions and optimization guidance, then export and test the final image on the target platform.
How It Works
Social platforms may crop or transform images, so correct dimensions alone do not guarantee the final appearance. Keep important text and branding inside safe visual areas and use an appropriate file format.
Practical Example
A landscape promotional graphic can be resized to a platform-appropriate dimension while keeping its important headline inside a safe area so cropping does not remove it.
