Tools that use Seedream 4.5

AI Photoshoot

Photo

Upload one to four photos of yourself, choose a concept, a framing and a grade, and get up to four matching shots per run, with your face kept from the photos.

Image to Image

Photo

Upload a picture and describe what to make from it. Keep its layout, its subject or only its style, and get a new image on Nano Banana, FLUX.2 or Seedream.

AI Baby Generator

Photo

Add one photo of each parent, pick an age, and see a portrait of a child who mixes your features: eyes, hair, skin tone and face shape. A playful guess, not science.

Photo Enhancer

Photo

Fix a dark, flat, noisy or slightly soft photo in one step. Pick what to improve, and the picture keeps its people, framing and content.

AI Age Predictor

Photo

Choose an age between 10 and 80 and see your selfie made older or younger to match. Skin, hair and face shape change; your identity, pose and background stay.

AI Headshot Generator

Photo

Upload one to three clear photos of yourself, pick an outfit and a backdrop, and get a head-and-shoulders portrait in studio light, ready for your LinkedIn profile, CV or company site.

YouTube Thumbnail Generator

Image

Write the video title, a short line of text and the expression, add your photo if you want to be in it, and get a 16:9 thumbnail with lettering big enough to read on a phone.

AI Portrait Generator

Photo

Upload a photo of a person and choose how the portrait should look: oil on canvas, a film still, a fashion editorial, a watercolor or a black and white study. The face stays theirs.

AI Product Photos

Photo

Put your product on a kitchen counter, a studio backdrop or a holiday table from one simple snapshot. The prompt keeps its shape, colors and label as they are.
