Free link and QR code tools

Nothing is a trial, and nothing asks for a credit card. Create an account only when you want click analytics, editable destinations, or custom slugs.

There are six tools and 20 focused variants. If you're not sure where to start: shorten a URL, then turn it into a QR code.

Shorten links

URL shortener — Paste any link, get a short in.bio address instantly. Custom slugs, optional expiry, and a QR code for every link. Start here if you just need one short link.

Bulk URL shortener — Paste up to 50 URLs at once and get them all back as short links with a CSV export. Built for print runs, product catalogues, and campaign launches where you need dozens of codes in one sitting.

Shorten links for a specific platform

Each of these covers how that platform actually handles links — character limits, whether it re-wraps your URL, what breaks, and what to do about it:

• Instagram — one bio link, unforgiving captions, and how to track what your profile actually drives
• TikTok — bio links, link stickers, and the follower thresholds that gate them
• YouTube — descriptions, cards, and timestamped links
• Twitter / X — what t.co does to your link and why you still want your own in front of it
• LinkedIn — lnkd.in re-wraps your links and gives you no analytics; this is the way around it
• Facebook — posts, bios, and how preview crawlers affect your click counts
• Google — Docs, Drive, Maps and Forms links, which are among the longest URLs on the web. Also home to gogl.ink
• Amazon — product links carry tracking cruft; here's what's safe to strip
• Spotify — what the ?si= parameter on your share link means, plus sptfy.app
• Canva — design and template share links
• Microsoft — SharePoint, OneDrive and Teams links, the worst offenders for length
• Adobe — Creative Cloud and Acrobat share links

Generate QR codes

QR code generator — Build a QR code for any URL, style the dots and corner markers, set your brand colours, and download PNG or SVG. Every design is machine-verified as scannable before you download it.

QR codes that do something other than open a URL

A QR code can carry more than a web address. Each of these encodes a different data type, so the scan triggers the right action on the phone automatically:

• Wi-Fi — guests connect to your network by scanning, no password typing. SSID, password and security type
• vCard — a full contact card that saves straight to the phone's address book. For business cards and trade-show badges
• Email — opens a pre-addressed email with your subject and body already filled in
• Phone — scanning starts a call to your number
• SMS — opens a text message with the number and message pre-written. Useful for keyword campaigns
• WhatsApp — starts a WhatsApp chat with a pre-filled first message
• Text — displays plain text on scan, with no internet needed. For instructions, serial numbers, and equipment labels
• Crypto — a wallet address and amount in the format wallet apps expect

Tag and measure campaigns

UTM builder — Build properly tagged campaign URLs without hand-editing query strings. Consistent casing and naming, so one campaign doesn't splinter into a dozen rows in your reports.

Check links before you open them

Link safety checker — Paste any link and see its real destination, a malware/phishing verdict, the domain's age, HTTPS status, and lookalike-domain detection. The safe way to answer "is this link safe?" before clicking.

Link expander — Paste a short link and see exactly where it goes by following every redirect on our server — nothing loads on your device.

Everything here has an API — free, no key

Every tool on this page is also one HTTP request away. No account, no API key, no OAuth dance:

curl -X POST https://in.bio/api/shorten \
  -H "Content-Type: application/json" \
  -d '{"url":"https://example.com"}'

QR codes are a single GET:

curl "https://in.bio/api/qr?url=https://example.com&format=svg"

There are official SDKs for JavaScript, Python, PHP, Ruby and Go, and an MCP server at mcp.in.bio if you want an AI agent to create and track links for you directly. Full reference in the API docs.
