Make QR codes in bulk

No. The file is read in your browser and the codes are made on your device. Nothing in your list is sent anywhere, so it's safe for customer or stock lists.

Up to 5,000 rows a batch. Large batches take a little while on a phone, with a progress bar and a Cancel button. Split longer lists into several files.

One row per code, with the content (a link or any text) in one column. Add a column like "name" to name each file, such as table-1.png. A first row of headings is fine; tick "First row is headings". Download the sample CSV to see one.

Yes, an .xlsx file. The first sheet is used. Older .xls files need saving as .xlsx or CSV first.

Each code is drawn in your chosen colours and read back with a QR reader before it goes in the zip. If any don't read back exactly, you see their row numbers so you can fix them before printing.

PNG works everywhere, and the print sizes save at 300 ppi. SVG stays sharp at any size in design and print software. The PDF puts the codes on A4 or Letter paper, black on white, with the name under each and cut lines between.

No. Each code holds its link or text itself, so it keeps working with no account. A link code keeps working as long as the page it points to stays online.
