Barcode Mint: A Free Barcode and QR Generator Built to Just Work
Generating a barcode sounds like a solved problem until you actually need one for a real product label, a GS1-compliant retail tag, or a print run of a thousand event tickets. Most free generators online hand you a single QR code with a watermark stamped across it, or a barcode that looks right on screen and then fails to scan the first time someone points a real scanner at it in a warehouse.
Barcode Mint exists to close that gap — a free, no-signup generator that actually produces codes reliable enough to print and ship.
What Barcode Mint does
Barcode Mint is a free online barcode and QR code generator that produces production-ready codes in seconds, with no signup and no watermark. It supports 100+ symbologies — QR, Data Matrix, PDF417, Aztec, Micro QR, Code 128, Code 39, EAN-13, UPC-A, MaxiCode, DotCode, and the full GS1 family (GS1 QR, GS1 Digital Link, GS1 Data Matrix) — with live customization of size, colors, margins, and error correction before you export.
Every code is encoded with a reference-grade engine (BWIPP), the same barcode-rendering library used across professional labeling software, so the output isn't a rough approximation — it's built to scan reliably the first time, whether that's a retail barcode at checkout or a GS1 code moving through a warehouse.
What's broken about the free-generator alternative
Most free barcode tools online optimize for the wrong thing. They're built to get you one code fast, which means a single QR generator with a watermark you have to pay to remove, or a one-off image with no batch option when you actually need five hundred labels for a print run.
The deeper problem is correctness. A barcode that renders as an image is not the same as a barcode that scans. Quiet-zone spacing, module sizing, and error-correction level all affect whether a real scanner reads the code correctly — details a simple image generator doesn't account for, and that only surface as a failure once the codes are already printed.
Barcode Mint is built around getting those details right by default. The BWIPP encoding engine handles the symbology-specific rules correctly, error correction is configurable rather than fixed, and nothing is watermarked or gated behind a signup just to get a clean export.
How it works
100+ symbologies, one tool — QR, Data Matrix, PDF417, Aztec, Code 128, EAN-13, UPC-A, and the full GS1 family, so the right format for the job is always available rather than needing a different tool per barcode type.
Live customization — Adjust bar width, height, colors, margins, and error correction level (L/M/Q/H) with a real-time preview, so what you see before exporting is what actually gets printed.
Bulk generation from CSV — Generate an entire batch of codes at once for product labels, inventory tags, or a full print run, instead of exporting one at a time.
PNG and SVG export, no watermark — Clean exports for screen or print, free, with no account required.
Developer API — One REST API request returns a PNG or SVG, so barcode and QR generation can be built directly into another app or workflow, with commercial licensing included and volume tiers as usage scales.
Why different formats matter
Not every barcode job wants a QR code. QR reads natively on virtually any smartphone camera, which makes it the right default for menus, packaging, and marketing. Data Matrix packs the same data into a much smaller physical footprint, which is why it shows up on small industrial parts. Aztec drops the quiet-zone requirement entirely, useful for dense mobile tickets where every millimeter matters. PDF417 stores far more data per code than a typical barcode, which is why it's the format behind airline boarding passes and ID cards. Barcode Mint supports all of them, so the choice is about the job, not about which tool happens to be open.
Who this is for
Online sellers and warehouse teams generating product labels and inventory tags at volume. Restaurants building QR menus. Event organizers producing tickets. Marketers running a campaign that needs a WiFi-sharing card or a promotional QR code. Developers who want barcode generation built into their own product via API instead of a manual export step.
Pricing
Free in the browser, with unlimited PNG and SVG exports and no watermark. Pro ($12/month or $120/year) adds bulk CSV batch generation, vector (PDF/EPS) export, and commercial licensing for teams. The REST API is tiered separately, from 500 requests a month up to 50,000, with custom Enterprise pricing above that.
