What is Steam Tools Hub?
Steam Tools Hub at Steam Tools Hub is a collection of small browser-based utilities for Steam's community items — trading cards, emoticons and backgrounds — plus a few tools that work with your own Steam library and inventory. Each tool is a separate web app, so you open only the one you need rather than working inside a single dashboard.
What the tools do
- Trading Cards: Statistics on Steam trading card sets, kept up to date.
- Emoticons: Browse, filter and sort a current list of Steam emoticons on one page.
- Backgrounds: The same browse, filter and sort approach for Steam profile backgrounds.
- Mosaticon: Builds a mosaic of an image you choose using Steam emoticons you own.
- Games Filter: Shows the overlap between users' Steam game libraries and filters that shared set by category.
- Item Value Sorter: Loads your Steam Community items and sorts them by market value or filters them by type.
Who it suits
The catalog-style tools (cards, emoticons, backgrounds) are most useful if you collect or trade these items and want to search and compare them in a faster, more filterable view than Steam's own pages. The Games Filter is aimed at groups — for example, a friend group deciding what to play together by narrowing down titles everyone owns. Mosaticon is a creative extra for people who already have a stock of emoticons and want to turn them into an image.
Trade-offs to keep in mind
These are lightweight, focused web apps rather than a managed service, and the site's own footer dates it to 2013–2019, so some tools may lag behind Steam's current item catalog or interface changes. The inventory-based tools also depend on loading your Steam Community items, which is worth checking works before you rely on it.
A practical next step: if you mainly want to browse collectibles, start with the emoticons or backgrounds tool; if you want to act on your own inventory, try the Item Value Sorter first and confirm it loads your items correctly.
How can I use Steam Tools Hub to find the market value of my Steam inventory items?
Use the Item Value Sorter on Steam Tools Hub: load your Steam Community items into it, then sort them by market value or filter them by item type. That gives you a ranked view of what your inventory is worth rather than a single headline total.
A practical workflow
- Start with the Item Value Sorter. It is the tool built specifically for this job—loading your community items and ordering them by value. Filtering by type lets you look at cards separately from emoticons and backgrounds.
- Cross-check the Trading Cards tool if cards are your main interest. It presents up-to-date stats on card sets, which helps when you want to understand set-level value rather than one item at a time.
- Use Emoticons and Backgrounds for browsing and filtering those categories when you want to identify which of your duplicates are worth listing.
- Try Mosaticon only if you're deciding what to keep. It builds a mosaic from your chosen image using emoticons you own—useful for seeing which emoticons you'd actually use, so you can sell the rest.
What to keep in mind
Market value is not the same as money in hand. Steam Community items sell on the Steam Community Market, where buyers set prices and Valve takes a cut, so the amount you receive is lower than the listed value. Prices also move, especially around sales and new card set releases, so a snapshot from today can look different next week. Treat the sorter as a prioritisation tool—it tells you which items deserve a listing—and confirm the current price on the market before you sell.
If you mainly want to track your collection over time rather than sell, the browsing tools for cards, emoticons and backgrounds are the more comfortable place to start; the value sorter is for the moment you decide to cash out duplicates.
How does the Mosaticon tool on Steam Tools Hub turn my image into a Steam emoticon mosaic?
Mosaticon builds a mosaic of an image you choose from Steam emoticons you already own, so the output is limited to your own inventory rather than the full emoticon catalog.
How the tool works
The process follows the logic of any inventory-based mosaic generator:
- You supply the image. This is the picture you want reproduced as a mosaic.
- The tool reads your owned emoticons. Mosaticon uses "the Steam emoticons you own," per the site, so your available tile set comes from your inventory.
- It maps image regions to emoticons. Each small area of the image is matched to an owned emoticon whose average color best fits that region.
- It assembles the mosaic. The result is a grid of emoticon tiles that, viewed at a distance, resembles your original image.
The site describes Mosaticon only as generating "a mosaic of your chosen image using the Steam emoticons you own." It does not publish details on grid size, color-matching method or export format, so treat those as unknowns rather than features.
What this means in practice
Because the tile set is your inventory, results depend heavily on what you own:
- A large, varied inventory (many emoticons across color ranges) produces a recognizable, detailed mosaic.
- A small or samey inventory (mostly one color family) yields a coarse or tinted result, since the tool has fewer colors to work with.
- Rare emoticons may be used as tiles in the output; the mosaic is a rendering, not a trade, but it is worth knowing your collection is the palette.
