Roblox Decals and Image ID Guide

Roblox decals allow players to customize game worlds by applying user-uploaded images onto surfaces. In Roblox, every decal or image you upload is given a unique ID code – a numeric key you can use in scripts or the toolbox. These image IDs make it easy to share custom graphics in-game. For example, “Image IDs allow you and everyone else in Roblox to share images that have been uploaded to the game simply by using unique codes”. In practice, a single decal attaches one of these images to a part or union’s face in the game. This guide explains what decals and image IDs are, how to find and use them, and best practices for uploading your own art on Roblox.

Example of a user-created Roblox decal (anime-style art). Users upload images like this as decals, each with its own image ID to apply onto game parts.

What Are Roblox Decals and Image IDs?

A Roblox Decal is a game asset that applies an image to a single face of a 3D object (a BasePart). In code, the Decal object’s Texture or Image property holds the asset ID of the image.

As one Roblox developer explains, “Decal is an object which applies an image to a face of a BasePart”. In contrast, a Texture object can fill or tile across entire surfaces. In everyday use, though, players find decals in the Creator Marketplace and think of them as shareable images. Roblox itself notes that “Decals are an asset type and a category on the Creator Marketplace. Each decal represents a decal with a linked image”. In other words, every decal you browse in the library corresponds to an underlying image asset.

Each uploaded image (through the Decal process) gets two IDs: a Decal ID (the catalog item) and an Image ID (the raw image). In practice these often appear interchangeable. What matters is the unique Roblox ID number: this code – e.g. 537570361 – tells the engine which image to use. These IDs can be placed in scripts or the Toolbox to apply that image. In short, decals are the common way to upload and apply custom images in Roblox. According to the Roblox Wiki, “Decals are the most common way to upload images to be used in other graphical elements” like UI or skyboxes.

Roblox image IDs are widely used. When you place a decal in a game or GUI (like an ImageLabel), you assign an ID such as rbxassetid://12345678 to that part’s Image or Texture property. Essentially, that code points to the user-uploaded image on Roblox’s servers. Community sites maintain huge lists of these codes. For example, Roblox Den lists thousands of decal IDs and notes they can “be used in games… to customize your game”. In other words, any picture you upload (meme, art, logo, etc.) becomes a decal with its own image ID.

Key points about decals and images:

• Decals are user-uploaded images applied to parts; textures can fill larger areas, but decals stick to one side.
• Uploaded images are restricted to JPEG, PNG, TGA, BMP formats. Roblox supports these four formats when creating a decal asset.
• Any uploaded decal is moderated and resized. Roblox automatically “downscale[s] it to 1024×1024” pixels maximum to save on performance. This means high-res uploads get scaled down.
• Community Standards apply: images with disallowed content (nudity, hate symbols, copyrighted images without permission, etc.) are blocked. Only family-friendly, original or licensed images should be used.

In summary, decals are how you turn any image into a Roblox asset, and each gets an image ID code that identifies it uniquely in games.

Finding and Using Image IDs in Roblox

Browsing Decals in the Catalog

The Roblox Creator Marketplace (formerly Creator Store or Catalog) is where you find decals and other assets. Under the store’s Images or Decal section, thousands of user-made pictures are available (mostly free). Note that images are an asset type, but they don’t appear directly when you search “Images.” Instead, you browse Decals (Images) as a category. As the Roblox Wiki explains: “Images are not a category and cannot be searched… However, the decal category is the primary way of finding images”.

To browse decals: go to Create > Store (or Catalog) > Images (Decals) on the Roblox website or in Studio. You can filter by category (Memes, Anime, Aesthetic, etc.), tag, or search keyword. When you find an image you like, click it and hit Get Decal to add it to your inventory. Internally, this saves the asset and its ID to your account. Later, when you insert a Decal object onto a part, you can choose from your inventory, or directly paste an ID code.

Pro tip: Community databases list popular image IDs. For example, Roblox Den’s searchable index lets you filter by tag (Meme, Anime, etc.) and copy IDs. Many players use these sites to find fun decals (cats, cartoons, quotes) and grab their IDs without uploading themselves. Keep in mind these IDs must be for publicly available images in Roblox.

