Canvas Editor is a powerful image editing tool that allows you to make intricate adjustments to your images, remove unwanted elements, or even generate new content using advanced inpainting and outpainting techniques.

With the release of Canvas Editor, you now have full granular control to alter, tweak and refine your images in powerful and distinct ways. In this guide, we will walk you through all the various aspects of Canvas Editor, including the new and updated features and tools, so that you can take full advantage of this powerful editing suite.

Now that you're familiar with the great new features of Canvas Editor, it's time to start using it. Let's dive into how it all works.

Upload Image:

To begin using Canvas Editor you need to upload an image. To do so, simply:

  1. Click on ‘Upload Image’ button on the lefthand toolbar

  2. Choose an image. (Either one stored on your computer, a previous generation or one from the Community Feed)

  3. The image will appear on the canvas, and then you’re ready to get started!

Selecting / Moving and Shortcutting

To move elements around on the canvas, including the generation frame and any new images you generate, use the 'Select' (arrow) tool. (Important note: Canvas Editor will only generate within the generation frame, and when the lock on its upper left corner is open).

  1. Click on the 'Select' button on the toolbar and then click on the element you want to move.

    You can then drag and drop the element to the desired location.

  2. You can use Pan to navigate around the actual canvas itself

  3. You can also Zoom using the '+' button to zoom in and the '-' button to zoom out. (You can also scroll on your mouse or trackpad to zoom in and out). In addition, you can select one of the several preset zoom levels with the zoom level indicator next to the + - buttons.

  4. Lastly, the keyboard button at the top of the screen is the Keyboard Commands Shortcut, which provides both PC and Mac hotkeys for easier navigation and use.

Drawing a Mask or Erasing an Image

You can easily modify your images effectively using the 'Draw Mask' or 'Erase' buttons on the toolbar.

  • Masking an area retains some of the subject and style underneath, making it ideal for minor touch-ups.

  • Erasing an area completely removes unwanted parts or prepares for replacement

Once your desired changes have been made, you can simply enter a prompt in the text bar at the base of the screen to regenerate the area within the generation frame.

Detailed Breakdown:

Draw Mask

Once selected, use the pointer to paint a mask over areas of an image you want to change or finesse. Once you have masked an area, you can enter a prompt for the image, such as "person wearing sunglasses," and regenerate the masked area. This feature allows you to make specific changes to your image without affecting the rest of the picture while also retaining some information of the image under the mask such as colour, subject and style.


Once selected use the pointer to highlight an area to erase. After you can enter a prompt for the image and regenerate the erased area. This feature is useful when you want to get rid of an unwanted element in your picture, as well as an alternative to masking if the changes you are trying to make are too heavily influenced by the original image underneath.

Note that you can select between the different erasing modes: All, Images, Sketches or Mask to determine what gets erased.

Download Artwork

Once you've created an image you're happy with, click on the 'Download Artwork' button on the toolbar to save the image to your computer.

Undo & Redo

If you make a mistake or want to undo an action, use the 'Undo' and 'Redo' buttons on the bottom-left of the canvas.

Focus Mode

Focus Mode is an much more simplified take on inpainting. With Focus Mode, simply select an area where you would like to inpaint with the lasso tool, prompt and then generate.

To enter Focus Mode, select an image with the Selection Tool and then simply click on the Focus Mode button in the top right corner of the canvas.

To return to the default mode of the Canvas Editor, just click on Infinite Mode.
(Note: You may be required to accept or cancel any pending changes beforehand)

Focus Mode Settings

  • Finetuned Model: Select your preferred finetuned model. The closer the finetuned model is to your image's style, the easier it is to get results that look integrated within the image.

  • Inpaint Strength: Adjusting the Inpaint Strength affects how much the underlaying image is taken into account when inpainting. Higher values may result in better prompt adherence but will ignore the lighting and style of the original image. An amount is between 0.7-0.9 is advised

  • Number of Images: The amount of variations that will be generated. Please do note that this affects the token cost.

  • Advanced Settings: An fixed seed option is available where you may enter an seed value to be utilized. For Premium users, there is also an option to select the Scheduler type to be used for generating.

