# aiRoblox | Icons and thumbnails for Roblox + Robux calculator > Create your Roblox experience icon and thumbnails with AI and truly crisp text, and calculate your Robux: DevEx, Marketplace fee, and team revenue sharing. - **Source (source):** https://aitoolsforapps.com/airoblox-icons-thumbnails-and-robux-calculator-213 - **Platform (platform):** AiToolsForApps - **Language (language):** en - **Updated (updated):** 2026-10-27 ## In summary - Icons, thumbnails and Robux for Roblox creators - For the creator who publishes experiences and sells on the Marketplace: generate the 512×512 icon and the 1920×1080 thumbnails with crisp text —because the AI doesn't write the text, it's composited afterwards—, check how your icon will look at 64 pixels in the mobile feed and calculate what you'll actually take home with the current DevEx rates and commissions. - Icons, thumbnails and badges with text you can actually read: 512×512 icon, 1920×1080 thumbnails and 512×512 badge and game pass icons. Choose from 7 genres, 5 palettes and 5 type styles, and you can upload up to 2 screenshots of your game as style reference. The AI only paints the background: your title is composited afterwards as a vector on a gradient plate, so it never comes out with warped letters or spelling mistakes. On badges and passes, what matters stays inside the safe circle and you see it already masked before downloading the square Roblox asks for. - The 64-pixel test and 5 hooks for A/B testing: Roblox lets you A/B test thumbnails, but not the game icon: here you see yours genuinely shrunk to 64 pixels, dropped into a discovery grid next to other cards, plus a verdict with four measured metrics —overall contrast, figure against background, detail density and actual text height—, not an opaque AI score. For thumbnails you request 1, 3 or 5 variants and each one pushes a different hook: epic action, mystery, reward, hero or novelty, labelled with its hypothesis so you know what you're testing when you look at the results. - DevEx, commissions and splits with verified rates: Two-way converter —from Robux to your currency and from your currency to Robux— with the three current DevEx rates, the 30,000 Robux minimum and real European Central Bank exchange rates across 30 currencies. The commission isn't 30% for everything: the calculator asks what you're selling (Game Pass, Avatar Marketplace item, in-experience item or limited resale) and it also works in reverse, telling you what price to publish at to receive an exact net amount. And the simulator splits revenue among your team with 100% adjustment and without losing a single Robux along the way. ## Your experience isn't getting clicks and you don't know how many Robux you actually have left after commissions? On the Roblox front page, the click is decided by the icon, and on mobile —where most of the traffic comes from— it renders at around 64 pixels: what looks spectacular on desktop is a blur there. aiRoblox generates the art with AI, overlays the text afterwards programmatically so it comes out crisp and typo-free, and shows you your icon genuinely shrunk to 64 pixels next to other cards, with a legibility verdict measured pixel by pixel. And on the money side: the three DevEx rates, the four sale types with their real commission —a Game Pass leaves you 70%, an Avatar Marketplace item 30%— and the split among your team, with the date each figure was verified in plain sight. ## What comes out of here gets uploaded to Roblox as-is Three things that don't usually go together: AI-generated art, typography that doesn't break and numbers that add up with today's rates. ### Icons, thumbnails and badges with text you can actually read 512×512 icon, 1920×1080 thumbnails and 512×512 badge and game pass icons.

The commission isn't 30% for everything: the calculator asks what you're selling (Game Pass, Avatar Marketplace item, in-experience item or limited resale) and it also works in reverse, telling you what price to publish at to receive an exact net amount.

No need to write prompts: the server does that for you. 2. **Pick a format and generate** — Icon, thumbnails or badge, with your headline text and the type style you prefer. Each format is generated at its native size; a square is never stretched to 16:9. 3. **Check, download and do the math** — Look at the legibility verdict and the mobile feed test, download piece by piece or the ZIP pack with a README that says where each file goes, and hop over to the calculator to see what you'll earn. ## Frequently Asked Questions ### Do I need to sign up to use it? Not to try it or to download: you can generate your pieces and download them without creating an account. Signing up means your project won't be lost when you close the browser and you can come back to it from another device; when you do, the work you already had stays with you. The app also warns you if your browser won't be able to save anything. ### Does the AI write the text on the icon? No, and that's on purpose. Image generators write badly: letters come out warped and words invented, and it's the flaw you notice most in AI-made thumbnails. Here the AI paints only the background, with an explicit instruction not to include text, letters or logos, and your title is composited afterwards as a vector on a gradient plate that covers any residual scribble. The result reads exactly as you wrote it, accents included, and it's crisp at any size. ### Where do the DevEx rates and commissions come from? From Roblox's official documentation, and the app shows on screen the date they were verified. The rates aren't hardcoded: they live in configuration, so when Roblox changes one it's updated without touching the app. If a figure is missing, the calculator says it's unavailable instead of making up a number: with real money, better not to calculate than to calculate wrong. Currency conversion uses European Central Bank exchange rates and, if the source doesn't respond, the last known value is shown labelled with its date. ### Are you affiliated with Roblox? And can I ask for cheat scripts or free Robux? No and no. aiRoblox is not affiliated with, sponsored by or endorsed by Roblox Corporation; "Roblox" and "Robux" are trademarks of their owner and are used here only to describe what the tool is for. And there's a server-side filter that denies exploits, cheat scripts, auto-farm, Robux generators and third-party brands or characters: those are things that can cost you your account, and when the filter denies a request no generation is consumed. This is a tool for people who create and sell on Roblox. - [Blog](https://aitoolsforapps.com/airoblox-icons-thumbnails-and-robux-calculator-213/blog) ## About the platform **aiRoblox — Icons, thumbnails, and Roblox economy with AI** — an app by AiToolsForApps.
