## Why Correct Image Dimensions Matter for Social Media

Every social media platform displays images differently. If you upload an image with the wrong dimensions, it will be cropped automatically — often cutting off important parts of your composition, text overlays, or branding elements. This creates an unprofessional look and can hurt engagement. Using a [social media scheduler](https://posteverywhere.ai/social-media-scheduler) that handles multiple platforms means getting image dimensions right for each one.

Correctly sized images also load faster and render at higher quality because the platform does not need to recompress or resize them server-side. For ads and promotional content, using the recommended dimensions can improve click-through rates by ensuring your visuals display as intended across all devices. Combine properly sized images with content scheduled at the [best time to post](https://posteverywhere.ai/best-time-to-post) for maximum impact.

Our image resizer uses client-side Canvas API processing with high-quality interpolation to resize and center-crop your images to the exact pixel dimensions each platform recommends — without uploading anything to a server. Once resized, use our [cross-posting feature](https://posteverywhere.ai/cross-posting) to share your content across multiple platforms efficiently.
