Select Layers: Click and drag to highlight layers you want to merge in the Layers panel
When working with multiple layers in Sumo Paint, merging them can help simplify your project and make it easier to manage. The first step in this process is to select the layers you want to merge. To do this, navigate to the Layers panel, which is typically located on the right side of the interface. This panel displays all the layers in your project, allowing you to organize and manipulate them effectively. Once you’ve located the Layers panel, identify the specific layers you wish to combine. These could be adjacent layers or layers scattered throughout the panel, depending on your needs.
To select multiple layers, you’ll use the click-and-drag method. Start by clicking on the first layer you want to merge. Hold down your mouse button and drag the cursor downward (or upward) to highlight additional layers. As you drag, you’ll notice that the layers within the selected range become visually distinguished, often appearing shaded or highlighted. This visual feedback ensures you’ve correctly selected all the layers you intend to merge. If you make a mistake, simply release the mouse button and start again.
It’s important to note that the order of the layers matters when merging. The topmost selected layer will be the one that appears on top after the merge, while the layers below it will be combined underneath. Therefore, ensure the layers are arranged in the desired order before selecting them. If needed, rearrange the layers by clicking and dragging them to their correct positions in the Layers panel before proceeding with the selection.
If you need to select non-adjacent layers, hold down the Ctrl key (Windows) or Command key (Mac) while clicking on each layer individually. This method allows you to pick specific layers without having to merge all the layers in between. Once you’ve selected the desired layers using either the click-and-drag method or the individual selection method, you’re ready to proceed with the merging process.
After selecting the layers, take a moment to double-check your selection to ensure no unintended layers are included. Mistakes at this stage can lead to irreversible changes, as merging layers is a destructive action. Once you’re confident in your selection, you can move forward with the next steps to merge the layers, which typically involves right-clicking on one of the selected layers or using a specific merge function in the Layers panel menu. This careful selection process is crucial for achieving the desired outcome in your Sumo Paint project.

Merge Options: Use Merge Down to combine selected layer with the one below it
When working with layers in Sumo Paint, the Merge Down option is a straightforward and essential tool for combining layers. This feature allows you to merge the selected layer with the one directly below it, effectively reducing the number of layers in your project while preserving the content. To begin, ensure your project is open in Sumo Paint and that you have multiple layers visible in the Layers panel. Select the layer you wish to merge by clicking on it in the panel. The selected layer will be highlighted, indicating it is ready for modification.
Once the desired layer is selected, navigate to the Layer menu at the top of the interface. In the dropdown menu, you will find the Merge Options. Hover over or click on this option to reveal a submenu with various merging choices. Among these, the Merge Down option is specifically designed to combine the selected layer with the one immediately below it. Click on Merge Down to execute the command. Sumo Paint will instantly merge the two layers, creating a single layer that contains the combined content of both.
It’s important to note that Merge Down is a destructive action, meaning the original layers are permanently combined and cannot be separated afterward. Therefore, it’s advisable to save a copy of your project or duplicate the layers before merging, especially if you anticipate needing to edit them individually later. This precaution ensures you can revert to the original layered structure if necessary. Additionally, ensure the layers you intend to merge are properly aligned and positioned as desired, as their relative placement will be retained in the merged result.
The Merge Down function is particularly useful when simplifying complex compositions or when you no longer need to edit specific elements independently. For example, if you have a background layer and a foreground layer that are finalized, merging them can streamline your workflow and reduce file size. However, exercise caution when merging layers with transparency or blending modes, as these effects may interact differently once combined. Always preview the merged result to ensure it meets your expectations.
To summarize, using Merge Down in Sumo Paint is a simple yet powerful way to consolidate layers. By selecting the appropriate layer and choosing Merge Down from the Merge Options, you can efficiently combine it with the layer below. Remember to plan ahead, as this action is irreversible, and ensure your layers are prepared for merging. This technique is invaluable for cleaning up your layer stack and finalizing specific elements of your design. With practice, mastering Merge Down will enhance your ability to manage layers effectively in Sumo Paint.

