Shortening a URL with LinkShrink takes one API call and zero setup. Send a POST request to https://linkshrink.dev/api/v1/shorten with your long URL in the JSON body. You'll receive a short link, a deletion token, and an analytics endpoint instantly. No signup, no API key, no rate limits — just paste your URL and go. You can also use the playground above to shorten links directly in your browser. For a detailed walkthrough, see our step-by-step guide on how to shorten a URL.

A URL shortener converts long, unwieldy web addresses into compact links that are easier to share, remember, and track. Common use cases include:

• Sharing clean links on social media, SMS, or print materials
• Tracking click-through rates without invasive analytics
• Creating memorable branded links for marketing campaigns
• Embedding short URLs in QR codes for better scan reliability

LinkShrink adds a privacy-first twist: no user tracking, no cookies, and full control over your links with deletion tokens.

Shortened URLs are generally safe, but the safety depends on the shortener service and the destination. LinkShrink prioritizes safety by:

• Validating all destination URLs against known malware and phishing databases
• Supporting the force_preview option so visitors see the destination before being redirected
• Never injecting ads, interstitials, or tracking scripts into redirects
• Providing transparent click analytics without collecting personal data

If you're unsure about a shortened link, append + to the URL (e.g., linkshrink.dev/abc123+) to preview the destination.

No — URL shorteners that use 301 (permanent) redirects pass full link equity to the destination page. LinkShrink uses 301 redirects by default, so search engines treat your short link as equivalent to the original URL. Your destination page keeps all its SEO value. The only scenario where shortened URLs can impact SEO is if the shortener service goes offline, breaking the redirect chain. LinkShrink mitigates this with reliable Azure-hosted infrastructure and 99.9% uptime.

LinkShrink is 100% free with no hidden limits, no premium tiers, and no "freemium" upsells. There is no catch. We don't run ads, sell data, or throttle free users. The service is part of the SoftVoyagers open-source ecosystem and is funded as a developer tool. You get unlimited link creation, click analytics, custom aliases, password protection, QR codes, and full API access — all at zero cost, forever.

Privacy is foundational to LinkShrink, not an afterthought:

• No user tracking — we don't collect IP addresses, browser fingerprints, or personal data
• No cookies — zero cookies are set during redirects or on the website
• Private analytics — enable private_stats to lock click counts behind a secret token only you hold
• Deletion tokens — every link ships with a token to delete it instantly, no account needed
• No third-party scripts — no Google Analytics, no Facebook Pixel, no ad networks

LinkShrink is built for developers and privacy-conscious users who want a no-friction alternative:

• vs Bitly: No signup required, no 10-link free tier limit, no $35/month paywall for basic features. LinkShrink gives you everything Bitly charges for — analytics, custom aliases, QR codes — completely free.
• vs TinyURL: LinkShrink offers a full REST API, deletion tokens, password protection, and private analytics. TinyURL is simple but lacks developer-focused features and has no privacy controls.
• vs both: Zero tracking, open API, no ads, and you can delete any link at any time without an account.

Absolutely. The LinkShrink API is designed for developers and requires no authentication. You can integrate it into any application, script, or workflow by making standard HTTP requests. The API supports JSON request/response bodies and works with every programming language. Features available via API include:

• URL shortening with optional custom aliases
• Click statistics and analytics retrieval
• Link deletion via secure tokens
• Password-protected link creation
• QR code generation for any shortened URL

Check the API documentation for endpoints, examples, and response schemas.

Pass a customAlias field in your API request to choose your own short URL slug. For example, setting "customAlias": "my-launch" creates linkshrink.dev/my-launch. Custom aliases must be 3-50 characters, alphanumeric with hyphens allowed. If the alias is already taken, the API returns a clear error so you can try another. You can also set custom aliases in the interactive playground above.

Yes. Every shortened link can be converted to a QR code by calling the QR endpoint: GET /api/v1/qr/{code}. The QR code is generated as a PNG image that you can embed directly in websites, print materials, or presentations. QR codes are generated on-the-fly with no additional cost or configuration. For advanced QR styling, check out QRMint, another free tool in the SoftVoyagers ecosystem.

Yes. LinkShrink is ideal for marketing campaigns across every channel:

• Social media — clean short links get more clicks and fit character limits on Twitter/X, LinkedIn, and Instagram bios
• Email marketing — short URLs avoid spam filters and broken line wraps in plain-text emails
• SMS campaigns — save characters and reduce SMS costs with compact links
• Print & QR — short URLs are easy to type from flyers and business cards, and each link has a built-in QR code

Combine with UTM parameters to track campaign performance. Use custom aliases like linkshrink.dev/spring-sale for branded, memorable links.

LinkShrink applies a generous rate limit of 100 requests per 15-minute window per IP address. This is more than enough for most use cases, including automated workflows, CI/CD pipelines, and marketing tools. If you hit the limit, the API returns a 429 Too Many Requests response with a Retry-After header indicating when you can resume. There is no paid tier to unlock higher limits — the service is designed to be free and accessible for everyone.
