How to generate barcodes & QR codes

Create retail and industrial barcodes across 8 symbologies — or styled QR codes — with live preview, batch labels and PNG/SVG export.

The Barcode & QR studio validates check digits, previews live, and exports print-ready files — so a code you generate here will actually scan at the register or on the shelf.

Choose a symbology and enter your value

Open Barcode from the sidebar. Pick a symbology — Code 128, GS1-128, EAN-13, UPC-A, EAN-8, Code 39, Code 93 or ITF — then type your value. A live, scannable preview renders on the right, with check-digit validation done for you. Tap Use sample to see a valid example.

Pick from 8 symbologies, type a value, and the scannable barcode renders live — export as PNG or SVG.

Style the appearance

Set bar width (S/M/L/XL), height, toggle the human-readable value text, and choose bar & background colors (or a custom pair). Switch orientation between horizontal and vertical to fit your label.

Bar width, height, colors and orientation — plus batch sequences with prefix, start number and step.

Generate a batch with labels

Need many codes at once? Use Batch & labels — a Sequence (prefix, start number, step, count) like INV-100-A, INV-101-A… or a Custom list. Set the column count for a printable sheet.

Download as PNG or SVG

Export a single code or the whole batch as PNG (for documents) or SVG (crisp at any size, ideal for print). You can also scan a barcode from an image to read its value back.

Use-case example

Labeling inventory for a small shop. Priya needs shelf labels for 12 new SKUs. She picks Code 128, opens Batch & labels → Sequence, sets prefix INV-, start 100, step 1, count 12, suffix -A, and 3 columns. She exports the sheet as SVG and prints crisp, scannable labels — INV-100-A through INV-111-A — in one go.

Pro tip

Use SVG for anything you'll print — it stays razor-sharp at any label size, unlike a scaled-up PNG.

Frequently asked questions

Which barcode symbologies are supported?

Eight: Code 128, GS1-128, EAN-13, UPC-A, EAN-8, Code 39, Code 93 and ITF — with automatic check-digit validation.

Can I generate many barcodes at once?

Yes. Batch mode creates a sequence (prefix, start, step, count) or a custom list, laid out in printable columns.

PNG or SVG — which should I use?

PNG for embedding in documents; SVG for printing, since it stays sharp at any size. Both are one-tap exports.

Is the barcode tool free?

It's part of iSmart Measure Pro, which includes a 7-day free trial. The core unit converter and calculator are free.
