Built for creators on Instagram, TikTok, and Pinterest who need to reformat images quickly.
See the Canvas Grow
A source image stays intact while AI generates the surrounding space for a new platform-ready frame.
ImageFit AI uses advanced AI outpainting to extend your image in supported directions. Unlike cropping or stretching, the AI generates new pixels that blend naturally with your original photo — preserving your subject while growing the canvas. Whether you're reformatting for Instagram, TikTok, or Pinterest, the result looks like it was always that size.
AI expansion, not stretching
The original image remains the source of truth. ImageFit AI grows the canvas around it so the final frame fits a supported social ratio.
How It Works
Most image resizers crop or squish your photo to fit a new ratio. ImageFit AI does the opposite: it keeps your original image intact and uses generative AI to fill in the areas outside the original frame. The result is a seamlessly extended image — not a distorted one.

FAQ
Answers to common questions before you start expanding images.
What is an AI image expander?
An AI image expander is a tool that uses artificial intelligence to extend the borders of an image beyond its original edges. Instead of cropping or stretching, the AI generates new content that blends naturally with the existing photo. ImageFit AI expands your image to supported aspect ratios while keeping the original subject intact.
Can I try the AI image expander for free?
Yes. ImageFit AI offers free credits for eligible new users, with no credit card required. Additional credits are available as one-time packs or as part of a monthly subscription.
What image formats does the expander support?
ImageFit AI accepts JPG, PNG, and WEBP files up to 10MB. The output is delivered at downloadable resolution, ready to upload directly to Instagram, TikTok, or any other platform.
Does the AI image expander work on photos of people?
Yes. The AI is designed to handle portraits, product shots, landscapes, and artwork. It preserves the main subject of your photo while extending the background or surroundings naturally. For best results, make sure the subject is not at the very edge of the original frame.
Is there a size limit on the images I can expand?
Yes. The current upload flow accepts supported image files up to 10MB. If a file is too large or unsupported, the app will show an upload error or ask you to try a smaller file.
Can I expand an image without a text prompt?
Yes — no prompt writing is needed for the standard workflow. You select one of the product's supported ratios or presets, and the AI handles the expansion process.
