In short
A URL slug is the readable part of a web address, and generating one means lowercasing the text, replacing spaces with hyphens, stripping accents and removing everything that is not a letter, digit or hyphen. "How to Merge PDF Files in 2026!" becomes how-to-merge-pdf-files-in-2026. Hyphens rather than underscores is the one choice with evidence behind it rather than convention: Google has stated that hyphens are treated as word separators in URLs and underscores are not, so my-page-title is read as three words and my_page_title as one. Accents have to go because a URL is limited to a restricted character set — a URL containing é is percent-encoded into something unreadable, which defeats the purpose of a readable slug. Removing stop words is optional and genuinely debatable: it makes slugs shorter, and it can make them read badly. Two rules that matter more than length. Keep the slug stable, because changing it breaks every existing link unless you redirect. And keep it descriptive, because it is one of the few parts of a URL a person actually reads.

Frequently asked questions
Should slugs use hyphens or underscores?
Hyphens. Google treats a hyphen as a word separator and an underscore as a word joiner, so "merge_pdf_files" can be read as one token while "merge-pdf-files" is read as three words.
How long should a URL slug be?
Short enough to read at a glance — three to six words is typical. There is no ranking penalty for a longer slug, but long URLs get truncated in search results and are harder to share.
Are there any usage caps on the URL Slug Generator?
There is no cost and no cap. The URL Slug Generator is not a demo of a paid product, so nothing is held back or watermarked.
Does anything I enter leave my computer?
No. The URL Slug Generator runs entirely in your browser using JavaScript. Because the work happens locally, the tool also keeps working if your connection drops, and closing the tab is all it takes to discard everything.
Give me a worked example.
Enter "How to Merge PDF Files in 2026!" and the URL Slug Generator returns how-to-merge-pdf-files-in-2026.
When would I actually need the URL Slug Generator?
Typical uses: creating a permalink for a new blog post. Making file names safe for the web. Batch-converting a list of titles into slugs. It is built for exactly those cases rather than being a general-purpose tool with this bolted on.
Is there an app version?
Yes. The page is responsive and the tool works in Chrome, Safari, Firefox, Edge and Samsung Internet on both Android and iOS. There is no app to install and nothing to sign into.
