How to Shorten a URL: Step-by-Step Guide for Any Device

Shortening a URL takes under 30 seconds using any web-based shortener. This guide covers four ways to do it — via the web, on mobile, programmatically via API, and with a custom alias — so you can pick whichever fits your workflow.

Method 1: Web shortener (fastest, no setup)

1. Open shortfy.co in any browser.
2. Paste your long URL into the input field on the homepage.
3. Click Shorten (or press Enter).
4. Your short link appears instantly — copy it with the Copy button.
5. Share the short link anywhere: email, social, SMS, print.

Method 2: Custom alias (more memorable)

Instead of a random slug like /4kX9m, you can choose a custom alias like/my-event or /shop — ideal for links you will mention in a video, print on a flyer, or share in a bio.

1. Sign in to your Shortfy account.
2. Paste your URL and expand the Custom alias field.
3. Type your preferred alias (letters, numbers, and hyphens only).
4. If the alias is available, the link is created immediately.

Method 3: Mobile (iPhone and Android)

1. Navigate to the page you want to shorten.
2. Tap the address bar and copy the URL.
3. Open a new tab and go to shortfy.co.
4. Paste the URL and tap Shorten.
5. Tap Copy and paste the short link wherever you need it.

Add shortfy.co to your home screen as a bookmark for one-tap access when you shorten links frequently on mobile.

Method 4: API (for developers)

If you need to shorten URLs programmatically — from a script, app, or automation — Shortfy's REST API handles it in a single POST request:

Send { "url": "https://your-long-url.com" } in the request body and receive the short URL in the response. The API is free to use (rate-limited on the free plan). Full documentation at shortfy.co/docs.

Common mistakes to avoid

• Shortening a short link. If you paste an existing short link into a shortener and shorten it again, you create a double redirect — slower and harder to track. Always shorten the original, full URL.
• Reusing one link for every channel. Create separate short links for email, Instagram, and LinkedIn so you can compare performance by channel. A single link shows only totals, not attribution.
• Not testing before sending. Click your short link yourself before including it in an email campaign or printed material. Confirm the redirect lands on the correct destination.
• Forgetting about expiry. If you set a link expiry date, remove or update any references before it expires — broken short links in print or video content cannot be fixed retroactively.

Can you shorten any URL?

Almost any publicly accessible URL can be shortened. Exceptions: URLs blocked by the shortener's spam or malware filter (shorteners screen destinations to prevent abuse), internal network addresses that are not publicly reachable, and already-short URLs (no meaningful gain).
