Crop images to a wide 3:1 banner frame
The 3:1 aspect ratio is an extremely wide format commonly used for banners and header images. Because the image is three times wider than it is tall, it creates a horizontal strip that works well for website layouts and promotional graphics.
Cropping an image to 3:1 allows you to transform regular photos into clean banner visuals that fit neatly across the top of pages or marketing materials.
This tool lets you quickly crop images to the 3:1 ratio while keeping full control over the composition.
All processing happens locally in your browser, so your images remain private and editing stays fast.
Why the 3:1 ratio works well for banners
Wide banner sections appear across many digital interfaces. The 3:1 ratio provides enough horizontal space for visuals while leaving room for text overlays and branding elements.
This format is commonly used for:
- website header images
- landing page hero banners
- email newsletter banners
- marketing graphics
- promotional covers
Because of its horizontal emphasis, the 3:1 format works best when the composition highlights a central subject or a panoramic scene.

How to crop an image to 3:1

Add an image by dragging it into the tool, selecting it manually, or pasting from the clipboard.

Open the Edit view to reposition the image inside the wide banner frame.
Inside the editor you can:
- drag to reposition the scene

Common uses for 3:1 images
Website headers
Many websites display wide banner images across the top of the page. Cropping images to 3:1 ensures they fit neatly within these header sections.
Landing page hero banners
Landing pages often feature large hero sections that introduce the main message of the page. The 3:1 format provides room for both imagery and text overlays.
Email newsletter banners
Email newsletters often include a wide graphic at the top of the message. A 3:1 crop creates a clean banner that fits well in email layouts.
Marketing graphics
Promotional graphics and advertisements sometimes use wide banner formats to highlight products, announcements, or events.
Composition tips for banner images
Leave space for text overlays
Banner graphics often include titles, slogans, or calls to action. Leave open space in the composition where text can be added later.
Focus on a clear central subject
Because the frame is very wide, a strong focal point helps guide the viewer’s attention.
Use horizontal elements
Scenes that naturally extend horizontally work best in banner layouts, such as:
- landscapes
- skylines
- product displays
- group photos
Avoid placing key subjects near the edges
Important elements placed too close to the edges may get cut off in responsive layouts.
3:1 crop use cases
This tool is especially helpful when preparing images for:
- website header banners
- landing page hero images
- email newsletter covers
- marketing banners
- promotional graphics
Cropping multiple images to the same banner ratio helps maintain visual consistency across marketing materials.
How 3:1 cropping works
The tool calculates a 3:1 crop rectangle based on the original image dimensions.
You can reposition and zoom the image within this frame before exporting the final crop.
Only the selected portion of the image is exported while the rest of the original image is removed.
All processing happens locally in your browser using the original image data.
