QR codes, passwords, business names, price quotes and more — 12 free tools that run right in your browser, on any device.
Everything is free and works instantly — nothing is uploaded to a server.
Turn any link or text into a QR code and download it as an image — free, instantly.
Tip: test the code with your phone camera before printing it.
A QR code turns a website address, Wi-Fi details or plain text into a square barcode that any smartphone camera can scan. This free QR code generator creates your code directly in your browser — nothing is sent to a server — and lets you download it as a PNG image for menus, flyers, business cards, packaging or posters.
No. These are static QR codes: the link is encoded permanently inside the image, so the code works forever and never redirects through a third-party service.
Create a random, secure password in one click.
Security experts recommend at least 14–16 characters mixing uppercase, lowercase, numbers and symbols. Every extra character multiplies the time needed to crack a password. This generator uses your browser's cryptographic random number generator — passwords are created on your device and never transmitted anywhere.
Never. Use a unique password for every account and store them in a password manager, so one leaked site can't compromise your email or banking.
Enter a keyword that describes your business and get instant name ideas.
The best business names are short, easy to spell, easy to say out loud, and hint at what you do. Before committing, check that the matching .com (or your local domain) is available, search your country's trademark registry, and make sure the social media handles are free.
Yes — the ideas generated here are free to use. Just verify availability with your local business registry before registering.
Build a professional quote and print it or save it as a PDF — free.
| Description | Qty | Unit price |
|---|
A professional quote should show your business details, the client's name, a quote number and date, an itemized list of products or services with quantities and unit prices, any tax, the total, and how long the quote stays valid. Clear quotes get approved faster and protect both sides if there's a dispute later.
A quote is the price you propose before the work; an invoice is the bill you send after. You can reuse this tool for simple invoices by changing the title in the notes.
Count words, characters, sentences and reading time as you type.
Word and character counts matter for essays, blog posts, meta descriptions (about 155 characters), X/Twitter posts (280 characters), and ad copy. Reading time here is estimated at 200 words per minute, the average adult reading speed.
Generate unique username ideas for gaming, social media or any account.
Keep it under 15 characters so it fits on every platform, avoid personal information like your birth year or real full name, and check availability on the platforms you use most before settling on one.
Placeholder text for designs, mockups and layouts.
Lorem ipsum is scrambled Latin used as placeholder text since the 1500s. Designers use it to fill layouts so viewers judge the design instead of reading the words. Generate as many paragraphs as you need and paste them into your mockup.
Pick random numbers for draws, raffles, games and decisions.
This tool uses your browser's built-in cryptographically secure random source, the same quality of randomness used for security keys — perfect for raffles, lottery-style picks, classroom games or deciding who goes first.
Generate matching 5-color palettes for logos, websites and designs. Click any color to copy its code.
Click a color to copy its hex code (e.g. #2456C8).
Each palette starts from a random base hue and adds harmonious variations — a darker shade, a lighter tint, a neighboring accent and a contrasting complementary color. That structure (dominant, support, accent, contrast, background) maps directly onto real design work.
Instant tagline ideas for your brand or product.
Great slogans are short (under 8 words), concrete, and easy to say out loud. Use these ideas as starting points — swap in your brand's real benefit and read the result aloud to test the rhythm.
Generate a ready-to-paste hashtag set for Instagram, TikTok and X.
Current best practice is 3–8 highly relevant hashtags rather than 30 generic ones. Mix one or two broad tags with several niche tags that describe exactly what's in your post — niche tags face less competition and reach more interested viewers.
Find your exact age in years, months and days — plus your next birthday.
The calculator counts complete years first, then complete months, then remaining days, correctly handling leap years and different month lengths — the same method used on official forms.
Generate universally unique identifiers (UUID v4) for development and databases.
A UUID (universally unique identifier) is a 128-bit value like 3f9c1a2e-… used to identify records in databases, files and APIs. Version 4 UUIDs are generated from random data — the chance of two ever colliding is effectively zero.