Copying and Using Decal IDs:

Once a decal is in your account or game, you need its ID to apply it. Here are common methods:

• Toolbox / Studio: In Roblox Studio, the toolbox allows copying an image ID from any decal you find. When you click “Get Decal,” an ID is stored. If you insert a Decal in Studio and look in the Properties panel, the Texture (or Image) field shows a URL like rbxassetid://12345678. You can copy that number. The official Wiki notes: “placing [the decal] in Roblox Studio will reveal the image ID… The toolbox also allows copying an image ID from a decal”.
• URL Method: If you have the Decal’s catalog page URL, it often contains the asset ID. You can also find the ID by subtracting 1 from the URL ID (an older trick) or by inserting the asset in Studio. Some plugins (like BTRoblox) even provide buttons to directly navigate to the image variant and get its ID.
• Scripts: In-game, you can use rbxassetid:// URIs. For example, in a script:

• local decal = Instance.new(“Decal”, workspace.Part)
• Texture = “rbxassetid://12345678” — where 12345678 is the image ID

• Many developers simply paste the numeric ID (with the rbxassetid:// prefix) into Decal.Texture or an ImageLabel’s Image property. This tells Roblox to fetch that image from its servers.

Once you have the ID, you can share it. Typing rbxassetid:// followed by the number into any Decal, Texture, or GUI Image property will display that picture in-game. For example, one player says when you “grab the ID from the URL [and] paste it into the decal or texture field in Studio”, it automatically works.

Using Decals In-Game:

To use a decal image in your game:

• Insert a Decal object into a part (in Studio or via script) and set its Texture to the image ID (as above). The image will appear on that face.
• For textures or SpecialMeshes, assign the Texture or MeshId similarly (these also use rbxassetid://).
• For UI images (ImageLabel, ImageButton), set the Image property to rbxassetid://ID. This lets you use any decal image as a GUI element or icon.

Example: If you have an image ID 12345678, you could in Studio set a Brick’s SurfaceGui > ImageLabel.Image to “rbxassetid://12345678”. That GUI would show your chosen image.

Roblox automatically handles the difference between a decal’s content ID and image ID. In fact, scripts often use the image ID form for direct referencing. According to the developer forum, “Studio automatically converts” the decal asset ID to the image ID when you paste it into a property. So generally, you can use the ID found on the asset page, or use the rbxassetid:// format interchangeably.

Creating and Uploading Your Own Decals:

To upload a custom image to Roblox as a decal, follow Roblox’s creation process:

1. Prepare your image file. Make sure it’s appropriate and follows Roblox’s rules (no copyrighted art, no explicit or hateful content). Save it as JPEG, PNG, TGA, or BMP. Note the size: Roblox will shrink anything above 1024×1024 pixels. Using exactly 1024×1024 is safe to maximize detail.
2. Go to Creator Dashboard – Decals. On the Roblox website, click Create and choose Decals under Development. (In the newer Creator Dashboard, it’s Creator Dashboard > Creations > Decals).
3. Upload the image. Drag and drop your file or click Upload Asset. When you submit, Roblox will automatically create an underlying Image asset and a linked Decal asset. The image is then sent for moderation.
4. Wait for review. Uploaded decals are moderated and reviewed before they are displayed. This can take minutes to hours. You cannot use the decal in-game until it’s approved. Once approved, it appears in your inventory and the catalog for others.
5. Get the ID. After approval, click on your newly created Decal in the dashboard to view its page. The URL or properties panel will show its asset ID. Copy that number; this is your decal’s ID to use in games. (Alternatively, insert the decal in Studio and copy the ID from its Texture property.)

Roblox’s official guides confirm this flow: “To create a decal, you have to add a Decal object to a part or union. You can import images for decals to Studio… dragging or uploading an image file. Roblox supports JPEG, PNG, TGA and BMP.”. Remember: once an image is uploaded, Roblox moderates it. If it violates community rules, it will be rejected. If approved, you now have a unique ID for your custom art to use anywhere.

Tips for Uploads:

• Keep it clear. Decal images appear on game parts; high detail or small text might not show well.
• Mind the background. Transparent PNGs let a decal blend into the part; JPEG backgrounds may be visible as a border.
• Check Roblox rules. Don’t upload anything copyrighted, offensive, or breach the Roblox Terms of Use. The DevForum warns that all uploaded images are filtered, and “content that you do not own or have permission to use” will be removed.

Roblox Catalog and Marketplace Features:

The Creator Marketplace (a.k.a. Creator Store) organizes user assets by category. Its Images section is essentially the decals library. Roblox Support notes that the Creator Store includes images, meshes, audio, fonts and more. In practice, when browsing, “Decal” or “Images” is the category to find user-submitted graphics. You can filter by genre (Funny, Aesthetic, etc.) or search by tag.

