What is a Bulk URLs?
A Bulk URL Generator is a developer utility that constructs large sets of URLs from a base address and a defined pattern, either a sequential numeric range or a custom list of path segments. Instead of assembling URLs by hand or writing a one-off script, you enter a base URL such as https://example.com/product/, specify a range from 1 to 500, and receive all 500 fully formed URLs instantly.
The core use case is structured URL production at scale. Web properties routinely have hundreds or thousands of pages that follow a predictable pattern: paginated archives (/page/1 through /page/80), product listings (/product/1001 through /product/9999), user profiles (/user/100 through /user/5000), or any set of named paths in a CMS. Constructing these manually is tedious and error-prone. The Bulk URL Generator eliminates that work.
There are two distinct modes. Numbered Range appends consecutive integers between a start and end value to your base URL, covering use cases like pagination, IDs, and any numeric slug pattern. Custom Path List instead accepts free-form path segments, one per line, and combines each with your base URL. This covers the equally common situation where you have a known set of named routes, /about, /contact, /services, and need to convert them all to absolute URLs in one operation.
The output is a clean, copy-ready list of URLs alongside a count. Developers use it to seed crawlers and link checkers, SEOs use it to pre-populate sitemaps (feeding the output into the Sitemap.xml Generator), and QA engineers use it to drive automated testing suites. The generator runs entirely in the browser, no data is sent to any server, and no account or sign-up is required.
Unlike a spreadsheet CONCATENATE formula, this tool requires no knowledge of formulas, handles the base-URL / path join correctly regardless of trailing slashes, and produces output that is ready to use without further formatting.
Why Use a Bulk URL Generator?
The manual alternative to a bulk URL generator is either hand-typing URLs, using spreadsheet formulas, or writing a throwaway script. All three approaches have friction: spreadsheets require formatting care, scripts need a runtime environment, and neither produces output you can copy in a single click.
Crawler and audit seeding is the most direct use case. Tools like Screaming Frog, Ahrefs, and custom Python crawlers accept a list of seed URLs. Generating that list manually for a 200-page site takes minutes of copy-pasting; this generator takes seconds.
Sitemap pre-population is another common workflow. Paste your bulk URL list into the Sitemap.xml Generator to produce valid sitemap.xml output immediately, rather than building the XML by hand or waiting for a CMS plugin to regenerate.
Automated test coverage benefits from numbered range generation. If your end-to-end test suite needs to visit every product page from ID 1 to 1,000, you can generate that seed list here and load it into your test runner without writing a loop in code.
Campaign URL preparation pairs well with the UTM Link Generator, generate the base URL list here, then add tracking parameters to each URL for campaign attribution.
Who Should Use This Generator?
Front-end and back-end developers generating seed data for crawlers, test suites, or load testing tools will find the Numbered Range mode especially useful. Any site with paginated routes or auto-incremented IDs is a natural fit.
SEO professionals and technical SEOs building sitemaps or running crawl audits regularly need bulk URL lists. This tool produces clean output that feeds directly into sitemap builders or desktop crawl tools without intermediate formatting steps. Pair it with the robots.txt Generator to control which URL patterns are exposed to crawlers.
QA and test engineers who write automated browser tests or API tests against paginated or ID-based endpoints can use the numbered range output as fixture data, avoiding the need to hard-code URL lists in test files.
Digital marketers and growth teams preparing bulk campaign URL sets, for instance, generating landing page URLs across multiple variations before applying UTM parameters, benefit from the Custom Path List mode. Input your list of slugs and receive absolute URLs ready for tagging.
Content managers and site administrators who periodically audit large sites or need to compile a URL inventory for redirects, canonical checks, or migration planning can export path slugs from their CMS and convert them to full URLs here in one step.
What Insights Does the Bulk URLs Generator Give You?
The Bulk URL Generator produces two outputs, both immediately actionable.
Generated URLs is the primary output, a code-formatted list where each line is a complete, fully formed URL. Every URL is constructed by concatenating your base URL with the appropriate path segment (number or custom string). The output is plain text, one URL per line, which is the standard input format for sitemap builders, crawlers, link validators, and test runners. The exact formatting matters: the list requires no cleanup before use.
URL Count shows the total number of URLs in the generated list. This is useful as a quick sanity check before copying, if you expected 100 URLs but the count shows 99, you know your start/end range is off by one. It also helps when you need to report the scope of an audit or confirm that your CMS slug export matched expectations.
Together, the outputs answer two questions: what are the exact URLs, and how many are there? For most dev and SEO workflows, these two pieces of information are everything needed to proceed to the next step, crawling, sitemap generation, or testing.
How to use this Bulk URLs calculator
Enter your Base URL. In the Base URL field, type or paste the common prefix shared by all URLs you want to generate, for example,
https://example.com/product/. Include the trailing slash if your URL pattern requires it.Select a Mode. Use the Mode dropdown to choose between Numbered Range and Custom Path List. Select Numbered Range if your URLs follow a sequential integer pattern. Select Custom Path List if you have a set of specific named paths.
For Numbered Range: Set the Start Number (the first integer to append) and the End Number (the last integer). For example, Start 1 and End 50 generates 50 URLs:
.../product/1through.../product/50. The Start Number must be less than or equal to the End Number.For Custom Path List: Enter your path segments in the Paths (one per line) field, one segment per line, without a leading slash unless you need one. For example, entering
about,contact, andserviceswith base URLhttps://example.com/produceshttps://example.com/about,https://example.com/contact, andhttps://example.com/services.Generate the list. The output appears in the Generated URLs panel, with one URL per line. The URL Count field shows the total. Review the count to confirm it matches your expectation before copying.
Copy and use the output. Use the copy button above the Generated URLs panel to copy the entire list to your clipboard. Paste it directly into a crawler, the Sitemap.xml Generator, a spreadsheet, or a test fixture file.

Formula & Methodology
The Bulk URL Generator applies straightforward string concatenation, no encoding transformation or URL normalisation beyond what you explicitly provide. Numbered Range mode:URL[i] = baseUrl + iwhereiiterates fromstarttoendinclusive. The total count isend − start + 1. Example: Base URL =https://example.com/page/, Start = 1, End = 5https://example.com/page/1 https://example.com/page/2 https://example.com/page/3 https://example.com/page/4 https://example.com/page/5URL Count: 5 Custom Path List mode:URL[i] = baseUrl + paths[i]wherepathsis the array of lines from the Paths field, with blank lines excluded. Example: Base URL =https://example.com/, Paths =about,contact,faqhttps://example.com/about https://example.com/contact https://example.com/faqURL Count: 3 Joining behaviour: The tool performs literal concatenation. If your base URL ends with/and your path segment does not start with/, the join is clean:https://example.com/+about→https://example.com/about. If both have a slash, you will get a double slash:https://example.com/+/about→https://example.com//about. Ensure your base URL and paths are consistent to avoid this. The generator does not silently normalise double slashes because doing so would mask a misconfiguration that you want to know about before using the list. No HTTP requests are made at any point. The generator is a pure string-construction function that runs in your browser.
