Free Online Utility Tools – QR Codes, Passwords & Invoices
General-purpose tools for small business owners, freelancers and anyone who needs something done quickly: a QR code for a menu or Wi-Fi network, a strong password, or a professional invoice as a PDF.
Passwords are generated with your browser's cryptographic random number generator and are never transmitted. Invoices and QR codes are built on your device and downloaded directly.
QR Code Generator
Use this QR code generator to turn a link, a note, Wi-Fi login details or a full vCard contact into a scannable code. Pick your own colours and save a PNG up to 2048 pixels or an SVG for print.
Password Generator
This password generator builds random passwords from 4 to 128 characters using the browser's cryptographic random source. Every character type you tick is guaranteed to appear, and look-alikes such as l, 1 and O can be left out.
Invoice Generator
An invoice generator that turns a short form into a tidy A4 PDF with your logo, line items, discount and tax. It supports 25 currencies and suggests the next invoice number from details it remembers.
Signature Maker
Create an e-signature by drawing with a finger or mouse, typing your name in a handwriting style, or uploading a photo or scan of one signed on paper. The result is trimmed and saved as a transparent PNG ready for documents.
QR Code Scanner
Read any QR code from your camera, an uploaded photo or a pasted screenshot with this QR code scanner. It recognises Wi-Fi networks, contact cards and links, and flags suspicious addresses before you open them.
Barcode Generator
Make Code 128, EAN-13, UPC-A, Code 39, ITF-14 and other barcodes with a live preview as you type. Check digits are calculated automatically, and each code downloads as a high-resolution PNG or scalable SVG.
Password Strength Checker
Test how strong a password really is with a checker that spots common words, keyboard runs, dates and leetspeak. It gives a score from 0 to 4 plus crack-time estimates for online and offline attacks.
Random Number Generator
Draw random numbers from any range, including negatives and decimals, with an option for unique results only. A built-in list picker also chooses winners from names, teams or prizes in the order they are drawn.
Coin Flip
Toss a virtual coin for heads or tails, or flip up to ten coins at once for group decisions. A running tally shows percentages for each side along with your current and longest streak.
Dice Roller
Roll up to ten dice at a time, from a classic d6 to a d20 or d100, and see every face plus the total. Add a plus or minus modifier for tabletop games and review the last 20 rolls.
Online Stopwatch
Time anything to the hundredth of a second with an online stopwatch that records unlimited laps. Fastest and slowest laps are highlighted, and the time keeps going when you switch tabs or reload the page.
Countdown Timer
Set a countdown timer for anything from one second to nearly 100 hours, or start a preset such as 5 or 30 minutes in one tap. An alarm sounds at zero and the tab title flashes when time is up.
Pomodoro Timer
Work in focused blocks with a Pomodoro timer that runs 25-minute sessions separated by short and long breaks. Session lengths are editable, and a task label reminds you what each focus round is for.
Online Notepad
Jot down ideas in an online notepad that autosaves every change and keeps several named notes side by side. Open or download .txt files, search inside a note and print just the text when needed.
Resume Builder
Build an ATS-friendly resume by filling in a form and choosing a Classic, Modern or Compact template. The live preview matches the final PDF page by page, on A4 or US Letter paper.
