Letting the platform crop means letting it choose for you
Sinh Vũ doctrine, article 2.06: test a design at the size customers will actually see, before approving it at working-screen size.
Platforms crop the middle
A landscape image posted into a square or portrait frame loses both sides. A product standing off to one side is gone.
The interface covers the text
In stories and vertical video, the account name covers the top while buttons and captions cover the bottom. Text near the edges gets hidden.
Heavy images load slowly
A camera photo is dozens of times heavier than needed. If the platform recompresses it, it blurs; on a website, it loads slowly.
What people often ask
Three questions Sinh Vũ often gets about this tool.
Is my image sent anywhere?
No. The image is cropped and compressed in your browser and is not uploaded to any server.
Where do these sizes come from?
They are the common sizes platforms recommend as of October 2026. Platforms may change them; Sinh Vũ updates the tool when they do.
What if the crop misses the right spot?
Tap the original image in the left panel to set the focal point. Every format is recropped around it.
