How to judge an AI image extender
Add the source image
Use JPG, PNG, or WEBP files up to 10 MB. You can stage up to 5 images in one batch.
Pick the canvas
Choose the exact output ratio before generation: square, portrait, vertical, widescreen, banner, or standard.
Guide difficult edges
Add a short direction when the border has floors, walls, signs, shelves, hands, or other details the AI must continue.
Generate and inspect
Check the original subject, corners, lighting, and any text before downloading or using the result commercially.
What makes a good AI image extender
For real production use, speed is not the only criterion. The workflow needs predictable canvas choices, clear credit cost, batch handling, result inspection, and no unsupported promise that every image will work perfectly.
Where AI Image Extender fits
This site is optimized for upload-first ratio conversion. It is strongest when the source has continuous background and the user knows the target platform size before generating.
Quick answers
Is AI Image Extender free to start?
Yes. You can upload and prepare images before sign-in. A free account includes 5 monthly credits, and each finished outpainted image uses 1 credit.
Does it crop or change the original subject?
The goal is to keep the original pixels untouched and generate new background outside the current frame. Always inspect faces, products, logos, and text before publishing.
Which images work best?
Continuous backgrounds such as sky, walls, floors, studio surfaces, rooms, and simple product backdrops work best. Busy borders need a prompt hint or a cleaner crop.
