🗂️ URL Opener: Open Multiple URLs at Once
By Shihab Mia · Updated 2026-07-01
Paste a list of web addresses, one per line, and this URL opener launches every one of them in a new browser tab with a single click. Before it opens anything it cleans your list for you: it can add https:// to bare domains like example.com, remove duplicate links so the same page does not open twice, and reverse the order if you want the last link on top. It also shows every cleaned link as a clickable list you can open one by one, which is a reliable fallback when the browser blocks a burst of popups. Everything runs in your browser, so your links are never uploaded or stored.
What is the URL Opener (Open Multiple URLs)?
Opening a dozen tabs by copying and pasting each address into the address bar is slow and repetitive. A URL opener does it in one step: it reads your pasted list, treats each non-empty line as one address, applies a few cleanup options, and then calls the browser to open each one in a new tab. The heavy lifting is in the cleanup, because a raw paste is usually messy: blank lines, trailing spaces, the same link twice, and bare domains with no https:// in front.
The "Add https:// to bare domains" option looks at each line and, if it has no scheme (no https://, http:// or similar) but still looks like a real host such as shop.example.com/deals, it prepends https:// so the link actually opens instead of being treated as a search. Lines that already start with a scheme are left untouched, and text that does not look like a domain is left exactly as pasted so nothing is silently mangled.
"Remove duplicates" compares links case-insensitively and keeps only the first time each one appears, so a list with the same page pasted three times opens that page once. "Reverse order" flips the final list, which is handy when your newest or most important link sits at the bottom and you want it to open first. The counters show how many lines you pasted, how many links are ready to open, and how many were cleaned out, so you can see exactly what will happen before you click.
Actually opening many tabs is where browsers push back. To stop abusive pages, every modern browser blocks a page from opening more than one or two popups per click unless you have allowed it. That is why this tool also renders each cleaned link as a normal clickable anchor with target="_blank" and rel="noopener": those always work, one click at a time, even when the bulk Open all button is blocked. If Open all is blocked, allow popups for this site once and it will work every time after.
When to use it
- Opening a batch of research links, product pages or articles all at once instead of one by one.
- Reopening a saved set of dashboards, tools or work URLs at the start of your day.
- QA and testing: launching a list of staging or production pages to eyeball them quickly.
- SEO and outreach: opening a list of prospect sites, competitor pages or backlinks to review.
- Turning a messy paste of links into a clean, deduplicated list before opening or sharing it.
- Cleaning up a bare-domain list (example.com, example.org) into working https:// links.
How to use the URL Opener (Open Multiple URLs)
- Paste your URLs into the box, one link per line. Blank lines are ignored.
- Tick "Add https:// to bare domains" so links like example.com open correctly.
- Tick "Remove duplicates" to open each page once, and "Reverse order" if needed.
- Press "Open all" to launch every cleaned link in a new tab.
- If a popup was blocked, allow popups for this site, or click the fallback links below one at a time. Use "Copy list" to grab the clean list.
Formula & method
Worked examples
You paste four lines: "example.com", "https://example.com", a blank line, and "wikipedia.org", with Add https and Remove duplicates both on.
- The blank line is dropped, leaving three links to consider
- example.com has no scheme and looks like a host, so it becomes https://example.com
- wikipedia.org becomes https://wikipedia.org the same way
- Now the list is https://example.com, https://example.com, https://wikipedia.org
- Remove duplicates keeps the first https://example.com and drops the second
Result: 2 links ready to open: https://example.com and https://wikipedia.org, 1 cleaned out.
You paste three working links in order A, B, C and turn on Reverse order (duplicates off).
- All three already start with https://, so nothing is added
- Remove duplicates is off, so all three are kept
- Reverse order flips the list from A, B, C to C, B, A
- Ready to open shows 3
- Pressing Open all opens C first, then B, then A, each in a new tab
Result: 3 links ready, opened in reverse order C, B, A.
How each option changes your list
| Option | What it does | Example |
|---|---|---|
| Add https:// to bare domains | Prepends https:// to scheme-less hosts | example.com to https://example.com |
| Remove duplicates | Keeps the first of each repeated link (case-insensitive) | Two identical links become one |
| Reverse order | Flips the final list top to bottom | A, B, C becomes C, B, A |
| (none) | Only trims spaces and drops blank lines | Clean list in original order |
What gets an https:// prefix and what does not
| Pasted line | Add https on? | Result |
|---|---|---|
| example.com | Yes | https://example.com |
| shop.example.com/deals | Yes | https://shop.example.com/deals |
| http://example.com | Yes | http://example.com (already has a scheme) |
| just some text | Yes | just some text (not a domain, left as is) |
| example.com | No | example.com (left as pasted) |
Common mistakes to avoid
- Expecting all tabs to open when popups are blocked. Browsers block a page from opening many tabs from one click. If only one tab opens, look for a blocked-popup icon in the address bar, choose to always allow popups for this site, then press Open all again. The clickable fallback links always work one at a time.
- Leaving bare domains without a scheme. A line like example.com with Add https turned off may be treated as a search term or fail to open. Turn on "Add https:// to bare domains" so scheme-less hosts become real https:// links.
- Pasting multiple links on one line. This tool reads one URL per line. If you paste several links separated by spaces or commas on a single line, put each on its own line first so every link is opened.
- Assuming duplicates are matched exactly. Remove duplicates compares links case-insensitively, so HTTPS://Example.com and https://example.com count as the same. If you truly need both variants, turn duplicate removal off.
Glossary
- URL
- Uniform Resource Locator, the full web address of a page, such as https://example.com/pricing.
- Scheme
- The prefix that says how to reach a URL, for example https:// or http://.
- Bare domain
- A host written without a scheme, such as example.com, which needs https:// added to open reliably.
- Popup blocker
- A browser feature that stops a page opening more than one or two new tabs or windows per click unless you allow it.
- New tab (target _blank)
- Opening a link in a separate tab so your current page stays put; this tool uses it for every link.
- rel="noopener"
- A safety attribute that stops a newly opened tab from gaining scripting access back to the page that opened it.
Frequently asked questions
How do I open multiple URLs at once?
Paste your links into the box, one per line, then press Open all. The tool cleans the list (optionally adding https, removing duplicates and reversing order) and calls the browser to open each link in a new tab. If your browser blocks the burst of popups, allow popups for this site and press Open all again, or click the fallback links below one at a time.
Why does only one tab open when I click Open all?
Modern browsers block a page from opening many tabs from a single click to prevent abuse. This is not a bug in the tool. Find the blocked-popup icon in your address bar, choose to always allow popups for this site, then press Open all again and every tab will open.
Does it add https:// to links that are missing it?
Yes, when "Add https:// to bare domains" is ticked. Any line that has no scheme but looks like a real host, such as example.com or shop.example.com/deals, gets https:// added so it opens as a webpage instead of a search. Lines that already start with http:// or https:// are left untouched.
Will it open the same link twice?
Not if "Remove duplicates" is on, which it is by default. The tool compares links case-insensitively and keeps only the first occurrence, so a page pasted several times opens once. Turn the option off if you deliberately want every repeated line opened.
Are my links sent to a server?
No. All parsing, cleaning and opening happens in your browser with plain JavaScript. Your list is never uploaded, logged or stored, so it is safe to use with private or internal URLs.
Can I copy the cleaned list instead of opening it?
Yes. Press "Copy list" to put the cleaned, deduplicated links on your clipboard, one per line, ready to paste into a document, spreadsheet or another tool. The copy uses the same cleanup options you have selected.
