Batch QR codes & printable cards
Make product links useful on paper: enter one record or import a CSV, choose shelf, table or parcel aftercare cards, review the preview and export images or a full PDF.
Review & export
Enter content or import a CSV, then generate.
Edit imported records
Correct a row here, then generate again. Duplicate content is skipped.
Print the PDF at actual size / 100%, without “fit to page”. Test-scan one print first. Card borders are cutting guides; table cards are flat inserts for a stand.
Frequently asked
Can I change a static code later?
No. Codes encode the input directly, without a redirect through this site. There is no scan tracking, hosting or account. Changed content needs a newly printed code.
What CSV columns do I need?
Use a header row followed by one record per row. Map title, content and note before importing; title and note are optional, content is required. Quoted commas, line breaks and escaped double quotes are supported. The limit is 500 records and 2 MB.
How do you keep printed codes readable?
Every code retains a four-module white quiet zone. Output must be at least 20mm wide and 0.4mm per module. If paper, cards per page or margins make a code too small, that record fails with guidance to reduce cards per page. Test a print at actual size before use.
Do you store Wi-Fi passwords or product links?
No. Entries stay in this page’s memory. They are not uploaded, stored in browser storage or placed in the page URL. Refreshing clears them. Exported materials contain the encoded information; keep Wi-Fi materials secure.
What do the exports include?
Every material includes its title, QR code and note. PNG exports at 300 DPI; SVG keeps QR modules as vectors; ZIP contains PNG and SVG for every successful record. PDF follows your A4 or Letter paper, cards per page and margins. Text that will not fit is flagged instead of clipped.
