If you are planning to automate web browsers, test websites, or work with browser-based tools, learning how to download ChromeDriver is very important. ChromeDriver is a small but essential tool that allows automation software to control the Google Chrome browser.
Many beginners face problems because they download the wrong version or do not understand how ChromeDriver works. This guide explains everything in simple words, step by step, without using any code, so anyone can understand it easily.
What Is ChromeDriver?
ChromeDriver is a tool that helps software communicate with the Google Chrome browser. It acts as a bridge between automation tools and Chrome.
In simple terms:
- Automation tools give instructions
- ChromeDriver passes those instructions to Chrome
- Chrome performs actions like opening pages, clicking buttons, or filling forms
Without ChromeDriver, Chrome cannot be controlled automatically.
Why Do You Need to Download ChromeDriver?
You need ChromeDriver if you want to:
- Test websites automatically
- Reduce manual testing work
- Automate repetitive browser tasks
- Improve testing accuracy
- Save time and money
Real-Life Example (Dollar Calculation)
Suppose a tester spends 2 hours daily testing a website manually.
- Hourly cost: $25
- Daily cost: 2 × $25 = $50
- Monthly cost (22 working days):
$50 × 22 = $1,100
After automation using ChromeDriver:
- Daily testing time reduces to 30 minutes
- New daily cost: 0.5 × $25 = $12.50
- Monthly cost: $12.50 × 22 = $275
Monthly Savings
$1,100 − $275 = $825 saved per month
This shows why ChromeDriver is so valuable.
How ChromeDriver Works
ChromeDriver works in the background. It does not have a user interface. Once installed correctly, it quietly controls Chrome when automation tasks run.
The process looks like this:
- Automation tool sends instructions
- ChromeDriver receives instructions
- ChromeDriver controls Chrome
- Chrome performs required actions
Because Chrome changes often, ChromeDriver must stay updated.
Why Chrome Version Matching Is Important
ChromeDriver only works properly when its version matches the major version of the Chrome browser.
Example
- If your Chrome version is 120
- You must download ChromeDriver version 120
If versions do not match, Chrome will not open through automation, and errors may occur.
This is the most common mistake beginners make.
How to Check Your Google Chrome Version
Before you download ChromeDriver, you must know your Chrome version.
You can check it by:
- Opening Chrome
- Going to the settings or help section
- Viewing the version number shown there
Note only the main number, such as 118, 119, or 120.
Understanding the New ChromeDriver Version System
For newer Chrome versions (115 and above), ChromeDriver follows a simplified system:
- One ChromeDriver version supports all minor updates
- Only the main version number matters
This makes downloading easier and reduces confusion.
Where to Download ChromeDriver Safely
Always download ChromeDriver from official sources. This ensures:
- No viruses or malware
- Correct version availability
- Regular updates
- Reliable performance
Avoid third-party websites that promise “all-in-one” downloads, as they may be unsafe.
Download ChromeDriver for Your Operating System
ChromeDriver is available for all major operating systems.
ChromeDriver for Windows
- Download the Windows version
- Extract the file
- Save it in a permanent folder
ChromeDriver for macOS
- Choose the correct version based on your Mac processor
- Extract the file
- Allow system permissions if required
ChromeDriver for Linux
- Download the Linux version
- Extract it
- Set necessary permissions
Setting Up ChromeDriver Properly
After downloading ChromeDriver:
- The file must be placed in a location where your system can find it easily
- This allows automation tools to use it without errors
If ChromeDriver is not set up properly, automation tools will fail to detect it.
How to Confirm ChromeDriver Is Installed Correctly
Once ChromeDriver is set up:
- Automation tools should open Chrome automatically
- No version or path errors should appear
- Chrome should launch smoothly during automation tasks
If Chrome opens without issues, your ChromeDriver setup is successful.
Common Problems While Downloading ChromeDriver
1. Version Mismatch
This happens when Chrome updates automatically but ChromeDriver does not.
Solution: Download the latest matching version.
2. ChromeDriver Not Detected
This happens when the file is placed in the wrong location.
Solution: Move ChromeDriver to a standard system folder.
3. Permission Issues
Common on macOS and Linux systems.
Solution: Allow permissions through system settings.
How ChromeDriver Helps Businesses Save Money
Automation using chromeDriver reduces:
- Manual effort
- Human errors
- Testing time
- Operational costs
Business Cost Example
Manual testing cost:
- Tester cost: $35/hour
- Time spent: 4 hours/day
- Monthly cost:
4 × $35 × 22 = $3,080
Automation cost:
- One-time setup: $500
- Monthly maintenance: $150
Monthly savings:
$3,080 − $150 = $2,930 saved every month
ChromeDriver becomes profitable very quickly.

Yes, ChromeDriver is completely free.
There are:
- No subscription fees
- No licensing costs

- Chrome browser updates
- Automation stops working
- Errors appear suddenly
- New Chrome features are needed
Keeping ChromeDriver updated avoids unnecessary failures.
Best Practices When You Download ChromeDriver
- Always match Chrome’s main version
- Download from official sources only
- Store ChromeDriver in a fixed location
- Update regularly
- Avoid unnecessary multiple versions
Following these steps prevents most issues.
