Procedure Edit an Image

Procedure 9: Edit an Image

This procedure changes one thing in a finished picture, such as a color or an object, and keeps the rest.

Before you start: save your Replicate key under Image in Settings, and have a finished picture in the Image feed.

Cost: about 1 to 4 cents per edit, depending on the model. FLUX Kontext dev, the first choice, costs about 2.5 cents.

Steps

1. On the main screen, tap Image and find the picture.
2. Tap Edit... on its card.
3. Under What should change?, write one short, direct instruction, such as change the white window frame to dark green.
4. Keep FLUX Kontext dev under Editing model, or choose another. The cost line shows the price of one edit.
5. Tap Edit. The app uploads the picture to your Replicate account and starts the edit.
6. The edited picture appears as a new card that begins with Edit of: and the original's prompt. Save or share it as usual.

Use reference photos

Seedream 4.5, Qwen Image Edit Plus and 2511, FLUX.2 dev and klein, and P-Image Edit take more than one picture. The picture being edited is image 1, and reference photos from the phone become image 2, image 3, and so on.

1. Tap Edit... on the picture and choose one of those models.
2. Tap Add a reference photo and pick a photo, such as an outfit, a logo, or a place. Repeat for more, up to the model's limit: 14 pictures in all for Seedream 4.5, 5 for FLUX.2, and 3 for the others.
3. Name the pictures in the instruction, for example: Dress her in the outfit from image 2. Keep her face and the background the same.
4. Tap Edit.

Say what to take from each reference photo and what to leave. In a test, Put the tiger logo from image 2 as a small patch on her denim jacket also borrowed the tiger's glasses and tie; adding only the logo, nothing else from image 2 keeps the rest out.

In API CALL, these models show each attached picture as Image 1, Image 2, and so on, with Remove on each and Add another photo.

Change the shape of a picture

Editing keeps a picture's own shape. To make a picture wider, taller, or square without changing what is in it, expand it instead.

1. On the picture's card, tap Expand....
2. Under New shape, choose a shape, such as Wide 16:9.
3. If you like, say what the new area should show, such as more of the beach and the sky.
4. Tap Expand. The result, about 4 cents, appears as a new card at the original's full resolution. The original picture sits unchanged in its middle.

In Chat, choose the picture with Talk about this or the photo button, then write make it wide or make it 9:16. The job card lets you pick the exact shape before Generate.

Edit a photo from your phone

1. On the main screen, tap Image, then the photo button at the left of the message bar.
2. Pick the photo. It appears in the Image feed as Your photo.
3. Choose Edit it, then follow steps 3 to 6 above.

In Chat, the same photo button works with plain words. Pick the photo, then send an instruction such as make it black and white. The job card names the photo, and Generate starts the edit.

Tips

• One change per edit works best. For two changes, edit the result again.
• Say what must stay, too. In a test on a selfie, Change her jacket to a red sweater. Keep her face and the background the same. changed only the clothing.
• An edit that comes back unchanged usually means the editing model declined the request. The provider still charges for it.
• In a test with the same picture and instruction, FLUX Kontext dev changed only the window frame. Qwen Image Edit Plus and P-Image Edit also darkened the sill below it.
• Repeated edits can slowly change a face. For a face that must stay true, edit the original picture again rather than an edit of an edit.
• Every editing model in the list starts with its safety checker off. Replicate's usage policy still applies.
• In Chat, a request such as make the last picture black and white makes the same kind of edit through a job card.
