Multiline Slug Generator

Q: How many lines can I convert at once?

There is no hard limit on the number of lines you can convert. The tool processes all lines in real-time in your browser. For optimal performance, we recommend processing up to a few hundred lines at a time. If you have a very large list, you can split it into batches.

Q: Can I copy all slugs at once?

Yes! Click the 'Copy All Slugs' button to copy all generated slugs to your clipboard, one per line. This makes it easy to paste them into spreadsheets, CMS platforms, or any other tool. You can also copy individual slugs by clicking the copy button next to each one.

Q: What happens to empty lines in my input?

Empty lines in your input are automatically skipped during slug generation. Only lines containing actual text will produce a slug. This means you can freely use blank lines to separate groups of titles in your input without affecting the output. The tool also tells you how many blank lines it skipped so the count is never a surprise.

Q: Why do two of my slugs come out identical?

Two different titles can collapse to the same slug — for example 'The Best Coffee!' and 'the-best coffee' both become 'the-best-coffee'. Because a slug is meant to be a unique URL, identical slugs would clash: only one page can live at that address. This tool detects and counts these duplicate collisions for you so you can rename a title or add a distinguishing word before the clash reaches your CMS.

Q: Will the same options apply to every line?

Yes. Whatever options you set — separator type, lowercase, remove numbers, remove stop words, or length limit — are applied uniformly to every line in the batch. This guarantees a consistent slug style across an entire list of titles, which is exactly what you want when generating URLs for a whole section of a site at once.

Q: Does this share settings with the single Slugify tool?

Yes. This bulk tool uses the same slug logic and reads the same saved options as the parent Slugify tool, so a slug you preview for one title there will match the slug produced here. Switch between them freely without worrying about getting different results for the same text.

Convert multiple lines of text into URL slugs at once. Paste a list of titles, headings, or phrases and get all slugs generated instantly — one per line.

What It Does

A slug is the readable, hyphenated part of a URL — the "how-to-learn-javascript" in /blog/how-to-learn-javascript. This tool takes a whole list of titles, headings or phrases, one per line, and turns every line into a clean slug in a single pass, applying the same options to all of them. Doing it in bulk matters because consistency is the point: when an entire blog section, sitemap or category tree shares one slug style, links stay predictable and nothing breaks. Just as important, generating slugs together lets the tool spot duplicate collisions — two titles that produce the identical slug and would fight over the same URL — which you would never notice converting them one at a time.

When to Use It

You exported a CSV of article titles from your CMS and need a matching slug for every row before bulk-importing the posts.
You are building a sitemap or URL map for a new site section and want every page path generated in one consistent style.
You have a list of product or blog category names and need SEO-friendly URL paths for each without hand-typing them.
You are migrating content to a new platform and must produce stable, predictable slugs for hundreds of existing pages at once.

Worked Examples

My First Blog Post
How to Learn JavaScript in 2024
10 Tips for Better Web Design

Three ordinary titles become three slugs in one pass: my-first-blog-post, how-to-learn-javascript-in-2024 and 10-tips-for-better-web-design. Every line gets the exact same separator and casing, so the batch is consistent end to end.

The Best Coffee!
the best coffee
The  Best   Coffee

All three lines collapse to the same slug, the-best-coffee. The tool flags this as a duplicate collision — only one page can own that URL, so you would need to rename two of these titles before publishing.

Getting Started

Advanced Topics


Wrap Up

The blank separator lines between the three real titles are skipped, producing getting-started, advanced-topics and wrap-up. The tool reports how many blank lines it ignored so you can confirm nothing real was lost.

How to Use

1. Enter or paste multiple lines of text in the input area (one title/phrase per line). 2. Slugs are generated in real-time for all lines. 3. Adjust options: separator type, lowercase, remove numbers, remove stop words, or limit length. 4. Review the insight panel for the slug count, any duplicate collisions, and skipped blank lines. 5. Click 'Copy All' to copy all slugs at once, or copy individual slugs. 6. Click 'Clear' to reset everything.

Common Mistakes

Assuming every title yields a unique slug. Two different titles can collapse to the identical slug and clash as URLs — watch the duplicate count and rename or distinguish the offenders before importing.
Ignoring blank lines in the paste. Empty or whitespace-only lines are silently skipped, so if your output count is lower than expected, blank lines (not lost titles) are usually the reason — the tool tells you how many were skipped.
Pasting an enormous list in one go. Processing many thousands of lines at once can briefly freeze the browser tab; split very long lists into batches of a few hundred for a smoother experience.
Changing options after copying. The same options apply to all lines, but if you tweak a setting after copying, the clipboard still holds the old batch — copy again after any change so your slugs match the current settings.
