How to Extract Emails, Phones and WhatsApp From a Website for Free

Contact Finder by LeadTrapper is a free Chrome extension that extracts the contact details a business publishes on its own website: email addresses, phone numbers, WhatsApp numbers, addresses and social media profiles. Open the site, click the icon, and it lists what it found, checking the site’s Contact, Team and Branches pages for you. You can then download everything to Excel or CSV.

What Contact Finder Extracts

When you click the icon on a business website, Contact Finder reads that site and a few of its own pages where contact details usually sit, such as Contact, Team, About and Branches. It then lists five kinds of contact:

• Emails, including addresses a site hides from simple copy-paste.
• Phone numbers, in international format, with the country worked out from the website.
• WhatsApp numbers, taken from chat buttons and WhatsApp links.
• Addresses of offices and branches, each with a map link.
• Social media profiles, with their handles.

It also leaves out what is not a contact: no-reply addresses, image file names, dates, fax numbers and share buttons.

How to Use It

Install Contact Finder from the Chrome Web Store and pin it to the toolbar: click the puzzle icon at the top right of Chrome, then the pin next to Contact Finder.

1. Open the website of a business, for example a clinic, a restaurant or a supplier.
2. Click the Contact Finder icon. It shows how many pages of the site it checked and lists the contacts by type.
3. Tick the contacts you want and press Add to my list.
4. Open the next website and click the icon again. Your list keeps growing.
5. Press Download my list and choose Excel or CSV.

What We Found in a Real Test

On 13 October 2026 we ran Contact Finder on the websites of five dental and aesthetic clinics in Dubai, chosen from a Google Maps search. We clicked the icon once on each home page and recorded what it listed. We are not naming the clinics or repeating their details here.

Four of the five sites returned contact details, 31 in all. Clinic 1 lists two branches, and Contact Finder gave each phone number and address the name of its branch. Social profiles were the most common find and emails the rarest. That matches our Google Maps scans, where only 15% to 47% of businesses had an email on their website.

Clinic 5 returned nothing: Contact Finder checked one page and found no contact details in it. In that case the popup suggests opening the site’s Contact page and trying again, which is the right next step. This was five websites in one city on one day, so it shows what to expect, not a success rate.

Who Each Contact Belongs To

Business websites often list several addresses: a general inbox, a booking desk, team members and branches. Contact Finder labels each contact as a general inbox, a department, a person (with their name when the page shows it) or a branch (with the branch name), and shows which page it came from.

The label comes from the nearest heading or name on the page, so it is only as tidy as the website. In our test a few labels were the day of the week the clinic printed next to its number. Read the label as a hint about where the contact sits, and check the page when it matters.

Export to Excel or CSV

Download my list saves every contact you added, from every website, in one file. You choose:

• Excel, which opens directly with each contact on its own row.
• CSV, for importing into a CRM or a spreadsheet tool.
• Phone numbers only (send-ready), a clean list of numbers for messaging.

The list stays in your browser until you press Clear, so you can collect over several sessions.

What It Does Not Do

• It works on business websites only. It refuses search engines and social networks, such as Google, Google Maps, LinkedIn, Facebook, Instagram, TikTok and X.
• It reads one website at a time, and only when you click its icon. It does not crawl a list of sites in the background.
• It reads what the website publishes. If a site shows no email, there is no email to find, and it does not guess addresses.
• It runs in Chrome on a computer. Browser extensions cannot be installed on a phone.

Free Extension, Cloud Scraper or Desktop App?

Searches for a contact details scraper mostly turn up cloud services that crawl a list of websites for you and charge by usage, which suits developers and large one-off jobs. A free extension suits checking businesses one by one as you research them. The LeadTrapper Windows app sits in between for sales work.

The app’s Website Contact Finder, under Google Maps in its left menu, uses the same rules as the extension. Give it your own list of websites, or a business type and a city, and it reads each site’s home page and its contact, team and branch pages.

Getting Contact Numbers for Marketing

Finding a number is the first step. Before you message anyone, two things decide whether it works. First, check which numbers are actually on WhatsApp, so you do not waste messages; the WhatsApp Number Filter guide shows how. Second, keep to WhatsApp’s rules on unsolicited messages, which the cold outreach policy guide explains.

If your leads come from Google Maps rather than websites, the free Maps Lead Extractor reads a results page, and the Google Maps scraper in the Windows app collects whole areas with phone numbers and websites. Use the contacts you collect lawfully and follow the anti-spam and privacy rules of the places you contact.
