FAQ

Frequently Asked Questions

What is a photo extender?

A photo extender is a tool that expands a photo beyond its original borders by generating new background content, so you can change its aspect ratio without cropping out your subject or stretching the image.

Is Photo Extender really free?

Yes. Smart Extend runs entirely in your browser and is free with no sign-up, no credits, and no watermark. An optional AI Outpainting Pro tier is coming soon for more advanced generative results.

Do my photos get uploaded to a server?

No. Smart Extend processes your image locally, right there in your browser. Your original file never leaves your device, which also means it works even without a fast internet connection.

What image formats and aspect ratios are supported?

Photo Extender supports JPG, PNG and WebP files, and can extend to 1:1, 4:5, 16:9, 9:16, 21:9 or any custom aspect ratio you specify.

How is Photo Extender different from Adobe Firefly, Canva or Fotor?

Photo Extender's free Smart Extend runs instantly in your browser with no account, no daily limits and no upload step. Firefly, Canva and Fotor use server-side generative AI which requires an upload and often a subscription for full-resolution, watermark-free exports.
