Frequently Asked Questions

Everything you need to know about image resizing

What are the correct Roblox image dimensions in 2026?

Roblox's required image dimensions for 2026: Game Icon — 512×512 px (1:1); Game Thumbnail — 1920×1080 px (16:9); Group Emblem — 420×420 px (1:1); Shirt/Pants Template — 585×559 px; T-Shirt Template — 512×512 px (1:1); Game Pass Icon — 150×150 px (1:1). All formats are pre-set in this tool.

What size is a Roblox game icon?

Roblox game icons must be 512×512 px (1:1 square). The game icon appears in the Roblox search results, game detail pages, and in player libraries. Uploading at exactly 512×512 px ensures the icon renders sharply without being scaled by Roblox. Icons with text or logos should be simple enough to be recognizable at small display sizes.

What are the correct Roblox game thumbnail dimensions?

Roblox game thumbnails must be 1920×1080 px (16:9 ratio). Thumbnails are the main promotional images shown in search results and on the game's detail page. They are the most important visual for attracting players. High-quality, eye-catching thumbnails at the full 1920×1080 resolution significantly improve click-through rates.

What size is a Roblox shirt or pants template?

Roblox shirt and pants templates must be exactly 585×559 px. This is a fixed canvas size that maps onto the Roblox avatar mesh. The template includes specific zones for different body parts (front, back, sleeves). If you resize your clothing design to any other dimensions, it will be distorted or misaligned when applied to the avatar. This preset outputs exactly 585×559 px.

What size is a Roblox T-shirt template?

Roblox T-shirt (graphic tee) templates must be 512×512 px (1:1 square). Unlike shirts and pants which have a complex multi-zone template, T-shirts use a simple square image that is applied to the front of the avatar's torso. This is a simpler format for creators just starting with Roblox clothing design.

What size is a Roblox group emblem?

Roblox group emblems should be 420×420 px (1:1 square). The emblem is the visual identity of your group and appears on the group page, in member lists, and in search results. Keep the design simple and bold enough to be recognizable at small display sizes.

What size is a Roblox game pass icon?

Roblox game pass icons should be 150×150 px (1:1 square). Game pass icons appear in the passes section of a game's detail page. At this small display size, use a clean, simple icon with high contrast so players can quickly identify what the pass contains.

Can I resize multiple Roblox assets at once?

Yes. You can upload up to 12 images at once and resize them all to the same Roblox format in a single step. This is useful for preparing icons for a set of game passes, thumbnails for multiple games, or a clothing catalog.

What file format does Roblox require for image uploads?

Roblox accepts JPG and PNG for most asset types. For clothing templates and any image that requires a transparent background (like decals with transparency), use PNG. For game thumbnails and icons where transparency isn't needed, JPG provides smaller file sizes. Roblox has a maximum file size limit of 20 MB for most uploads — the editor's file size limiter helps you stay within this.

Why was my Roblox image upload rejected?

Roblox image uploads are rejected for three main reasons: wrong dimensions (the image is not the required pixel size), file size too large, or content moderation. For dimension issues, use this tool to resize to the exact required size before uploading. For file size issues, use the editor's file size limiter. Content moderation rejections require changes to the image content itself.

Is it safe to use this tool for unreleased game assets?

Yes. All resizing happens entirely in your browser — your assets are never uploaded to any server. This makes it completely private and safe for unreleased games, upcoming clothing drops, or any creative work you want to keep confidential.

Do I need an account or login?

No. Resize images for Roblox completely free — no account, no login, no watermarks. Just upload and download.
