About Icon Font Reference
Icon Font Reference is an web utility tool that runs in your browser. Quick reference for popular icon libraries — Material Icons, Font Awesome, Bootstrap Icons, Heroicons, and Lucide. The page you are reading is the same workspace you will use to do the work: pick a file or paste your input, choose the options that matter to you, and the tool produces the result on your device.
Technically, the work is done by standard browser APIs, loaded as part of the page. Inputs are recognised automatically and validated before the engine begins processing. Files up to 0 MB are supported per run; that ceiling keeps browser memory usage stable on a wide range of devices.
Icon Font Reference runs the entire transformation inside your browser. The file is read by JavaScript running in the page, processed in-memory by standard browser APIs, and written back as a download. The browser is the runtime; the page is the interface. You can confirm what the tool does by opening the developer-tools Network tab during a run — the only requests are for the page's own static assets.
Typical users of Icon Font Reference include analysts pulling lightweight reports, marketers running campaigns and site owners auditing pages. The thread connecting all of them is the same: a focused web and productivity utility task that fits cleanly into a browser tab and benefits from a tool with sensible defaults and minimal setup.
Most people land on Icon Font Reference via a search at the moment they actually need the tool. That shapes the design: the page is a single screen with the input on one side, the controls in the middle, and the result on the other, so a first-time visitor can complete the job without reading documentation.
The architecture imposes only the limits the browser itself imposes. The published 0 MB ceiling is conservative; most modern devices comfortably handle inputs up to that size, and the cap exists so the tool degrades gracefully on phones and budget laptops rather than running out of memory.
As a workflow component, Icon Font Reference is the part you reach for when a single, well-defined web and productivity utility step needs to happen. It performs that step and returns a standard file you can carry into the next part of your pipeline.
Icon Font Reference keeps the control set focused. Every option on the page is there because a real workflow needs it, and the defaults aim at the most common case so a first-time user can get the right output without changing any settings.
Icon Font Reference returns the result as a download. If you are running multiple jobs, the output names will not collide as long as the input names differ. You can re-run with different settings as many times as you like; each run produces a fresh file with no caching trickery in between.
Some context on why Icon Font Reference exists in this form: modern File APIs, high-performance JavaScript engines, and well-maintained open-source libraries now make it possible to perform web and productivity utility work entirely in the browser. Icon Font Reference is built on top of that capability, which is why a single page can host the full pipeline.
If you also use a command-line tool for icon font reference, Icon Font Reference is a convenient alternative for the times you are on a different machine or helping someone who is not comfortable in a terminal. The output is a standard file in the format documented above.
If you want to get the most out of Icon Font Reference, three small habits help. Drag-and-drop is faster than the file picker once you get used to it. The keyboard shortcut for downloading the result is whatever your browser uses for "save link as," because the result is a normal download. And if you are working on a sensitive file, processing in an Incognito or Private window is a good extra layer — it leaves no trace in browser history when the tab closes.
Common gotchas worth flagging: the supported formats are listed in the upload area. The 0 MB ceiling is per-file, not per-session; you can run as many separate jobs as you like, but a single oversized input will be rejected on load.
Icon Font Reference is intentionally narrow in scope so the common case is fast and the result is predictable. If you ever need a variation it does not cover, browse the rest of the catalog — there is a good chance an adjacent tool already exists, and switching between tools is just a matter of opening another tab.
How it works
- 1Reach the Icon Font Reference page in your browser to begin.
- 2Add your web utility input by dropping it onto the page or browsing for it.
- 3Pick any non-default settings you need. Most users leave the defaults alone for the first run and only revisit if the result needs tuning.
- 4Click to start the job. The engine (standard browser APIs) processes the input in the page; you can watch the progress indicator until it completes.
- 5Download the result. The file is generated in your browser and saved through your normal download flow.
- 6Repeat the process for additional inputs whenever you need to. The page stays loaded, so subsequent runs are quick.

FAQ
Which library should I use?
Material Icons for Google ecosystem, Font Awesome for variety, Bootstrap Icons for Bootstrap projects, Lucide for modern React.
Icon font vs SVG?
Icon fonts are easier to set up. SVGs offer better accessibility, styling control, and tree-shaking.
Are they free?
All listed libraries have free tiers. Font Awesome Pro and some others offer premium icons.
How do I add icons?
Add the CDN link to your HTML, then use the appropriate class or element syntax shown in the reference.
Can I customize icon colors?
Yes — icon fonts inherit the CSS color property. SVG icons can be styled with fill and stroke.
Private?
Yes — reference is generated locally.
Does Icon Font Reference need an internet connection to run?
Once the page is loaded, Icon Font Reference can complete jobs without an active internet connection — the engine is bundled with the page, so there is no per-job network call. The initial page load does require a connection (to fetch the static assets), but after that you can disconnect entirely and the tool will still work. This is a side-effect of the local-first architecture, not a deliberate "offline mode" feature.
Do I need a specific browser to use Icon Font Reference?
Icon Font Reference works in any modern browser released in the last few years — Chrome, Edge, Firefox, Safari, Brave, Arc and the major Chromium derivatives are all supported. The underlying engine relies on widely-supported web APIs, so there is nothing exotic to install. If you are on a very old browser version and the tool fails to load, updating to the latest release of your preferred browser is the only fix needed.
Can I use Icon Font Reference with formats other than the defaults?
The accepted formats are listed in the upload area on the tool itself. If your input is in a format that is not directly supported, convert it first using one of Favtoo's converter tools — every Favtoo converter outputs a file that is a clean input to the next tool in the chain.
What is the maximum file size for Icon Font Reference?
Inputs are capped at 0 MB per file, which keeps memory usage stable across phones, tablets and older laptops. You can run Icon Font Reference as often as you need; every run produces a full-quality result.
Is Icon Font Reference really free?
Icon Font Reference is free to use. The processing runs in your browser, which keeps the per-user cost low enough that the tool can be offered openly. The download is the same file the engine produced — you can use it for as many runs as you need.
Is there a programmatic version of Icon Font Reference?
Icon Font Reference is a browser-only tool by design and does not expose a hosted API. The reason is the same as the privacy story: there is no Favtoo backend doing the work, so there is no service to call. If you need to script the same transformation, the underlying engine (standard browser APIs) is open-source and can be used directly from your own code.
Are jobs run with Icon Font Reference stored anywhere?
Favtoo keeps no copy of your file because Favtoo never receives your file. Icon Font Reference runs entirely in your browser, the input is held only in your tab's memory, and closing the tab discards it. There is no opt-in cloud history, no "recent jobs" panel synced to an account, and no server-side retention to configure — the architecture simply has nowhere for your file to be stored.
