LinkedIn Job Search URL Builder

A browser-based tool for building custom LinkedIn job search URLs with bulk company filters and advanced parameters. Skip the tedious one-by-one company dropdown — paste IDs in bulk and go.

Zero dependencies. Single HTML file. Runs offline. Works on mobile.

100% private — this tool runs entirely in your browser. No data is sent to any server. No analytics, no cookies, no tracking.

Why?

LinkedIn's job search lets you filter by company, but adding companies one at a time through the dropdown is painfully slow — especially if you're targeting 20, 50, or 100+ companies in a specific industry.

Under the hood, LinkedIn stores company filters as numeric IDs in the URL parameter f_C. This tool lets you:

• Bulk-add company IDs instead of selecting them one by one
• Combine all LinkedIn search parameters into a single bookmarkable URL
• Export/import company lists as JSON to share with others
• Persist everything in localStorage so your setup survives browser restarts

How to Find LinkedIn Company IDs

Option A: From the company filter (fastest)

1. Go to LinkedIn Jobs
2. Type a company name into the Company filter dropdown
3. Select it, then copy the number after f_C= in the URL

Option B: From the company page

1. Visit the company's LinkedIn page
2. Click "See all jobs" or "See all employees"
3. The ID appears after f_C= or currentCompany= in the URL

Option C: Verify an ID

Visit linkedin.com/company/[ID] — it redirects to the company page.
