Banner Extender: how to use it
- Drop in a photo.
- Choose the Banner size: X/Twitter header, LinkedIn cover, Facebook cover, YouTube channel art, website hero, story or Pinterest pin.
- Extend. The photo is kept whole and the extra space is filled in, at exactly the size chosen.
Tips
- Keep the main subject in the middle third: cover images are cropped differently on phones and desktops.
- If the photo is already that shape, there is nothing to extend; use the Image Resizer to set the exact size.
Banner Extender: what it does and when to use it
Headers and covers are wide and short: an X header is 1500 × 500, a LinkedIn cover 1584 × 396, YouTube channel art 2560 × 1440. Most photos are not that shape, and cropping them to fit throws away the subject. The Banner Extender keeps the whole photo, places it on a canvas of exactly the size you choose, and fills the extra space at the sides or top and bottom with an inpainting model so the scene continues.
The output is delivered at the exact pixel size of the platform you picked, ready to upload. If your photo is already that shape, there is nothing to extend, and the tool tells you to resize it instead.
Profile pictures, buttons and text overlays cover parts of most headers, so keep the important part of the photo near the centre. As with any outpainting, simple edges such as sky, sea, grass or a plain wall extend convincingly; faces, text and buildings cut by the edge do not. For other shapes, Uncrop / Expand offers common ratios, and our social media image sizes guide lists current sizes.
Banner Extender: frequently asked questions
Is the Banner Extender free, and do I need to sign up?

Will my photo be cropped?
No. The whole photo is kept at full resolution in the middle, and only the new area on the sides or top and bottom is filled in, to exactly the banner size you chose. Related tool: Uncrop / Expand.
How do I make a photo fit a YouTube banner or LinkedIn cover?
Pick the banner size and the photo is placed in the middle at full resolution, with the missing space on the sides filled by AI to match the edges. Nothing is cropped. Check the safe area of each platform in our social media image sizes guide.
What size is a YouTube banner?
2560 by 1440 pixels, but only the middle 1546 by 423 pixels shows on every device, so keep text and faces there. Other platform sizes are listed in our social media image sizes guide.
