# Short URL + UTM + QR Bundle Builder One pass replaces bit.ly + Campaign URL Builder + QR generator: GA4-validated UTM parameters, a deterministic self-hosted short link (FNV-1a base62 slug), QR pair, redirect snippets and a tracking CSV row. > Canonical page: https://elysiatools.com/en/tools/short-url-utm-builder-qr-bundle - **Category:** Utilities - **Keywords:** utm, short link, qr code, campaign url builder, ga4, self-hosted shortener ## Overview GA4 requires utm_source/utm_medium/utm_campaign (enforced); utm_content distinguishes link variants, utm_term keywords, utm_id joins GA4 data imports; lowercase+hyphen is the reporting-safe convention (Campaign and campaign count separately). Pre-existing utm_* on the destination are stripped. The short link is self-hosted: slug = 7-char base62 derived deterministically from the FNV-1a hash of the full URL — same inputs always yield the same slug, no API or account; custom slugs are sanitized to [A-Za-z0-9_-]. QRs render via the qrcode package at L/M/Q/H error correction; the short QR points at a 302 that keeps every UTM dimension because they are baked into the destination. ## Inputs - **Destination URL** (text): example.com/pricing - **UTM source (utm_source)** (text): newsletter, twitter, podcast - **UTM medium (utm_medium)** (text): email, social, cpc - **UTM campaign (utm_campaign)** (text): spring-launch-2026 - **UTM content (utm_content, optional)** (text): hero-cta vs footer-link - **UTM term (utm_term, optional)** (text): project+management+tool - **Campaign ID (utm_id, GA4, optional)** (text): 1001 - **Force lowercase UTM values** (checkbox) - **Short-link domain** (text): go.yourdomain.com - **Custom slug (empty = auto)** (text): spring26 (leave empty for auto base62) - **QR error correction** (select) - **QR size (px)** (number) ## When to use - When a newsletter, social, or paid campaign needs a single GA4-valid link that reports source, medium, and campaign cleanly. - When you want a reproducible short URL on your own domain without a third-party shortener account or API. - When print or offline assets need a QR that still carries every UTM dimension after a 302 redirect. ## How it works - Enter the destination URL and the required utm_source, utm_medium, and utm_campaign values. Optional utm_content, utm_term, and utm_id can be added; any pre-existing utm_* parameters on the destination are stripped. - Optionally force lowercase UTM values (the reporting-safe convention), set your short-link domain, and leave the slug empty for a deterministic 7-character base62 slug derived from the FNV-1a hash of the full URL, or supply a custom slug that is sanitized to letters, numbers, underscore, and hyphen. - Choose QR error-correction level (L, M, Q, or H) and size in pixels. The result includes the full tracked URL, the short link, a QR pair (short and long), nginx/Vercel/Netlify redirect snippets, and a CSV tracking row. ## Use cases - Newsletter and email CTAs that need a short tracked link plus a QR for a printed insert. - Social or paid ads that require consistent lowercase UTM naming and a branded short domain. - Webinar or event links that join GA4 data imports via utm_id and need high-ECC QRs for print. ## Frequently asked questions ### Which UTM parameters are required? GA4 requires utm_source, utm_medium, and utm_campaign. utm_content, utm_term, and utm_id are optional. ### How is the short slug created? An empty custom slug produces a 7-character base62 slug from the FNV-1a hash of the full tracked URL, so the same inputs always yield the same slug. Custom slugs are sanitized to [A-Za-z0-9_-]. ### Does the short QR keep the UTM parameters? Yes. The short QR points at a 302 redirect whose destination already contains every UTM dimension. ### What happens to UTM parameters already on the destination URL? They are stripped so only the values you enter remain on the tracked URL. ### Can I host the short links on my own domain? Yes. The short link is self-hosted. The output includes redirect snippets for nginx, Vercel, and Netlify so you can map the slug on your domain. ## Related tools - [Fitness Workout PDF Generator](https://elysiatools.com/en/tools/fitness-workout-pdf-generator): Generate a printable workout-plan PDF from JSON or CSV data with exercise tables, progress boxes, and optional QR video links - [Time Series Anomaly Detector](https://elysiatools.com/en/tools/time-series-anomaly-detector): Upload CSV or JSON time series data, detect anomalies with Z-Score and IQR methods, and return a chart-backed report - [Train/Test Split with Stratification](https://elysiatools.com/en/tools/train-test-split-with-stratification): Class-stratified train/validation/test split or stratified k-fold for CSV/JSON datasets — seeded, reproducible, with distribution reports, leakage checks, SMOTE preview and CSV export. - [CSV to Database Migration Planner](https://elysiatools.com/en/tools/csv-to-database-migration-planner): Infer a relational schema from CSV data and generate create-table plus ALTER migration plans for PostgreSQL, MySQL, SQLite, or SQL Server - [JSONata Query & Transform Studio](https://elysiatools.com/en/tools/jsonata-query-transform-studio): Preview JSONata-style queries and transformations, compare results across sample payloads, and export the transformed output as JSON, CSV, YAML, or Markdown - [Time Series Forecast & Seasonality Analyzer](https://elysiatools.com/en/tools/time-series-forecast-seasonality-analyzer): Forecast future periods from CSV or JSON time-series data and inspect trend, seasonal, and residual decomposition in one report - [BOM Character Remover](https://elysiatools.com/en/tools/data-bom-remover): Remove BOM (Byte Order Mark) characters from text and file content.
