What Lampdra Extend does
Powerful features, simple to use

Directional extension

Extend the background left, right, up, down or in all directions simultaneously.

⚡

Intelligent fill

The new background area is filled intelligently by analysing the existing background content and continuing it naturally.

🎯

Aspect ratio presets

Choose from common aspect ratios — 16:9, 1:1, 4:5, 9:16 — and the extension is calculated automatically.

Your original image and subject are always preserved exactly. Only the new extended area is generated.

Frequently asked questions
How far can I extend a background?+
You can extend the background by up to 100% of the original image dimensions in any direction. For example a 1000px wide image can be extended to 2000px wide.
Does the extension look natural?+
Yes. Lampdra Extend analyses the existing background and fills the new area with content that continues naturally from the original — matching colour, texture and perspective.
Can I extend in multiple directions at once?+
Yes. You can extend left, right, top and bottom simultaneously to reach a new canvas size from all sides at the same time.
Is Lampdra Extend really free?+
Yes, completely free. Lampdra Extend is supported by a short ad shown before you download your result. That ad revenue keeps the service free for everyone. You never need to pay, sign up or share your email.
Are my images private?+
Lampdra Extend processes everything in your browser. Your image is never uploaded to any server. We cannot see, access or store your photos. Everything stays entirely on your device.
Can I use it on my phone?+
Yes. Lampdra Extend is fully mobile-optimised and works in any modern browser including Chrome and Safari on iOS and Android. No app installation is required.
