Free URL Shortener — Custom Aliases, UTM Builder & Analytics

1. Paste your destination URL into the input field (or switch to bulk mode and paste multiple URLs, one per line).
2. Optional: type a custom alias (3–20 letters, numbers, hyphens, or underscores) — leave blank for an auto-generated code.
3. Optional: toggle UTM Tracking and fill in source/medium/campaign (term and content are optional) to preserve attribution through the redirect.
4. Optional: set an expiration preset (1 minute to 365 days) or a custom date/time, and toggle password protection if the link should require unlocking.
5. Click Shorten, then copy the fyntools.com/s/{code} link or click the QR icon to download a scannable code.
6. Open /s/{code}/stats at any time to check click totals for that specific link.

Most free shorteners hand you a random six-character code and stop there. FYN Tools’ URL Shortener adds the controls a real campaign needs in one form: a custom alias so the link reads /s/spring-sale instead of /s/x7Kq2, a five-field UTM builder (source, medium, campaign, term, content) that gets appended before the code is created, an optional password gate, and expiry presets from one minute to one year.

The alias field is validated client-side against a strict pattern — 3 to 20 characters, letters, numbers, hyphens, or underscores — so you get instant feedback instead of a server round-trip rejection. Bulk mode accepts one URL per line and returns a result row per line, including per-row errors if a specific alias collides.

A shortened link is a database row: short code → destination URL, plus optional metadata (UTM string, password hash, expiry timestamp, click counter). When a visitor opens /s/{code}, FYN Tools looks up the row, checks expiry and password, increments the click counter, and redirects. Nothing about the destination page changes — the shortener is a lookup layer in front of it.

How it works

Type or paste your destination URL. If you enable UTM tracking, five inputs (source, medium, campaign, term, content) get serialized into a query string appended to the destination before the short code is generated — so the link you eventually click still carries full attribution. Choose an expiration preset (1 minute up to 365 days) or leave it unset for a permanent link. Enabling the password toggle requires visitors to unlock the redirect before it fires. Submitting the form returns your short URL immediately; the QR icon renders a scannable code from that exact short link.

Need a scannable code instead of a link? Use our QR Code Generator.

• Social media sharing: Turn long tracking or product URLs into compact links that are easier to paste into posts, messages, and profiles.
• UTM campaign links: Add campaign parameters before shortening so marketing links remain compact while retaining the tracking values your analytics setup expects.
• Temporary campaign links: Use an expiration date for links created for events, promotions, or limited-time campaigns instead of leaving them active indefinitely.
• Bulk link preparation: Paste multiple URLs at once when preparing a spreadsheet, content calendar, campaign list, or set of links for a team.
• QR code for print: Generate a QR code from the shortened URL when the destination needs to be shared on posters, cards, packaging, or other printed material.