Merge Visible: Merge all visible layers into one using the Merge Visible option
When working with multiple layers in Sumo Paint, you may find it necessary to combine certain layers into one for easier editing or to simplify your project. The Merge Visible option is a powerful tool that allows you to merge all visible layers into a single layer, while keeping hidden layers intact. This feature is particularly useful when you want to flatten specific elements of your design without affecting the entire composition. To begin, ensure that all the layers you wish to merge are visible in the Layers panel. You can toggle the visibility of individual layers by clicking the eye icon next to each layer name.
Once you have confirmed that the correct layers are visible, navigate to the Layer menu at the top of the Sumo Paint interface. In the dropdown menu, you will find the Merge Visible option. Clicking on it will instantly combine all visible layers into one new layer. This process is irreversible, so it’s a good practice to save your project beforehand or duplicate the layers you intend to merge, just in case you need to make adjustments later. The merged layer will appear at the top of the Layers panel, with its contents flattened into a single editable element.
It’s important to note that Merge Visible only affects layers that are currently visible. If there are hidden layers in your project, they will remain unchanged and separate from the newly merged layer. This distinction makes Merge Visible a more controlled alternative to the Merge Down or Merge All options, which combine layers based on their position or entirety, respectively. By using Merge Visible, you maintain flexibility in your workflow, as you can still edit or manipulate the hidden layers independently after merging the visible ones.
To optimize your use of Merge Visible, consider organizing your layers thoughtfully before applying the function. Group related elements on visible layers and keep unrelated or background elements on hidden layers if you don’t want them included in the merge. This approach ensures that your merged layer contains only the desired components, streamlining your editing process. Additionally, renaming layers before merging can help you identify the contents of the new merged layer more easily, especially in complex projects with numerous layers.
After executing Merge Visible, you can continue editing the merged layer as you would any other layer in Sumo Paint. Apply filters, adjust opacity, or add new elements directly to the merged layer. If you realize that you’ve merged layers prematurely or incorrectly, you can use the Undo function (Ctrl+Z or Cmd+Z) immediately after the merge to revert the action. However, once you’ve made additional changes or saved the project, reversing the merge will require manual separation of the elements, which can be time-consuming. Therefore, careful planning and layer management are key when using the Merge Visible option.

Flatten Image: Flatten all layers into a single background layer for simplicity
When working with multiple layers in Sumo Paint, you may find it necessary to simplify your project by merging all layers into a single background layer. This process, often referred to as "flattening" the image, is particularly useful when you want to reduce file complexity, save your work in a format that doesn't support layers, or simply finalize your design. To begin, ensure that all your layers are visible and arranged as desired, since flattening is a permanent action that cannot be easily undone.
To flatten your image in Sumo Paint, start by opening your project and navigating to the Layers panel, typically located on the right side of the interface. Here, you’ll see a list of all the layers in your composition. Before proceeding, double-check that each layer is positioned correctly and that any adjustments, such as opacity or blending modes, are finalized. Once you’re confident, look for the layer management options, usually represented by icons or a dropdown menu at the top of the Layers panel.
Among the options, you’ll find a function labeled "Merge Layers" or "Flatten Image." In Sumo Paint, this might be accessed through a specific icon or by right-clicking within the Layers panel. Selecting this option will prompt the software to combine all visible layers into one. If your project includes hidden layers, they will not be included in the flattened result, so ensure all necessary layers are visible beforehand. After confirming the action, Sumo Paint will merge the layers, leaving you with a single background layer containing all your combined elements.
Flattening an image is irreversible, so it’s a good practice to save a copy of your project with layers intact before proceeding. This way, you can always return to the layered version if needed. Once flattened, the image becomes much simpler to manage, especially for tasks like exporting or sharing. Keep in mind that while flattening reduces complexity, it also eliminates the ability to edit individual elements separately, so use this feature judiciously.
After flattening, you may notice a change in file size or performance, as the image no longer carries the overhead of multiple layers. This can be particularly beneficial when working with limited system resources or preparing files for web use. To finalize your flattened image, you can proceed with additional edits, such as adding filters or text, directly on the single background layer. Always remember to save your work in the appropriate format, such as JPEG or PNG, depending on your needs.
In summary, flattening all layers into a single background layer in Sumo Paint is a straightforward process that simplifies your project and prepares it for final use. By carefully reviewing your layers, using the appropriate merge function, and saving a backup of your layered file, you can ensure a smooth transition to a flattened image. This technique is essential for streamlining your workflow and optimizing your designs for various applications.
