How it works
1 · Upload Your Image
Drop in any photo — JPEG or PNG. No minimum resolution required, though higher resolution input produces sharper results.
2 · Set the Target Dimensions
Choose a preset aspect ratio (16:9, 4:3, 1:1, 9:16) or enter custom pixel dimensions. The tool calculates how much canvas to add on each side.
3 · Describe the Extension (Optional)
Add a prompt to guide what fills the new area — 'blue sky with light clouds' or 'continuation of the wooden floor'. Leave it blank and the model infers from context.
4 · Generate and Download
Flux Kontext Pro renders the extended image in seconds. Review the result and download the full-resolution file.
What it costs
Flux Kontext Pro starts at 8 credits per output at default settings. Check your settings and total in Studio before running.

Made for
Social Media Managers
A social media manager repurposing a single photo across Instagram (square), LinkedIn (landscape), and Stories (portrait) can expand the canvas to fit each format without re-shooting or awkward cropping.
Ecommerce Sellers
An ecommerce seller with product photos shot in portrait can convert them to 16:9 landscape for banner ads or hero images without losing the product in the frame.
Photographers
A photographer who framed a shot too tightly can recover the composition — add foreground, extend the sky, or reveal more of the scene that was cut off.
Web Designers
A web designer who receives a stock image in the wrong aspect ratio for a client's hero section can expand it to fill the layout rather than searching for a replacement image.
YouTubers and Video Creators
A YouTuber can take a portrait-mode selfie or product photo and expand it to 16:9 for use as a thumbnail background, saving a separate shoot.
