Sign up & sign in

lnk.tj is a short-link service with analytics, teams and plans. Create an account in a minute — no card for the free plan.

1. On the home page click “Get started” or “Start for free”.
2. Enter your name, email and a password (6+ chars) — you'll land in the dashboard on the “Free” plan.
3. To sign in later, use “Sign in” in the header.

Demo logins: user@link.tj / user123 (user), admin@link.tj / admin123 (superadmin).

Dashboard overview

The main screen shows your monthly usage, the link-creation form and a clicks chart. On the left — navigation and the workspace switcher.

1. The “Links this month” and “Clicks” bars show what's left on your plan.
2. If you're near a limit, a hint to upgrade appears.
3. The “Workspace” switcher (top left) changes context: personal account or company.

Dark and light theme

The interface supports a dark theme. The toggle (☀️/🌙) is in the site header and the dashboard; your choice is remembered.

1. Click the theme icon in the header.
2. The theme switches instantly and is saved for next visits.

Creating a short link

You can shorten a link right on the Overview. The slug (link tail) is generated automatically or set manually.

1. Paste a long URL into the “Target URL” field.
2. Optionally set a “Title” and your own slug (e.g. promo).
3. Click “+ Advanced” to set tags, expiry, click limit and a password.
4. Click “Shorten” — the short link appears with a “Copy” button.

Custom slugs and bulk creation are on paid plans. There you'll also see type tabs above the form — Wi-Fi, vCard and text (see “Link types”).

Link list, search and folders

“My links” shows all your links with clicks, status, tags and folders. There's search and filters.

1. Search by slug, title or URL.
2. Filter by tags (#promo) or folders.
3. Create a folder with “+ folder” and organize links.
4. “Details” opens the link page; “Copy” copies the short URL.

Link page: editing, QR, analytics

The link page has full analytics, a QR code and an editor for every parameter.

1. Change the destination URL, title, tags, folder, expiry and click limit.
2. Set or remove a link password.
3. Style the QR in the designer (pattern, color, logo — see “QR design”) and download SVG/PNG.
4. View clicks by time, country, device and source.

You can temporarily disable a link with “Disable” without deleting it.

QR code design

The link page has a QR designer: change the pattern, eye (corner) shape, color or gradient, add a logo, a “SCAN ME” frame and a background — the preview updates instantly and exactly matches the downloaded file.

1. Module pattern: squares, rounded, extra-rounded, dots, “classy” and “classy+”.
2. Corners (finder marks): square, rounded, extra or round.
3. Color from the palette, or a gradient (linear/radial) with two colors.
4. Center logo: drop a file (PNG/JPEG/WebP/SVG, up to ~24 KB) — error correction is raised to maximum automatically.
5. Transparent background, “SCAN ME” frame, error-correction level (L/M/Q/H).
6. Download SVG or PNG, or “Copy” — the QR goes to the clipboard.

QR design is on paid plans. Patterns and gradients can affect readability — test the code with a phone before printing.

Link types: link, Wi-Fi, vCard, text

Besides a regular short link you can create a QR for connecting to Wi-Fi, a contact card (vCard) or arbitrary text. Pick the type with the tabs above the form when creating.

1. Wi-Fi — network name, encryption and password. The opened page shows the details and a QR to connect by camera.
2. Contact (vCard) — name, phone, email, company, etc. The visitor taps “Save contact” and gets a .vcf file.
3. Text — any text the recipient sees and can copy.
4. A dynamic QR (default) goes through our domain — clicks are tracked and the destination can be changed.
5. A static QR (offline) encodes the data directly — works without internet, but without analytics.

Wi-Fi/vCard/text types are on paid plans. Such links can also be password-protected — the password is asked before the page is shown.

PRO link controls

Each link can have restrictions and protection — at creation (the “Advanced” section) or on the link page.

1. Expiry — the link stops working after a date.
2. Click limit — the link closes after N visits.
3. Password — the visitor sees a password page before redirecting.
4. Tags and folders — for easy organization.

Bulk shortening

On “Growth” and higher you can shorten a list of links in one go.

1. Open “Bulk shortening”.
2. Paste URLs one per line (up to 200).
3. Optionally set shared tags and click “Shorten all”.
4. Copy the ready short links with “Copy all”.

Custom domains

On “Growth” and higher you can brand links with your own domain (e.g. go.company.com).

1. Open “Domains” and add a domain.
2. Add the listed DNS records (CNAME and TXT) at your registrar.
3. Click “Verify” — once confirmed, the domain can be used in links.

Click analytics

Detailed stats for all your links: unique/repeat clicks, bots filtered out.

1. See click trends, a world map by country and cities.
2. Analyze traffic sources, UTM campaigns, devices, browsers and language.
3. Activity by hour and weekday hints at the best time to post.

History retention depends on your plan (30 days — 3 years).

Company and employees

The corporate plan is one subscription for the whole company. The company admin adds employees; limits are shared.

1. Switch to the corporate plan — a company is created and you become its admin.
2. In “Team”, add employees (name, email, password).
3. Set each a personal monthly link limit if needed.
4. Switch between your personal account and the company in “Workspace”.

One user can belong to several companies and have a personal account at the same time.

Plans, promo codes, annual billing

Pick a plan for your link volume. Monthly or yearly (−20%). Promo codes are supported.

1. Open “Pricing” and toggle the “Month/Year” period.
2. Enter a promo code to see the discount.
3. Click to choose a plan — the first payment asks to add a card.

Billing and invoices

“Billing” shows the current subscription, next charge date, card and invoice history.

1. Add/remove a card in “Payment method”.
2. Download invoices or export history to CSV.
3. “Cancel plan” moves you to “Free”.

Employees aren't asked to pay — the company admin pays.

API keys and documentation

Manage short links programmatically. Create a key and use the REST API.

1. In “API keys”, create a key (shown once — copy it).
2. Send it in the header Authorization: Bearer <key>.
3. Create plain links or types (kind=wifi/vcard/text + payload) — types need a paid plan.
4. Full endpoint reference and examples are on the “API documentation” page.

Profile, password and 2FA

“Settings” — change your name, email, password, two-factor authentication and sign out everywhere.

1. Change name/email/password (email and password need your current password).
2. Enable 2FA: scan the QR in an authenticator app and confirm with a code.
3. “Sign out everywhere” ends all other sessions.

Report a link

Anyone can report a malicious or fraudulent short link — without signing in.

1. Open /report (the link is in the site footer).
2. Paste the link, pick a reason and describe the problem.
3. Submit — moderators are notified and review the report.
