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?

It is designed to generate new background outside the current frame rather than crop the subject, but exact preservation is not guaranteed. Compare faces, products, logos, and text with the source 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.
