Image Editing Masterclass

Master inpainting, outpainting, and advanced editing techniques


LetzAI's editing tools give you powerful control over your images. Whether you want to change small details or completely transform a scene, this guide covers everything you need to know.


Understanding the Edit Tab

The Edit tab is where you'll find all of LetzAI's image modification tools. You can edit any image - whether generated by AI or uploaded from your device.



Editing Images with Natural Language

Modern image editing models can understand natural language instructions. Instead of manually selecting areas or using technical tools, you simply describe what you want to change.

You can use editing to:

  • Change small details (colors, text, objects)
  • Replace or remove elements
  • Adjust lighting, mood, or time of day
  • Transform the overall style of an image
  • Add completely new elements to the scene

In many cases, a clear sentence is enough for the AI to understand the requested change.

How editing typically works

  1. Upload or select the image you want to edit in the Edit tab
  2. Describe the change you want in plain language
  3. Generate the result and iterate if needed

Basic tips for better edits

  • Be specific: Clear instructions lead to more predictable results
  • Change one thing at a time: Smaller edits are easier to control
  • Iterate: Generating multiple versions helps you reach the best result


Guided Creation for Precise Edits

Sometimes a written prompt alone is not enough — especially when changes need to happen in a specific area of the image. This is where Guided Creation comes in.

Guided Creation adds a visual layer on top of your prompt. You can draw, add shapes, arrows, or write notes directly on the image to show the AI exactly what should be changed and where.

This is especially helpful when:

  • Editing text or logos
  • Changing specific objects
  • Replacing backgrounds
  • Making targeted adjustments without affecting the rest of the image

How it works

  1. Open your image in the Edit tab
  2. Activate Guided Creation
  3. Draw or write directly on the image to highlight the change
  4. Describe the edit in your prompt and generate the result

By combining visual guidance with natural language instructions, Guided Creation makes edits more precise and predictable.



Extend Your Canvas

You can extend an image beyond its original borders by guiding the AI to expand the scene naturally.

Unlike older workflows, you no longer manually select how many pixels to extend in a specific direction. Instead, you use natural language instructions and, if needed, a new aspect ratio to define the expanded composition.

How to extend an image

Option 1: Describe the expansion

Use a prompt such as:

  • "Zoom out of the image and extend the scene toward the left, revealing more of the environment"
  • "Widen the frame and show more of the landscape on both sides"
  • "Expand the background upward to include more sky"

The model will reinterpret the scene and generate a larger composition that blends with the original image.

Option 2: Change the aspect ratio

Select a new aspect ratio (for example, from square to 16:9 or 9:16) and prompt the AI to adapt the image into the new format.

Example:

  • "Extend the scene naturally to fill the new vertical format"
  • "Keep the subject centered and expand the environment around them"

The AI will place the original image into the new canvas and generate additional content to fill the space.



Background Removal and Replacement

You can remove or replace the background of an image using simple instructions.

Examples:

  • "Remove the background and place the subject in a modern office"
  • "Replace the background with a tropical beach"
  • "Change the background to a clean studio backdrop"

For more precise results, Guided Creation can be used to highlight the subject or the area that should be replaced.



Style Transfer

You can transform the overall visual style of an image while keeping the main content.

Examples:

  • "Make this look like a cinematic movie still"
  • "Turn this into a watercolor painting"
  • "Convert the image into a vintage film photograph"

Style changes can be subtle or dramatic, depending on how clearly you describe the desired look.



Advanced Techniques

Iterative Editing

Image editing is often a creative, step-by-step process. Instead of trying to achieve the perfect result in one prompt, it's normal to refine your image across multiple edits.

Example workflow:

  1. "Replace the background with a beach"
  2. "Make the lighting warmer and more cinematic"
  3. "Add subtle wind movement to the hair"
  4. "Increase contrast and color depth"

Breaking edits into smaller steps gives the AI clearer instructions and leads to more consistent results.

Combining Enhancement Techniques

You can combine multiple features to progressively improve and expand your creations.

A common creative workflow might look like this:

  1. Edit and refine details in your image
  2. Extend the scene or adapt it to a new format
  3. Generate additional variations or follow-up scenes
  4. Upscale the final result for maximum quality
  5. Animate the image to turn it into a video

Using these features together helps you move from a simple image to a polished, fully developed piece of content.

Using Reference Images

When available, upload reference images to guide the AI's edits. This helps achieve specific styles, poses, or compositions.



Common Editing Scenarios

Changing Clothing

  1. Select the clothing area with Guided Creation tool or by explaining the changes with natural language texts
  2. Describe the new clothing in detail (color, style, material)
  3. Generate and refine as needed

Adding or Removing Objects

  • Adding: Select the area and describe what you want to add
  • Removing: Select the object and describe what should replace it (or just "background")

High-Resolution Refinement

You can also use the Edit workflow to improve the overall quality of an image while keeping its original look.

To do this:

  1. Open the image in the Edit tab
  2. Set the output resolution to a higher size (for example, 4K)
  3. Use a prompt such as:
  • "Resharpen and upscale this image while maintaining the original likeness"
  • "Increase detail and clarity without changing the composition"
  • "Enhance texture and sharpness, keep everything else the same"


Quality Tips

  • Work at high resolution: Edit high-quality images for best results
  • Match lighting and shadows: Your prompts should consider the existing light direction
  • Be patient: Complex edits may require multiple iterations


Using Chat for Editing

Editing with LetzAI Chat

You can also edit images directly inside LetzAI Chat using conversational instructions.

Instead of switching tools, you can simply describe what you want to change and refine the result through back-and-forth messages.

Examples:

  • "Make the colors warmer and more vibrant"
  • "Change the background to a snowy landscape"
  • "Remove the object on the table"
  • "Make the lighting look like sunset"

Chat is especially useful for quick adjustments, experimentation, and iterative changes.

For more precise or complex edits — especially when specific areas must be targeted — the Edit tab with Guided Creation provides more control.
