Keep important content crop-safe
Platforms resize and crop images across phones, desktop layouts, previews, and profile grids. Keep faces, logos, and text away from the outer edges. Export in sRGB and preview the post on the target platform before publishing.
常见问题
Do social media image sizes change?
Yes. Platform display rules can change, so verify critical campaigns in the current publishing interface.
Should I use PNG or JPG?
Use JPG for photos and PNG for graphics or text when the platform accepts it.
Why is my image cropped?
The displayed container and source aspect ratio differ, or interface elements cover part of the image.
