Social Media Image Resizer: the job it actually does
Create browser-based resized copies using popular social-media aspect ratios.
Aspect ratio decides whether resizing crops or leaves space
Exact dimensions can conflict with the source image’s proportions. A cover-style fit may crop edges; a contain-style fit can leave empty space. Use the preview to choose which compromise fits the destination.
Platforms can change recommended dimensions and may crop previews differently across feeds, profiles and devices.
prepare Instagram square or portrait graphics
Use it when you need to prepare Instagram square or portrait graphics; it also fits when you need to create story/reel cover dimensions. If the job asks for more than that, split the workflow rather than making one tool do two different things.
The point where Social Media Image Resizer stops helping
Use Crop Image when composition matters more than exact dimensions. Use compression when the dimensions are already correct and only file size needs work.