Inside Studio, the Toolbox mirrors this: it has a tab for decals (images). You can search by keyword directly in Studio’s toolbox or go to the web catalog. When you find a decal asset, you can click it to add it into the current place (parenting it to any selected part). This is an easy way to place any image into a scene without manually inserting and setting IDs.

In addition to Roblox’s official catalog, several third-party databases help you find image IDs. Sites like RobloxDen index thousands of IDs by theme. You might see categories like Anime Decals, Meme Decals, or Cursed Images. When using such IDs, be sure they link to legal, public images.

Difference: Decals vs Textures vs Meshes:

While the term “texture” is often used casually, in Roblox there is a distinction:

• Decal: A single image applied to one face of a part or union. It does not tile or repeat. Use decals when you want one picture on one side (e.g., a logo on a wall).
• Texture (object): A tiling image that covers an entire part surface, usually repeating in a grid. Useful for patterns like brick walls, grass, or flooring.
• SpecialMesh: In some cases, a mesh has a TextureId property for one image applied to the whole mesh.

For example, a shirt or poster could be a decal on a part, whereas a ground could use a Texture for a repeating pattern. Both types ultimately reference image IDs. Decals and Textures share similar workflow (set the Texture property to rbxassetid://ID). The key difference is in how they render: decals stick and can stretch, textures tile across.

Best Practices & Tips:

• Use LSI keywords: In this context, incorporate related terms naturally. For instance, think of Roblox catalog when searching decals, or Roblox art when discussing creative decal designs.
• Optimize images: Compress PNGs or JPEGs before uploading to reduce load time (Roblox will still resize, but smaller file size helps). Give descriptive filenames before upload (e.g. galaxy-sky-decal.jpg).
• Attribution: Only use images you created or have rights to. Roblox will remove copyrighted art.
• Community etiquette: Share codes responsibly. If you post image IDs online, mention what the image shows (e.g., “sunset landscape decal”). This helps others know what they’re using.
• Engagement: Have questions about a particular decal? Or your own creation to show off? Drop a comment or join Roblox developer forums/Discord groups. Many creators love feedback on their Roblox art.

Frequently Asked Questions:

Q1: How do I find a decal’s image ID on Roblox?
A: The simplest way is via Roblox Studio’s Toolbox. Find the decal asset (in Toolbox > Marketplace > Images) and click it. The ID appears in the tooltip or the Texture property. You can also place the decal in a part and read its Texture property. Alternatively, copy the number from the decal’s catalog URL. The Roblox Wiki confirms that inserting the asset in Studio “will reveal the image ID through the object’s property”.

Q2: What’s the difference between a decal ID and an image ID?
A: Technically, the decal ID is the asset in the catalog, while the image ID is the underlying image file’s ID. But for use in games, both act similarly. If you have a decal’s asset ID, Roblox Studio automatically uses its image ID when you set the Texture property. In practice, you can paste either (often via rbxassetid://) and Roblox fetches the right image.

Q3: How do I upload my own decal?
A: Go to Create > Decals on the Roblox website. Upload your image file (JPEG/PNG/etc.). Roblox will convert it into a decal (moderated first). Once approved, view the decal page to get its new ID. For detailed steps, see the Roblox Support article “How to Make Decals.”

Q4: What formats and sizes are allowed for Roblox decals?
A: Supported formats: JPEG, PNG, TGA, BMP. Max resolution is effectively 1024×1024 pixels – anything larger is automatically downscaled. If you upload a 2K image, Roblox will shrink it to 1K. There’s no explicit file-size limit (Roblox will handle it by resizing). Using 1024×1024 with good compression (especially JPEG) is recommended.

Q5: Can I use any image as a decal in my game?
A: Only images that comply with Roblox’s Community Standards and copyright rules. Do not use copyrighted logos, brand images, or any adult/hate imagery. Roblox actively scans uploaded images; as one policy note states, “Do not create or upload any images… that you do not own or have permission from the owner to use”. If your image violates rules, it will be rejected or removed. Always ensure you have rights to any art you upload.

Q6: Where can I find cool decal codes or ideas?
A: Check the Roblox Creator Marketplace under Images/Decals – many popular uploads (like memes or scenic art) are there. You can also visit fan sites or forums; for example, Roblox Den lists thousands of decal IDs by theme. Gaming blogs (like Radio Times) even list top decal IDs to try. Always use IDs from reputable sources to avoid copyrighted content.

Q7: How do I apply a decal to my game objects?
A: In Studio, insert a Decal object into the part you want, then paste the image ID into its Texture field (prefixed by rbxassetid://). The image will appear on that face. For GUI elements (ImageLabel, etc.), set the Image property to the same ID format. You can also script it.
