Open All URLs: Free Multiple URL Opener Online

Use this open all urls tool to launch a whole list of links in separate browser tabs with one click. Paste your URLs separated by new lines, commas, tabs or spaces, choose a delay between tabs, and press Open All URLs. It suits SEO audits, research sessions, QA checks and daily link routines.

What Does It Mean to Open Multiple URLs at Once?

Opening multiple URLs at once means sending a list of web addresses to your browser so each one loads in its own tab, instead of you clicking or typing them one by one. The browser still does the loading. The tool simply hands it the addresses in order.

A valid web address here starts with http:// or https://. If you paste something that looks like a bare domain, such as example.org/blog, the tool adds https:// for you. Entries that are not web addresses, such as a single word or an ftp:// link, are marked invalid and are not opened.

Because every tab is opened by a script and not by your own click, browsers treat the batch as a possible pop-up. That is why the delay setting and your pop-up permissions matter more than any other part of the process.

How to Use the Open All URLs Tool

You can open a full list in under a minute. Follow these steps:

1. Type or paste your links into the URLs box, or press the Paste button to pull them in from your clipboard.
2. Check the counters for Total URLs, Valid, Invalid and Duplicates, and look over the URL Preview list.
3. Tidy the list if needed with Sort A-Z, Remove Dupes, Extract URLs or Clean Invalid.
4. Pick a value in Delay Between Tabs: No delay, 250ms, 500ms, 1 second (the default), 2 seconds, 3 seconds or 5 seconds.
5. Click Open All URLs, or press Ctrl+Enter while your cursor is in the box.
6. If a Popup Blocker Detected message appears, allow pop-ups for this site in your browser settings and run it again. Use Clear to empty the box when you are done.

The Open Log section records what was opened, so you can confirm that every link in the batch was launched.

Worked Example: Cleaning and Opening a Messy List

Say you copied five entries from a spreadsheet and pasted them into the box, one per line:

• https://example.com
• example.org/blog
• https://EXAMPLE.com
• shop.example.net/sale
• hello

The counters would show Total URLs 5, Valid 4, Invalid 1 and Duplicates 1. The second and fourth lines have no protocol, but they look like domains, so they count as valid once https:// is added. The word hello is not a web address, so it is invalid. The third line is flagged as a duplicate because it matches the first one when letter case is ignored.

Click Remove Dupes and Clean Invalid, and you are left with three unique, valid links. With the default 1 second delay, the tabs open about one second apart, which gives each page a head start on loading. Without the cleanup, you would have wasted a tab on a repeated page and hit an error for the invalid entry.

How Do You Read the Counters and Fix Problems?

The four counters tell you whether the list is ready to open. Aim for a Valid count equal to Total URLs and a Duplicates count of zero.

Total URLs and Valid

Total URLs is the number of separate entries the tool found. Valid is how many of them are usable web addresses. If Valid is lower than Total, something in the list is malformed.

Invalid

A nonzero Invalid count turns red. Common causes are a missing dot in the domain, stray text such as a label or number, or a link that uses another protocol. Fix the line by hand, or click Clean Invalid to drop everything that cannot be opened.

Duplicates

A nonzero Duplicates count turns amber. It means the same link appears more than once, even if the capitalization differs. Click Remove Dupes so you do not open the same page twice.

Messy source text

If you pasted a paragraph, an email or an exported report with links buried inside, click Extract URLs to pull out the links, then check the counters. Use Sort A-Z when you want similar domains grouped together so related pages open side by side.

How Do You Open Multiple URLs From Excel, Notepad++ or a Text File?

Copy the links from the source and paste them into the URLs box. Spreadsheet cells in a single column paste as one link per line, and a text file with one link per line works the same way.

• Excel or Google Sheets: select the column of links, copy, then paste. If your links sit across a row, they arrive tab-separated, which the tool also accepts.
• Notepad++ or any text editor: select all, copy and paste. Comma-separated lists work as well.
• Text file: open it, copy the contents, and use the Paste button.

This page runs in your browser tab, so you do not need to install an extension for Chrome, Edge or Firefox. You only need to allow pop-ups for this site once.

Who Uses a Bulk URL Opener?

Anyone who checks the same set of pages repeatedly or needs to review a long list quickly benefits from it. These are the typical situations:

• SEO audits: open a batch of landing pages from a crawl export to check titles, redirects or broken layouts by eye.
• Link and content review: check every page in a backlink report or an outreach list without clicking each one.
• QA and launch checks: open staging or production pages after a deployment and scan each for errors.
• Research: load all the sources for an article or study into one tab group.
• Daily routines: open your dashboards, news sites or social profiles with a single click each morning.

If you are shortening those links for sharing first, the bulk URL shortener handles that step. If your list came from a lead sheet and you also need to verify contacts, try the bulk email validator.

Best Practices, Common Mistakes and Troubleshooting

Most problems come from pop-up blockers and oversized batches. These habits prevent them.

Allow pop-ups before the first run

Browsers often let the first tab through and block the rest. If you see the Popup Blocker Detected message, or only one tab appears, add this site to your browser's allowed pop-ups list and click Open All URLs again.

Choose the right delay

The default of 1 second suits most lists. Use No delay or 250ms for a few lightweight pages. Use 3 or 5 seconds for heavy pages, slower connections or long lists, so your browser is not loading dozens of pages in the same instant.

Start with a small batch

As a general rule, 10 to 20 tabs is comfortable on most computers, and 50 or more can slow down an older machine. Split a 200-link list into groups and open them one group at a time. Close each group of tabs when you finish reviewing.

Check the separators

If the Total URLs count looks too low or too high, look at how the links are divided. A stray space inside a link splits it into two entries, which then show as invalid. Remove the space or fix the line by hand.

Include the full address

Pages that need a specific path, such as example.com/pricing, must include it. A bare domain opens only the homepage.

Remember that sites may need a login

The tool only opens the links. Pages that require an account will show a login screen in your browser unless you are already signed in.

Limitations to Know About

This tool opens only web addresses that start with http or https, so FTP links, email links and other protocols are treated as invalid. It does not check whether a page loads, redirects or returns an error. It reports only whether the text is a well-formed link. You must look at each tab yourself, or use another checker for status codes.

There is no fixed cap on list size in the interface, but your browser and computer set the real limit. Some browsers also cap how many windows or tabs a single action can open, so a very long list may need to be split into smaller runs.

Paste your list into the box above, clear out duplicates and invalid lines, pick a delay and click Open All URLs to get every page into its own tab. For more helpers like this one, browse the online calculators and utilities collection.
