Help & FAQ - Randomizer Tools

General FAQ

What is Randomizer Tools?

Randomizer Tools is a collection of privacy-focused randomization utilities that work entirely in your browser. We provide tools for generating passwords, random numbers, creating teams, making decisions, generating color palettes, and more—all without collecting your data.

Do I need to create an account?

No! All our tools work immediately without any registration or account creation. This is part of our privacy-first approach—we can't collect what we don't have.

Are these tools really free?

Yes, all our randomization tools are completely free to use. We may display advertisements to support the site, but there are no subscription fees, limits, or hidden costs.

Can I use these tools on my phone or tablet?

Absolutely! Our tools are built with responsive design and work great on desktops, tablets, and smartphones. All functionality is preserved across devices.

Can I use these tools offline?

Once loaded, most basic functionality will work offline since processing happens in your browser. However, you'll need an internet connection to initially load the tools and for some features like downloading files.

Tool-Specific Guides

Password Generator

How to Use:

Adjust the password length using the slider (4-128 characters)
Select how many passwords you want to generate
Choose character types: uppercase, lowercase, numbers, symbols
Optionally exclude ambiguous or similar characters
Click "Generate Passwords" to create secure passwords
Click the copy button next to any password to copy it

Best Practices:

Use at least 12 characters for good security
Include multiple character types for stronger passwords
Generate unique passwords for each account
Store passwords in a secure password manager

Common Questions:

Q: How secure are the generated passwords?

A: We use cryptographically secure random number generation (Web Crypto API) to ensure unpredictable, high-entropy passwords suitable for security applications.

Q: What does "exclude ambiguous characters" mean?

A: This removes characters that can look similar in certain fonts, like 0 (zero) and O (letter O), or l (lowercase L) and I (uppercase i). This helps prevent typos when entering passwords.

Team Generator

How to Use:

Enter participant names, one per line, in the text area
Choose number of teams or use "Auto" for balanced sizing
If using auto, set preferred team size
Select team naming scheme (numbers, letters, colors, animals)
Click "Generate Teams" to create balanced teams
Use "Shuffle Again" to reorganize with same settings

Applications:

Sports teams and recreational activities
Group projects in education or workplace
Party games and icebreaker activities
Workshop breakout groups
Online gaming team formation

Q: How does the auto-balancing work?

A: The tool distributes participants as evenly as possible. If the total doesn't divide perfectly, some teams will have one extra member to ensure everyone is included.

Color Palette Generator

How to Use:

Choose number of colors (3-8)
Select palette type (monochromatic, complementary, etc.)
Optionally set a base color
Click "Generate Palette" to create harmonious colors
Copy individual colors or export the entire palette
Save favorite palettes for future use

Palette Types Explained:

Monochromatic: Different shades/tints of the same color
Analogous: Colors next to each other on the color wheel
Complementary: Colors opposite each other on the wheel
Triadic: Three evenly spaced colors on the wheel
Pastel: Soft, light colors with low saturation
Vibrant: Bright, high-saturation colors

Q: What export formats are available?

A: You can export palettes as CSS variables, JSON arrays, or plain text lists. The CSS format is particularly useful for web development projects.

Date Generator

How to Use:

Set start and end dates for your desired range
Choose how many random dates to generate
Select your preferred date format
Use quick presets for common ranges (this year, last decade, etc.)
Optionally exclude weekends or holidays
Include random times if needed
Click "Generate Dates" to create random dates

Common Use Cases:

Test data for software applications
Random sampling for research studies
Event planning and scheduling exercises
Creative writing and storytelling
Database seeding for development

Other Tools Quick Guide

Random Number Generator

Troubleshooting

The tools aren't working or loading properly

Try these solutions:

Refresh the page or clear your browser cache
Make sure JavaScript is enabled in your browser
Try using a different browser or update your current one
Disable browser extensions temporarily to check for conflicts
Check if you have a stable internet connection

Copy to clipboard isn't working

Clipboard issues can be caused by:

Browser security settings blocking clipboard access
Using HTTP instead of HTTPS (modern browsers require secure connections)
Browser extensions interfering with clipboard functionality
Manually select and copy the text as an alternative

Downloads aren't working

Download problems might be due to:

Browser popup blocker preventing the download
Browser security settings blocking file downloads
Insufficient storage space on your device
Try right-clicking the download button and selecting "Save Link As"

The interface looks broken or scrambled

Display issues might be resolved by:

Clearing your browser cache and cookies
Disabling browser zoom or setting it to 100%
Trying a different browser to see if it's browser-specific
Checking if your browser supports modern CSS features

Tools are running slowly

Performance can be improved by:

Closing other browser tabs and applications
Generating smaller batches (e.g., 10 passwords instead of 100)
Using a more powerful device for complex operations
Ensuring your browser is up to date

Privacy & Security

How do you protect my privacy?

Our privacy protection works through technical design:

Client-side processing: All tools run in your browser, not on our servers
No data transmission: Your inputs and results never leave your device
No accounts: We can't collect personal data we never ask for
Minimal cookies: Only for basic functionality like theme preferences

How secure are the generated passwords?

Our password generation uses industry-standard security:

Web Crypto API: Browser's built-in cryptographically secure random generator
High entropy: Passwords are truly unpredictable
No patterns: Each character is independently random
No storage: Passwords aren't saved anywhere

What about the randomness quality of other tools?

All our tools use the same secure random number generation:

Team assignments are cryptographically shuffled
Number generation uses secure random within specified ranges
Color generation uses secure random for hue/saturation/lightness
Date selection uses secure random within date ranges

Can I trust this site with sensitive data?

Yes, but with understanding of what "sensitive" means:

Good for: Generating passwords, creating test data, team assignments
Consider carefully for: High-stakes cryptographic applications
Remember: We process locally, but your browser and device security matters too
Best practice: Use generated passwords in secure password managers

Do you use any tracking or analytics?

We use minimal analytics for site improvement:

Google Analytics: Anonymous usage statistics (which tools are popular, general geographic data)
No personal data: We don't track what you generate or input into tools
No cross-site tracking: We don't follow you around the internet
Ad cookies: If ads are present, they may use cookies for personalization
