Free Online Utilities for Everyday Tech Tasks
This is Tooldit's collection of free online utilities — the small, single-purpose tools you reach for when you need a quick answer about your connection, your keyboard, your screen, or the clock. Instead of installing a separate app for each one, you get an internet speed test, a typing speed test, a stopwatch and countdown timer, a random number generator, an IP address lookup, and a screen resolution checker, all in one place and all open in a single tab. Each tool does one thing well and loads instantly.
These are the kinds of checks that come up all the time but rarely warrant downloading software: confirming your Wi-Fi is actually slow before you call your provider, settling a fair draw with a random pick, or grabbing your exact viewport size while building a responsive layout.
What Each Utility Does
Every tool in this category is purpose-built. Here is how to tell them apart and pick the right one:
- Internet Speed Test — measures your real download, upload, and ping by exchanging sample data with a test server, so you can see how fast your connection actually performs right now.
- Typing Speed Test — has you type a passage and reports your words-per-minute and accuracy with live error highlighting as you go.
- Stopwatch & Timer — a stopwatch that records laps plus a countdown timer with a sound alert, for timing anything from workouts to cooking.
- Random Number Generator — picks one or many fair numbers within a range you set, for giveaways, games, sampling, or any decision that should be impartial.
- IP Address Lookup — shows your public IP along with location, ISP, and ASN details for both IPv4 and IPv6, by querying a public IP-information service.
- Screen Resolution Checker — reports your display size, browser viewport, pixel density, and color depth, which is invaluable when designing or debugging layouts.
Why Use Tooldit's Utilities
- Mostly in-browser — the timer, typing test, random number generator, and screen checker run on your device with no data sent anywhere; only the speed test and IP lookup need the network to do their job.
- Free with no limits — no per-day caps, no "upgrade to continue" prompts, and no metered usage.
- No sign-up — none of these tools ask for an account, an email, or a card.
- Nothing to install — each utility is just a web page, so it works the same on Windows, Mac, Chromebook, and phones.
- No clutter — clean results with no watermarks, no bundled extensions, and no upsells.
Real-World Ways People Use These Tools
- Remote workers run the Internet Speed Test before an important video call to confirm their upload speed can handle the meeting.
- Teachers and event hosts use the Random Number Generator to pick a raffle winner or call on a student fairly, with no hidden bias.
- Web designers check the Screen Resolution Checker on each device to confirm a layout renders correctly across breakpoints.
- Students and writers practice the typing test to push their words-per-minute up, and use the countdown timer for focused study or exam-style writing sprints.
Frequently Asked Questions
+Are these online utilities really free to use?
Yes. Every utility on this page is completely free — no trial, no paywall, no daily cap, and no account. There is nothing to install and no card to enter. You open the page, run the tool, and you are done.
+Do any of these tools upload my data to a server?
Most run entirely in your browser and never send your input anywhere — the stopwatch, timer, typing test, random number generator, and screen resolution checker all work offline once the page loads. The speed test exchanges sample data with a test endpoint to measure throughput, and the IP lookup queries a public IP-information service, since both need a network round-trip to do their job.
+How do I choose the right utility for my task?
Match the tool to the question you are asking. Want to know if your connection is slow? Use the Internet Speed Test. Need to time something or count down? Use the Stopwatch & Timer. Practicing keyboard speed? Use the Typing Speed Test. Need a fair pick for a draw? Use the Random Number Generator. Troubleshooting your network or checking your public address? Use the IP Address Lookup. Designing for a screen? Use the Screen Resolution Checker.
+Do these utilities work on a phone or tablet?
Yes. The utilities are built to work in any modern mobile browser, including iOS Safari and Android Chrome. The speed test, IP lookup, and screen resolution checker are especially handy on mobile because phone network and display details are otherwise hard to find.
+Why is the speed test result different from my plan's advertised speed?
Advertised speeds are a best-case ceiling measured to the provider's network. A browser speed test measures the real path between your device and a test server, so Wi-Fi signal, other devices on your network, the test server's distance, and time of day all affect the number. Run it a few times wired and wireless to get a clearer picture.