Using the Control Panel

The 'Control Panel' on the right-hand side of the canvas is the main area where you can access the various tools to fuel your editing efforts. These include:

  1. Model: The base model you will use to edit your image. (It is a good idea to use the same model you created the original image with where possible)

  2. Canvas Mode: Where you can select the various new and upgraded modes to use, such as Sketch2Img

  3. Outpaint: Having this on will ensure that levels are set to work well with outpainting options - which are broader than those of Inpainting. ****(Toggling this option [on] disables Input Strength)

  4. Inpaint Input Strength: Adjusts how closely the new generation will follow the underlying image

  5. Number of Images: This is how many alternate regenerations the model will create, which you can scroll through using the arrow buttons to see any which works best (or cancel and retry if none do)

  6. Image Dimensions: Allows you to alter the resolution of the generated content (of particular note when generating larger areas)

  7. Render Density: Decreases the size and increases the pixel density of the generation context

  8. Guidance Scale: How strongly your text prompt is weighted. (It is tempting to go high here, but this can actually create issues – we recommend 7-9)

  9. Advanced Settings: Here you can enter an seed, set it to fixed (constant) or change the Scheduler used (Only for users on an subscription plan).

Prompting & Generating

To generate new content, enter your prompt in the 'Prompt' text field and click on the 'Generate' button. Tips for entering a good prompt: be specific, use complete sentences, and describe all of the elements you want to include in the generated frame. You can also use the 'Negative Prompt' button to tell the AI model what not to generate, such as ‘extra limbs’ and ‘nudity.’


When selected, you will be able to prompt as if you were in the standard Image Generation section of the platform - albeit with slightly more streamlined functionality designed for optimal Canvas performance. Simply use the prompt option at the bottom of the screen to create a fresh image (that ignores the previous context) within the generation field box.


To use this tool, choose it from the Canvas mode selection area and then move the generation field box to the desired location. From here you can re-prompt using the input field at the bottom of the screen.

Depending on the size of the generation box, the prompt clarity – and its weighting – the changes can be subtle or major, allowing for an incredibly vast array of regeneration options that can totally transform your images, or enhance them in slight, yet meaningful ways.


To use this handy new feature, select Sketch2Image from the Canvas mode area, move the generation box to the desired area and then select the sketch icon from the left-hand toolbar. A new floating toolbar will appear with colour and sketch size options. For the most effective results try and be accurate with the colours, rough shape, size and position of what you want, coupled with good prompts.

I.E., Use something like green colouring for a dragon and orange for its fire breath, in a position that shows its wings, feet and tail at an accurate scale compared to its distance and position in relation to other objects.


Inpainting in Canvas Editor effectively allows you to select specific areas of a base image and then use our advanced tools to first prompt and then fill in unwanted, missing, or corrupted parts in order to produce the desired result.

To use it, select Inpainting / Outpainting from the Canvas mode area of the right-hand toolbar. Once selected, use the generation box to highlight the area you wish to regenerate, make sure the lock is open (to allow editing) and use the mask tool to highlight the area you want to regenerate. Then simply type your desired prompt into the generation field. (Remember that the Inpaint strength will alter how adherent to the underlying image the new version is). You can cycle through the different options if you selected more than one image to select which works best.

Note - if you aren’t getting any notable results from input, the underlying image might be too strong. In this case, it might be necessary to use the erase. In addition, upscaled images can be tricky to edit, so it is worth using an original version of the image and upscaling later.


Outpainting, allows you to generate a coherent extension of your base image beyond its original boundaries. When done correctly the Canvas Editor will expand the scene in a way that seamlessly aligns with the original image content.

To use it, select Inpainting / Outpainting from the Canvas mode area of the right-hand toolbar. Once selected, use the generation box to highlight an area beyond the edge of the base image (while keeping enough of the original in for style comprehension - around 60/40 is a good ratio). Remember the Outpainting strength will also dictate how faithful to the original image the new generation is.

And that will do it for the Canvas Editor guide - we hope you found it useful! Remember, we are always adding new features and enhancing old ones, so be sure to check back in here from time to time to check for updates.

Happy Prompting! 🎨
