Bulk QR Code Generator

How the bulk QR code generator works

Making QR codes one by one is fine for a single poster. For product labels, event tickets, table menus, asset tags or a mail merge, you need a bulk QR code generator. Paste a list and this tool encodes every line as its own QR code, names each file sensibly and packs them into a single ZIP download.

The codes are generated on our server by a QR encoder that follows the ISO/IEC 18004 standard: versions 1 to 40, all four error correction levels and automatic mask selection. Every code has been tested to scan with standard readers. Nothing depends on a third-party API, so your URLs are not sent anywhere else, and the codes are static: they never expire and keep working with no subscription.

Batch QR codes from Excel

The From CSV / Excel tab is for full control. Each row is filename, content, caption, for example table-01, https://example.com/menu?t=1, Table 1. In Excel or Google Sheets, put those three columns side by side, save or copy as CSV, and paste. The file name becomes the image name in the ZIP, and the caption can be printed under the code. A header row is detected and skipped automatically.

QR codes with text, logos and colours

• QR code with text: choose Text under the code to print the URL, the encoded text or your own caption below each code, in both PNG and SVG.
• Logo: upload a PNG, JPG, GIF or WebP logo and it is placed in the centre on a clean pad. Error correction is raised to H automatically, which lets the code survive the covered area.
• Colours: any foreground and background colour. The tool warns you when contrast is too low or the code is inverted (light on dark), since many phone scanners cannot read those.
• Size and quiet zone: from 128 to 2,048 pixels, with an adjustable white border. Keep at least 2 modules of quiet zone, 4 is the standard.
• PNG or SVG: PNG for screens, documents and labels. SVG is vector, so it stays sharp at any print size, from business cards to banners.

Wi-Fi, vCard, email, SMS and map QR codes

Besides URLs and plain text, the generator builds the special formats phones recognise:

• Wi-Fi QR code generator: enter the network name, password and security type. Guests scan and join without typing the password. Hidden networks are supported.
• vCard: name, company, job title, phone, email, website and address. Scanning offers to save the contact, ideal for business cards and name badges.
• Email: opens a new email with the address, subject and body filled in.
• SMS and phone: start a text message or a call to your number.
• Map location: latitude and longitude that open in the phone's maps app.

Before you print a batch

• Test first: scan a few codes with two different phones before printing hundreds.
• Size: print codes at least 2 cm (0.8 in) wide for close scanning. As a rule, the scanning distance is about ten times the code width.
• Keep URLs short: shorter content means fewer modules and an easier scan. Add tracking with the UTM builder but keep parameter names short.
• Use the print sheet: download the printable HTML sheet for a quick grid of all codes with their captions, then print or save as PDF.
• Use SVG for professional print so the printer can scale without blurring.

Need many URLs to encode? Generate clean page addresses with the URL slug generator, or unique ticket IDs with the UUID generator.
