How to create your first barcode label with Label Studio
Create your first barcode label with sample data, understand record fields, preview the design and download a printable PDF in Label Studio.
Import Excel and CSV to create barcode labels
Map Excel or CSV columns to barcode values, names and quantities. Preserve leading zeros, choose a worksheet and append or replace your label data.
Generate sequential serial numbers with prefixes and leading zeros
Generate serial numbers such as WH-000001 with a prefix, suffix and fixed minimum digits, then turn the sequence into printable barcode labels.
Edit, filter and select barcode records without changing your source file
Edit label data, filter errors and duplicates, bulk-edit selected records and understand the difference between hiding codes and excluding exports.
Choose a barcode type: Code 128, EAN, UPC, QR and GS1-128
Compare the ten barcode formats in Label Studio, check input restrictions and choose the right symbology for your labels and scanner.
Create QR codes for URLs, Wi-Fi, email, phone and vCard contacts
Build static QR codes in Label Studio, import QR payloads in bulk and print URL, Wi-Fi, email, phone or contact labels with illustrated steps.
Design barcode labels with exact dimensions, text and a logo
Set label sizes in mm or inches, position text and barcode elements, add a logo and fix text overflow before exporting labels from Label Studio.
Display barcodes on screen: grid, full screen and anti-glare controls
Browse barcode labels, adjust screen scanning settings, use a label grid and export selected codes without changing your print template.
Print barcode labels on A4 or rolls and export PDF, PNG or SVG
Choose label export scope, paper size, copies and DPI. Calibrate A4 or thermal-roll printing and download PDF, PNG, SVG or ZIP label batches.
Scan barcodes and QR codes with a camera, image or USB scanner
Start a scan session, read barcode images, use a camera or keyboard scanner and choose unique-serial or repeated-count scanning in Label Studio.
Reconcile inventory scans: matched, duplicate, missing and surplus items
Interpret scan statuses, investigate duplicate or unknown codes and export complete scan logs and inventory differences from Label Studio.
Back up and restore Label Studio projects between devices
Save a Label Studio JSON backup, restore a separate project and move labels and scan history between browsers without losing your original data.
Use Label Studio on mobile and offline after the first load
Find mobile navigation, install the web app when supported, prepare offline resources and safely apply updates while keeping project backups.
