Change the aspect ratio of an image without cropping
Stories and Reels want 9:16, feed posts look best at 4:5, and a landscape photo fits neither. Extend the image to the ratio the app expects so the platform does not cut it for you.

AI Image Extender
Expand an image to a new aspect ratio in one click. Upload a JPG, PNG, or WebP, pick a ratio, and the AI image extender fills the new space around your photo while the original part stays exactly as it was.

Each row starts from one image and one target ratio: the original on the left, the extended image on the right.

AfterWhat is an AI image expander?
An AI image expander adds new picture area around a photo. You choose the shape you need, and the AI reads the edges of the image and continues them: more sky above a skyline, more floor under a chair, more garden behind a person. Editors call this outpainting or uncropping. Cropping reaches a new shape by removing part of the photo, while extending keeps the whole photo and builds outward, so nothing you already had is lost. This AI image extender places your image in the center of the new frame at its full size and fills only the empty space. The original area keeps its pixels and its sharpness, so faces and small text look exactly as they did before.
How it works
How to extend an image with AI
Step 01Upload your image
Drag a JPG, PNG, or WebP image into the AI image extender from your phone or computer.
Step 02Pick the aspect ratio
Pick one of nine ratios between 16:9 and 9:16, including 3:2, 4:3, 1:1, 4:5, and 2:3, and the AI adds space on the sides that need it. Choose Auto, or the ratio your image already has, to widen the view evenly on every side.
Step 03Download the extended image
The result appears next to your upload. Check the new edges, then download the extended image with no watermark.
Where an image extender saves a picture
Most of the time an image is fine and only its shape is wrong for the place it has to go. These are the jobs people bring to an AI image extender.
Uncrop an image that was cropped too tight
Phone pictures and screenshots are often cropped close to the subject. Uncrop the image to recover space around a person, a pet, or a building and make the framing feel less cramped.
Make an image wider for banners and thumbnails
Website headers, YouTube thumbnails, and desktop wallpapers are wide. Make the image wider at 16:9 and the subject keeps its size and position in the middle of the frame.
Extend the photo background to make room for text
Ads, flyers, and slides need empty space for words. Extend the photo background on one side of the subject, then place your headline over the plain area.
Fit product photos to marketplace and ad sizes
One product photo has to serve a square listing, a 4:5 social ad, and a wide store banner. Extend the same shot to each size so the product looks identical everywhere.
AI outpainting for AI art
Liked a square AI image but need a phone wallpaper or a book cover? Outpaint it to 9:16 or 3:4 and the scene continues around the part you already like.
What's different
What sets this AI image extender apart
Before extending a photo, people usually ask whether the original will change, which shape to pick, and how much extra work it takes. Here is how this AI image extender handles each of those.
The photo itself is never redrawn
Some tools repaint the whole image to fit a new shape, and a face can come back looking like someone else. This one only paints the empty frame around your photo, which makes it safe for portraits, product shots with labels, and screenshots with text.
Auto when you are unsure of the ratio
Auto skips the choice altogether: it keeps the shape you already have and adds the same amount of new scene on every side, which gives a cramped subject room to breathe or leaves margin for a frame.
Extend straight from another result
Images made with the other tools on this site, such as the image combiner, background changer, or photo enhancer, have an extend button under the result. Pick a ratio there and the wider version appears next to it, with no download and re-upload in between.
Matching frames for a product set
On a paid plan you can extend several listing or catalog photos to the same ratio in one run, so every tile in a grid or carousel lines up without cropping any product.
AI image extender FAQ
Answers about extending images: aspect ratios, what changes in your image, prompts, quality, and privacy.
Yes, you can start for free. A new account gets free credits on sign-up, and free results are full-size images with no watermark. When the credits run out, you can buy a credit pack or subscribe to a plan.
Upload the image and choose the ratio you need. The AI image extender keeps the whole photo and adds new area on the shorter sides: a vertical photo gets more scenery left and right at 16:9, and a horizontal photo gets more above and below at 9:16. Nothing from the original is cut away.
No. Your image is placed at its full size in the center of the new frame, and only the empty space around it is generated. Faces, products, and text inside the original area stay exactly as they were.
The image keeps its shape and the AI extends it evenly on all four sides, like stepping back from the scene. Auto does the same without you having to look up the ratio. Use this when a subject sits too close to the edges or when you want breathing room for a frame or a print border.
The image extender does not take a text prompt. It continues what is already at the edges of your image, which keeps lighting, perspective, and style consistent. To put your subject in a different scene, use the AI background changer.
Photos whose edges show background extend most naturally: sky, walls, water, grass, tabletops, blurred scenery. When a person or an object is cut off by the edge of the frame, the AI has to invent the missing part, so check hands, feet, and text near the borders before you use the result.
The original area keeps its full resolution, so the part you care about looks the same as before. The new area is generated to match the light, sharpness, and grain of your image. Details far from the original, such as distant signs or patterned fabric, can come out simplified, so zoom in on the outer edges before you print the result large.
Your uploads are used only to extend your image and are not shown publicly. Extended images are stored in your account projects. Free results are kept for 7 days, paid results stay until you delete them.
