Performing AI Edits on Images

Use this guide when an image is mostly right, but the image content itself needs to change.

Written by Erika

Quick edit is Riverflow's AI image editing workflow. It changes the pixels in an image from a written instruction. Use it for local visual changes, product-safe retouching, background changes, object removal, prop replacement, lighting adjustments, and other edits where Riverflow needs to regenerate part of the image.

For precise edits like removals, object sizing, location changes, use the Mask Tool as part of the Quick Edit. All Riverflow subscribers can use Mask-based editing.

If you want to move text, logos, images, or other visible layers yourself, see Using Canvas Editor for Images instead.

When To Use Quick Edit

Use Quick edit when:

  • the image is already close to what you need

  • one area or detail needs to change

  • the change can be described clearly in words

  • the image itself needs to be regenerated or repaired

  • you can add a reference image for anything that must match closely

Quick Edit is useful for tasks such as:

  • removing an unwanted object

  • replacing a prop

  • changing a background detail

  • adjusting lighting or colour tone

  • cleaning up a product detail

  • changing product artwork

  • improving how a product sits in a scene

  • making a masked edit to one part of the image

If the whole image is wrong, use Generate again, See more like this, or Remix where available. If the scene is right but the product should change, use Swap products. If the main issue is product label, logo, artwork, packaging, or visible text accuracy, use Fix product details.

Open Quick Edit

  1. Open the image you want to edit.

  2. Choose Quick edit.

  3. Write a clear instruction for the change you want.

  4. Add reference images if they help explain the change.

  5. Use a mask if only one part of the image should change.

  6. Choose the model, aspect ratio, resolution, and output count shown in the edit panel.

  7. Generate the edit.

  8. Open the result and choose the next action.

Quick Edit creates a new result. The original image remains available.

Write A Good Edit Prompt

The Quick Edit prompt box is not a chat. Treat each edit as a fresh visual instruction for an AI image-editing model.

A strong edit prompt says:

  1. what should change

  2. what should stay the same

  3. how each reference image should be used

  4. what Riverflow should not change

Use this structure:

Change only [specific area or object] to [desired result]. Preserve [important parts of the image that should not change]. Use the attached reference image for [specific detail] only. Do not change [anything important to protect].

Avoid vague instructions such as make it better, fix the product, or make it premium. Rewrite them as specific visual changes.

Prompt Examples

Make A Small Visual Change

Make the lighting warmer and softer. Preserve the product, camera angle, composition, background, and all visible text.

Remove An Object

Remove the cup from the selected area. Fill the background naturally so it matches the surrounding table surface, lighting, and shadows. Do not change the product or the rest of the scene.

Replace A Prop

In the selected area, replace the orange slices with sliced pear. Match the existing camera angle, lighting, shadows, and image style. Do not change the product, label, background, or composition.

Match A Product Reference

Change only the product to match the attached product reference. Preserve the current scene, camera angle, lighting, shadows, and product position. Keep the product shape, proportions, label placement, colours, material finish, logo, and visible text faithful to the reference. Do not copy the reference image background.

Correct Product Text Or Label Details

Change only the product text and label details that are incorrect. Preserve the product geometry, proportions, cap shape, camera angle, lighting, shadows, label boundaries, material finish, and background. Replace the visible product text with exactly: "[insert exact text]". Do not redesign the product or change the scene.

Use References Clearly

Reference images work best when you give each one a clear job.

Quick Edit does not know what you mean by my product, the original, or the reference unless you attach the relevant image and explain how it should be used.

Use reference images for details such as:

  • product shape and proportions

  • label or artwork details

  • logo placement

  • material finish

  • prop appearance

  • human appearance or styling

  • lighting or mood

  • texture or surface detail

A good reference image is sharp, well lit, focused on the detail you want to match, and not crowded with unrelated objects.

If you attach more than one reference image, give each one a job.

Example:

Use image 1 as the base image.
Use image 2 as the product reference for shape, label placement, colour, logo, and material finish.
Use image 3 for lighting style only.
Do not copy the background or props from image 3.

Use Masking For Local Changes

Masking tells Riverflow which part of the image to edit.

Use masking when only one area should change, such as a label, prop, hand, background mark, or product detail.

  1. Open the image.

  2. Choose Quick edit.

  3. Use the on-image masking toolbar to paint or select the area you want to change.

  4. Write the edit instruction in the prompt box.

  5. Add reference images if needed.

  6. Generate.

  7. Open the result and choose the next action.

Mask the full area that needs to change. If you are replacing an object, cover the object and a small margin around it so the new result can blend with the lighting, edges, and shadows.

Masking helps Riverflow focus the edit, but it is not a pixel-perfect selection tool. For exact object placement, exact typography, or precise design layout, use the canvas editor or a clearer source asset rather than trying many prompt-only edits.

If you do not draw a mask, Riverflow treats the instruction as a whole-image edit.

Choose An Edit Model

If the edit panel shows a model selector, choose the model based on how much accuracy the edit needs.

For product identity, labels, logos, visible text, detailed references, and difficult masked edits, use a higher-quality Riverflow model (either Riverflow 2.5 Pro - High or Riverflow 2.5 Pro - XHigh).

For softer stylistic edits, such as lighting, colour tone, mood, or atmosphere, a faster cheaper model may be enough.

Model availability can vary by workspace. If the first result drifts, simplify the prompt, improve the reference, tighten the mask, or try a higher-quality model where available.

What To Avoid

Avoid chat-style feedback such as:

No, that is still wrong. Try again and make it more like the photo.

Rewrite the request as a fresh image-edit prompt instead.

Avoid stacking too many edits into one prompt. If you ask Riverflow to change the product, background, props, lighting, crop, text, and hand position all at once, the edit is more likely to drift.

Work in smaller steps:

  1. fix the most important issue first

  2. choose the best result

  3. make the next edit from that result

Avoid relying on prompt-only edits for highly precise layout changes, such as exact object placement, complex text layout, or layered design work. Use Editor when the layout itself needs manual control.

Quick Edit Checklist

Before you generate an edit, check:

  • have you said exactly what should change?

  • have you said what should stay the same?

  • did you attach the right reference image?

  • did you explain what each reference image should be used for?

  • if using a mask, did you cover the full area that needs to change?

  • are you asking for one main edit, rather than several changes at once?

  • would Fix product details, Swap products, Generate again, See more like this, or Remix be a better next step?
