Make a Roblox Classic Shirt in your browser
This Roblox shirt maker provides a fixed 585 × 559 pixel canvas for preparing a Classic Shirt image without creating an account or sending artwork to a server. Start with transparency, fill the complete canvas with a color, or upload an existing template or design as a base. Choose a color and brush width to add details, switch to the eraser for transparent areas, undo recent changes, and download the current canvas as a PNG.
The editor is intentionally direct. It does not publish an asset, connect to a Roblox account, predict moderation, or pretend that a flat image is already wearable. It creates an image file at the standard full-canvas dimensions used by the current official Classic Shirt template. You can then inspect the placement, test it on a Block Avatar rig in Roblox Studio, revise seams, and follow the platform’s current upload process.
Why the canvas is exactly 585 × 559
Classic Shirts are wraparound clothing textures. The current template package linked from the Roblox Creator Hub Classic Clothing documentation uses a 585 × 559 PNG for the complete Shirt layout. Different rectangles within that canvas represent the front, back, top, bottom, left, and right surfaces of the torso and arms.
The output dimensions matter because those mapped regions depend on exact pixel positions. A generic square drawing, a screenshot of a template, or a file resized by a chat application will not preserve the expected layout. This maker keeps the underlying canvas at 585 × 559 during every operation and produces a PNG with those same decoded dimensions. The on-screen version can shrink responsively to fit a phone or laptop, but the saved image does not become smaller.
Correct dimensions are only the first requirement. A blank 585 × 559 file is technically the right size but contains no wearable design. Artwork placed outside mapped body panels may never appear. A front graphic drawn over a sleeve region will wrap around an arm instead of the torso. Always combine the dimension-safe canvas with the official mapping guide and an in-Studio test.
How to use the Roblox shirt maker
Begin on the transparent canvas when you want to draw from scratch. Choose a color, select the brush, and pick a width. Small widths are useful for seams, outlines, lettering, and pixel-level corrections. Larger widths cover broad areas quickly. Pointer input works with a mouse, pen, or touch device, although a larger screen and precise pointer are easier for detailed template work.
Use Fill canvas with color when the whole image should begin with one background color. Fill covers the complete rectangular PNG, including space that may not map to the avatar. If you need transparency around mapped panels, clear the canvas and paint only the required template regions instead. The eraser uses real alpha transparency rather than painting with white, so erased pixels remain transparent in the downloaded PNG.
The upload option accepts PNG, JPG, and WebP base images up to the local safety limit. An imported image is scaled proportionally to fit inside 585 × 559 and centered without cropping. This behavior is convenient for bringing in an existing template or sketch, but it cannot repair incorrect UV placement automatically. For accurate Shirt creation, upload a native-size official template or a correctly aligned working file.
Undo restores the state immediately before the latest brush stroke, erase stroke, fill, clear, reset, or import action. A limited in-memory history protects browser performance. Reset returns to the most recently imported base image; if no image was imported, it returns to the original transparent canvas. Download creates a PNG immediately from the current editor state.
Uploading a template versus a finished design
Uploading an official template gives you visible guides for body surfaces. Draw on a separate conceptual layer by avoiding guide labels and remove guides before the final export if they are not meant to appear. This lightweight browser tool uses a single flattened canvas rather than a multi-layer design document, so every imported pixel becomes part of the working image. Keep an original template file available in case you need to restart.
Uploading a finished or nearly finished 585 × 559 design is useful for corrections. You can erase unwanted marks, patch a small area, add a logo, or replace the full background color. Because an exact-size image already matches the canvas, it is drawn at native dimensions. Smaller or differently shaped files are fitted, which may not preserve intended template coordinates.
JPG images have no normal alpha transparency and can introduce compression artifacts around hard edges. PNG is preferable for Classic Shirt work because transparent areas, sharp lines, and exact colors survive export. WebP can be imported for convenience, but the maker always downloads PNG.
Designing torso and sleeve surfaces
A Shirt design must make sense across several connected surfaces. A stripe that leaves the torso front may need to continue on a side panel and align with the back. A sleeve cuff needs consistent placement on the front, back, side, top, and bottom arm faces. Small mismatches can become conspicuous seams on a rotating avatar.
Plan the design before adding decoration. Establish the main fabric color, define collar and sleeve boundaries, then add highlights, shadows, logos, buttons, pockets, or patterns. Check edge pixels on adjacent panels. Mirroring can be useful for symmetrical sleeves, but deliberately asymmetrical artwork should be tested from both sides.
The flat canvas cannot show the final body shape by itself. Use Roblox Studio with a Block Avatar rig to inspect front, back, arms, shoulders, and underside surfaces. Rotate the rig under different lighting. Return to this maker with the flattened PNG, make targeted corrections, and download another exact-size version.
Transparency, clearing, and color choices
Transparent pixels allow the underlying avatar or other applicable appearance elements to remain visible. The clear command removes every pixel, while the eraser removes only the brushed path. A white brush is not equivalent to an eraser: white remains visible, but erased alpha does not.
Choose colors with avatar lighting and compression in mind. Very dark neighboring colors can merge visually, while saturated edge pixels may look brighter under certain environments. Hard-edged pixel art is easiest to control with small brush sizes. If imported art contains soft antialiasing, partially transparent edge pixels may blend differently against different avatar colors.
The color picker uses standard browser color input and applies an opaque color. For translucent artwork, prepare alpha in another editor and import the PNG, then use this maker for placement or opaque corrections. The exported canvas preserves existing alpha information.
What this maker does not do
The tool does not automatically identify torso and arm regions, generate clothing from a prompt, convert layered clothing, create a 3D mesh, upload to Marketplace, or verify intellectual-property rights. Classic Clothing is distinct from modern layered clothing, which involves meshes, cages, rigging, skinning, and additional validation requirements.
A downloaded file is not a guarantee of platform acceptance. Roblox may apply creator eligibility rules, upload fees, moderation, naming requirements, technical validation, and policy changes. Review current official documentation before publishing. Avoid copyrighted characters, logos, or another creator’s artwork unless you have the necessary permission.

Local processing and privacy
Image decoding, fitting, painting, erasing, history, resetting, and PNG encoding happen inside your browser. The maker does not require sign-in, save a cloud project, expose a public gallery, or transmit selected image pixels and filenames to SkinEditor.org. Refreshing or closing the page removes the temporary editing state, so download work you want to keep.
Local processing reduces unnecessary privacy and copyright exposure, but it also means there is no server backup or cross-device synchronization. Save versions with clear filenames when iterating. The downloaded filename identifies it as a 585 × 559 Classic Shirt working image.
Frequently asked questions
What size does the Roblox shirt maker download?
Every download is a 585 × 559 PNG, matching the full canvas dimensions of the current official Classic Shirt template.
Can I upload an existing Shirt template?
Yes. PNG, JPG, and WebP images can be used as a base. An exact-size template remains at native dimensions; other shapes are proportionally fitted and centered.
Does the tool upload my Shirt to Roblox?
No. It only creates a local PNG. You must test and upload through the current official Roblox workflow.
Can I make Roblox Pants with this canvas?
Classic Pants use the same full image dimensions but a different body mapping. Use a dedicated Pants maker and the official Pants template so the intent, guidance, and body panels remain clear.
Why does my design look different on an avatar?
The 2D template wraps around multiple 3D surfaces. Misaligned panel edges, artwork on the wrong face, avatar rig differences, lighting, and transparency can all change the result. Test on a Block Avatar rig before publishing.
