About Custom Banner Maker

Most banner tools assume you already know the platform's standard size. This one is for everything else: a storefront header, community cover, email strip, website hero, or a size that a form gives you in pixels. Set the exact width and height, then drag and zoom your image until the important part sits inside the frame. The result is rendered entirely in your browser, so the original image never goes to an upload server.

How it works

  1. Enter the width and height the destination requires. The starting size is 2400 by 600, but both fields accept any practical banner dimensions.
  2. Choose an image, then drag it inside the frame and use the zoom slider to set the crop.
  3. Save as JPG for a smaller file or PNG when the source needs transparency. The download has exactly the dimensions entered.

In practice

A 2400 by 600 website header

Enter 2400 and 600, position the artwork inside the wide frame, and download a file that is ready for a site header without trial-and-error exports.

A size supplied by a platform or form

When a destination gives you an unusual required size, enter those exact pixels rather than resizing several times and hoping the final crop fits.

What to watch for

Questions

Can I make a banner at any size?

Yes. Enter the exact width and height in pixels, then download a banner at those dimensions.

Why is part of my image missing?

The image covers the full banner frame, so a source with a different shape is cropped at its edges. Drag and zoom it to choose what stays visible.

Does the image get uploaded?

No. The image is read, positioned, and rendered locally in your browser.
