Every tool you need,
completely free
Calculators, PDF editors, business tools, converters, and security tools — all in one place. No account, no limits, free forever.
Every tool on Toolriz runs directly in your browser using JavaScript, so your files and data are processed on your own device and never uploaded to a server.
Toolriz is a free online tools platform built for anyone who needs a quick, reliable answer without downloading software or creating an account. Whether you're calculating your exact age in years, months, and days, checking your BMI before a doctor's visit, generating a client invoice, building a QR code for a flyer, or editing a PDF before it goes out the door, every tool here is designed to do one job well and get out of your way.
Most of the calculators and converters on this site run entirely in JavaScript inside your own browser tab. That means when you type your birth date into the age calculator or drop a file into the PDF editor, that data is processed locally on your device — it is not transmitted to, or stored on, a Toolriz server. We built it this way deliberately, because the tools people use most (financial calculators, password generators, document editors) are exactly the tools where privacy matters most.
This page lists the most-used tools on the site. The full catalog, organized by category, is available from the all tools directory.
Pick a tool, get to work
These six tools account for the majority of daily traffic on Toolriz. Each one opens directly to a working form — there's no landing page to click through and no setup screen. Type your input, get your answer.
Age Calculator
Enter a birth date and get your exact age in years, months, days, and total hours — useful for forms, eligibility checks, or just curiosity.
Password Generator
Create a strong, random password with adjustable length and character sets — uppercase, lowercase, numbers, and symbols — generated locally in your browser.
Invoice Generator
Add your business details, line items, and tax rate to build a clean, professional invoice — then download it as a ready-to-send PDF.
BMI Calculator
Enter your height and weight (metric or imperial) to calculate your Body Mass Index and see which standard WHO category it falls into.
QR Code Generator
Paste a URL, Wi-Fi password, or block of text and get a scannable QR code instantly — download it as a PNG for print or digital use.
Advanced PDF Studio
Add text, images, signatures, and annotations to any PDF directly in your browser, then export the edited file without watermarks.
What kind of tool are you looking for?
Toolriz organizes its 100+ tools into a handful of categories. Here's what's inside each one, and when you'd actually reach for it.
Calculators
The calculator category covers everyday math you'd otherwise reach for a spreadsheet to solve: age calculator, BMI calculator, percentage calculator, loan and EMI calculators, GPA calculator, and date-difference tools. Each one is built around a single question — "how old am I exactly," "what's my monthly payment," "what's my body mass index" — and answers it with one form and one result, with no extra steps.
PDF tools
The PDF toolkit handles the document tasks people run into most often: merging multiple PDFs into one file, splitting a single PDF into separate pages, compressing a file that's too large to email, converting PDFs to and from Word or images, and editing existing PDFs with the Advanced PDF Studio. Files are processed in your browser tab, so a contract or ID document never has to leave your device to get resized or merged.
Business & finance tools
This group is built for freelancers and small businesses: the invoice generator creates client-ready PDF invoices with your logo and tax details, alongside a quotation generator, a profit margin calculator, and currency converters using live exchange rates. None of these require setting up a "company account" — you fill the form, you get the document.
Security & privacy tools
The security category includes the password generator, a password strength checker, a text/file hash generator (MD5, SHA-256), and a basic encryption/decryption tool. Every one of these runs client-side by design — a password generated here is created in your browser's own random number function and is never sent anywhere to be logged.
Converters & generators
The catch-all category for everything that turns one format into another: the QR code generator, unit converters (length, weight, temperature), image format converters (JPG to PNG, HEIC to JPG), word and character counters, and a Lorem Ipsum generator for designers and developers who need quick placeholder content.
How does it work?
No account, no install, no waiting. Here's exactly what happens from the moment you land on a tool page to the moment you have your result.
Pick a tool
Search by name or browse the category list above. Every tool opens to its working form immediately — there's no demo screen or "get started" wall in between.
Enter your data
Type into the form or drag a file in, depending on the tool. Calculators validate your input as you type, so you'll see right away if something's missing.
Get your result
Most tools calculate instantly in your browser the moment your input is valid. Copy the result, download the file, or share the link — your session isn't saved anywhere on our end.
Why Toolriz?
Free — forever
There's no premium tier hiding behind a paywall. Every tool — including the PDF editor and invoice generator, which other sites often lock behind a subscription — is fully free, with no usage caps or watermarks on your downloads.
No account needed
Open any tool and start using it immediately. We don't ask for an email address, a password, or a "free trial" sign-up — because the tool itself is the entire product.
Private by design
Most calculations and file edits happen client-side, in JavaScript, inside your browser tab. Your birth date, your file contents, your generated password — none of it is logged or stored on a Toolriz server.
Instant results
Because most tools don't round-trip to a server, results appear the moment you finish typing or uploading. There's no spinner waiting on a backend queue.
Works on any device
Every tool is built with responsive layouts that adapt to phone, tablet, and desktop screens, so you can generate an invoice from your phone between meetings just as easily as from a laptop.
100+ tools, one place
From a tax calculator to a PDF editor to a QR code generator, the tools you'd otherwise collect across five different bookmarked sites live here under one roof, with a consistent layout you only have to learn once.
Built and maintained by a small team of developers
Toolriz is built and maintained by a small team of web developers who use these exact tools in their own freelance and small-business work — which is why the invoice generator outputs a real, usable PDF and the PDF editor doesn't drop a watermark on your file.
Each calculator is checked against known reference formulas (for example, the BMI calculator uses the standard WHO weight-for-height formula, and the age calculator accounts for leap years) before it's published, and tools are updated when users report an edge case that produces a wrong result.
- Formulas are documented. Each calculator page explains the formula or standard it's based on, not just the result.
- Tools are tested against edge cases. Leap years, negative numbers, empty fields, and unusual file formats are part of our test process.
- No ad-driven dark patterns. We don't disguise ads as download buttons or bury the actual tool below filler content.
- Feedback changes the product. Reported bugs and incorrect results are the main driver of updates across the catalog.
