About BloxShirt
BloxShirt offers free browser editors that help Roblox creators go from artwork to an uploadable classic clothing file, without an account, a subscription or a server upload.
What you can do here
Shirt Maker
Place art on the official 585 × 559 Shirt template and preview it on an R6 or R15 avatar.
Pants Maker
The same editor and template layout for the 585 × 559 Pants file.
T-Shirt Maker
Turn a picture into the 512 × 512 square Roblox shows on the torso front.
Clothing Tester
Drop a shirt or pants PNG, or mix our templates into an outfit, and check it on a 3D avatar before paying Roblox's upload fee.
Thumbnail Maker
Build a 1920 × 1080 game thumbnail or a 512 × 512 icon with a real-size preview.
Why it exists
Roblox charges 80 Robux to upload a piece of classic clothing and does not refund a rejected item. Getting the template size, face layout or transparency wrong is an easy, avoidable way to lose that fee. BloxShirt exists to catch those mistakes for free, before you spend anything — and to give creators a working set of templates and a preview close enough to Roblox's own R6/R15 avatars to be useful.
How your images are handled
HTML canvas and WebGL in your browser
The free editors on this site run entirely in your browser. Uploaded images are drawn to an HTML canvas and the 3D preview runs on WebGL.
Free editor images stay on your device
Images you open in the free editors are never uploaded to a server or stored by us. The free Shirt/Pants makers read selected files through local blob URLs and draw them on canvas; downloads use canvas-generated PNG blobs. Analytics still run on the site, and AI generation uses server processing. Closing the tab clears the free editor image. See the Privacy Policy for the full picture.
Compatibility and maintenance
On October 3, 2026, we checked the Creator Hub classic clothing documentation against our template geometry and check logic: Shirt/Pants face sizes, the size check, transparency coverage and Studio testing instructions. This was a documentation and source review, not a Roblox Studio import test or moderation approval.
This update adds per-face coverage, intentional-transparency notes, manual side-edge inspection and local diagnostic demos. These checks do not certify visual continuity. Current official classic clothing documentation.
AI generator
The AI generator sends your prompt to our configured AI provider to create a complete clothing template. Google sign-in and one-time credit purchases support the AI generator.
Our relationship with Roblox
BloxShirt is an independent, unofficial tool for Roblox creators. It is not affiliated with, endorsed by or sponsored by Roblox Corporation, and does not use Roblox's logo, trademarks or brand fonts. "Roblox" and related marks belong to Roblox Corporation. The templates and previews here are our own work, built from Roblox's public developer documentation, and the final word on whether an item works is always Roblox Studio and the Roblox upload process itself.
