About
Set a new canvas by aspect ratio, exact pixel size, or per-side percentages, and the photo is placed inside it without cropping the subject. Empty edges can be filled with Smart fill options such as texture, blur, mirror, stretch, solid color, or a transparent PNG border. The AI uncrop option uses LaMa, an open inpainting model that runs in the browser; the first run downloads it once (about 62 MB) and the photo is not uploaded.
Key Features
- Expand a photo beyond its edges using per-side percentages or preset ratios
- Change aspect ratios such as 4: 5, 16:9, and 9:16 without cropping the subject
- Fill new areas with texture, blur, mirror, stretch, solid color, or transparent PNG
- Run AI uncrop locally with the LaMa inpainting model in the browser
- Export platform-sized images up to 40 megapixels for social, YouTube, and print
Use Cases
- Turning a portrait photo into a landscape banner without losing the subject
- Resizing a picture to exact Instagram, YouTube thumbnail, or X header dimensions
- Adding room around a tight photo so it fits a profile or cover frame

FAQ
Is uncrop.si really free?
Yes. Every tool that runs in your browser is free, with no sign-up, no watermark and no daily limit. That includes Smart fill, Texture fill, blur, mirror, stretch, color and transparent fills, plus the crop, resize, adjust, compress and convert tools. AI uncrop, where our AI paints the new area, is free once a day for everyone.
Is my photo uploaded anywhere?
Not unless you use AI uncrop. Your photo is decoded and processed inside your browser. Only when you press Extend with AI do smaller copies of it go through uncrop.si to the AI service we use, which paints the new area. We keep neither the photo nor the result.
Can uncropping bring back the part that was cut off?
Not by itself. An uncrop tool invents new pixels that match the photo; it cannot see what was really there. You can only recover the real pixels from the original file, an app that keeps crops reversible, or occasionally from data left inside the file. Read Can you uncrop a photo? or try the cropped photo checker.
Can I uncrop an image without AI?
Yes. Texture fill, blur, mirror, stretch, color and transparent fills use no AI at all: they fill the new border from your own pixels, with a color, or leave it transparent. Smart fill does use AI, an open model that runs on your device, and it is free too. AI uncrop, which uses a generative model run by an AI service, is optional and runs only when you press its button.
What is the difference between Smart fill and Texture fill?
Smart fill runs an open inpainting neural network on your device, so it can continue shapes and structure. Texture fill rebuilds the border from patches of your own photo, which keeps grain and detail crisp on skies, water, grass, walls and fabric. Try both; they are free.
How does AI uncrop work?
Choose AI uncrop as the fill and press Extend with AI. Smaller copies of your photo go to our AI, which paints the new area, and the studio lines the result up with your photo and puts your original pixels back on top. Everyone gets a free AI uncrop every day, no sign-up needed. See the AI image extender.
Can I use one photo in several tools?
Yes. After you uncrop a photo, pick a next step such as Resize, Compress or Add text and the result opens there straight away. It is passed through your browser's own storage on this device, never uploaded, and removed as soon as the next tool opens it.
How do I fit a photo to Instagram without cropping?
Choose Exact size, pick Instagram portrait post (1080 x 1350) or square (1080 x 1080), then fill the new area with blur, color or Smart fill. For a quick version without AI use Instagram no crop.