A concrete scenario: if you want a recognizable portrait mosaic, check whether your inventory includes emoticons spanning skin tones, shadows and background colors before starting. If not, the practical next step is to broaden your emoticon collection first—or accept a stylized, low-fidelity result.
Decision criterion
Use Mosaticon when you want a personal, inventory-driven mosaic and are comfortable with the constraints of your own collection. If you need precise color fidelity or a guaranteed tile set, an inventory-based approach will not deliver that.
How can I filter and sort Steam trading cards, emoticons, and backgrounds by game or type on Steam Tools Hub?
On Steam Tools Hub, filtering and sorting are split across three separate tools rather than one combined inventory view: Trading Cards gives you statistics on card sets, while Emoticons and Backgrounds each present an up-to-date list you can browse, filter and sort on a single page. So the practical route is to pick the tool that matches the item type, then narrow the list by game and sort it, rather than expecting one screen to cover all three at once.
The Item Value Sorter is the closest thing to a combined view: it loads your Steam Community items and lets you sort them by market value or filter them by type. If your goal is "what in my inventory is worth the most," that is the tool to start with; if your goal is "what exists for this game," the per-type lists are the better fit.
Choosing the right tool
| What you want to do | Tool to use |
|---|---|
| See card-set stats for a game | Trading Cards |
| Browse and filter all emoticons | Emoticons |
| Browse and filter all backgrounds | Backgrounds |
| Sort your own items by value or type | Item Value Sorter |
| Find games you and a friend share | Games Filter |
A concrete example: if you are deciding which badge to craft next, open Trading Cards to check the set, then use the Item Value Sorter to see whether the individual cards you already hold are worth more sold than consumed. For profile decoration, the Emoticons and Backgrounds lists are where you filter down to the game whose art you want.
One limitation worth knowing: the site's own footer dates the project to 2013–2019, so treat any list as current only insofar as the underlying data is refreshed. For anything price-sensitive, cross-check against Steam Community Market before trading.
How can I compare my Steam game library with another user's to find shared games using the Games Filter tool?
Open the Games Filter tool on Steam Tools Hub, enter both Steam profiles (yours and the other user's), and it shows the intersection of your libraries—the games you both own—which you can then narrow by category. The tool's own description frames it exactly that way: it displays the intersection of users' Steam games and lets you filter them by various categories.
Practical steps
- Make sure both libraries are visible. If either profile is set to private, the comparison will come back empty or incomplete; ask the other person to set "Game details" to public, at least temporarily.
- Enter both profiles in the tool and load the comparison.
- Use the category filters to cut the shared list down to what matters—for example, multiplayer or co-op titles if you're picking something to play together, or a genre if you're choosing a gift.
- Cross-check the result against the other person's playtime or recent activity on Steam itself, since ownership doesn't tell you what they actually play.
When this fits
The intersection view is most useful for concrete decisions: finding a co-op game you both already own, planning a session without buying anything new, or spotting overlap before recommending a purchase. For a broader picture of one person's library, a general Steam library viewer is a better fit; for tracking what you've played, Steam's own library is simpler.
One trade-off to keep in mind: the tool reflects ownership, not installed status or playtime, so a shared game may still need downloading on one side before you can play.
Is Steam Tools Hub free to use, and does it require me to log in with my Steam account?
Steam Tools Hub is presented as a set of free browser-based tools; the site lists no pricing, subscriptions or payment options. Whether you need to log in depends on which tool you use.
Tools that work without a Steam login
The browsing tools are reference pages: trading card set stats, an emoticon browser, and a background browser. All three are described as up-to-date lists you can view, sort and filter in one page. For these, you only need to open the page — there is nothing in the description that ties them to your account. A typical use is checking which emoticons exist before deciding what to trade for, or scanning background lists for something you want.
Tools that need your Steam account
Two tools are built around your own library or inventory:
- Item Value Sorter loads your Steam Community items and sorts them by market value or filters them by type. This only makes sense if the tool can see your inventory, so expect to connect your Steam account.
- Games Filter looks at the overlap between users' Steam game libraries and filters by category — again, account-based data.
The Mosaticon tool generates a mosaic from an image using Steam emoticons you own, which also implies access to your account or inventory.
How to decide
If you only want to look up items, use the card, emoticon and background browsers and skip logging in entirely. If you want to value or tidy up your own inventory, log in through Steam's own sign-in page and check what the tool asks for before approving. Steam's login flow lets you review the permissions requested, so read that screen rather than clicking through — and if you're only curious about prices, the public item lists plus the Steam Community Market at Steam Community will often answer the question without connecting anything.
