Free Online Utility Tools

Free online utility tools cover the miscellaneous tasks that don't fit neatly into a single professional category but come up constantly in everyday workflows. This collection spans design, retail, job seeking, and general productivity.

For developers and designers, the CSS Gradient Generator and CSS Box Shadow Generator provide visual editors that output production-ready CSS code. The Color Palette Generator creates harmonious colour schemes using complementary, analogous, and triadic algorithms — with the ability to lock colours and regenerate the rest.

The QR Code Generator and Barcode Generator handle print and digital distribution needs: create custom QR codes for URLs, contact cards, and WiFi credentials, or generate CODE128, EAN-13, UPC, and CODE39 barcodes for product labelling. The QR Code Scanner decodes QR codes from uploaded images or a live camera feed.

For everyday calculations, the Age Calculator delivers exact age in years, months, and days with a next-birthday countdown. The Unit Converter handles length, weight, temperature, volume, area, speed, time, and digital storage across metric, imperial, and US customary systems. The Random Number Generator uses the Web Crypto API for cryptographically secure values in any range.

A set of focused calculators covers the numbers people look up most: the Percentage Calculator works out increases, decreases, and "X is what percent of Y" in one place, the Loan EMI Calculator breaks a loan into monthly instalments with total interest, and the BMI Calculator reports body mass index against the standard categories. The Stopwatch & Timer adds precise timing with lap splits and a countdown alarm for workouts, cooking, and focus sessions.

Six more cover dates, money and measurements. The Date Difference Calculator counts the exact span between two dates in real calendar months rather than dividing by thirty, and the Time Zone Converter compares cities side by side with daylight saving applied for the date you pick. The Compound Interest Calculator projects savings growth month by month with contributions, splitting what you put in from what the interest added. The Aspect Ratio Calculator scales dimensions without distortion in either direction, while the Roman Numeral Converter and Number to Words handle the two notations people still have to write by hand — the latter with proper currency wording for cheques.

Eight more cover everyday needs that are too small for an app. The Online Notepad autosaves as you type with no account, the Random Picker Wheel draws names with cryptographic fairness rather than reading off wherever an animation stops, and the Invoice Generator produces a clean PDF invoice with no watermark or monthly cap. The Colour Contrast Checker tests text against WCAG AA and AAA and suggests the closest passing colour when a pair fails, while the Pomodoro Timer keeps accurate time even in a background tab. Rounding out the set, the Tip, Discount and Tax Calculator handles all three including extracting tax from an inclusive price, the GPA Calculator weights by credit hours properly, and the Dice Roller and Coin Flip uses rejection sampling so every face is genuinely equally likely.

The Reading Time Calculator estimates how long any piece of content takes to read or speak — invaluable for content planners and presenters. The ATS CV Template Generator rounds out the collection, producing clean, recruiter-friendly PDF resumes formatted to pass Applicant Tracking System screening.
