Free bulk QR code generator

A bulk QR generator creates a separate static code for each row in a CSV file. Choose your CSV above, inspect the first rows, and download a ZIP of PNG or SVG images. The entire batch stays in your browser, with progress updates, cancellation, and processing that yields between codes so the interface remains usable.

Prepare the data before creating the batch

Bulk generation is useful when each item needs its own destination: equipment labels, resource cards, branch information, or a set of product instruction links. It saves repetitive entry while keeping every code independent. There is no central collection of dynamic records behind the resulting images.

Treat the CSV as the source of truth for the batch. Keep a clear relationship between each row and the item that will receive its code. A perfectly scannable image attached to the wrong product is still an error, so planning the labeling and print workflow matters as much as generating the files.

Create a ZIP from your CSV

1. Download the example CSV or prepare a file with a header row. Use one record per code, with fields matching the relevant generator form.
2. Set type to values such as url, text, wifi, or vcard. For a link-only file, the type can remain url on every row, with the destination in the url column.
3. Choose the file in the bulk section. Read the validation result and inspect the first five records to catch an incorrect delimiter, shifted column, or wrong destination field.
4. Select PNG or SVG and start the ZIP export. The tool displays progress and offers cancellation while it generates one image at a time.
5. Extract the archive, match its numbered filenames to the source rows, and scan representative codes. For important or varied batches, verify every distinct destination before printing or attaching labels.

Commas, quotation marks, and line breaks inside a CSV value need standard CSV quoting. Enclose a field in double quotes and double any quotation marks inside it. A spreadsheet’s CSV export can help, but inspect the saved file’s column names and encoding before using it.

Choose a format for the next stage

PNG exports are 512 pixels square in the bulk workflow and are convenient for many document and label tools. SVG files suit layouts that require resizing while retaining vector edges. Your current design is applied across the batch; a locally selected logo is included when present.

Different payload lengths can create different pattern densities even when the styling is identical. A batch containing short URLs and long contact cards should be proofed at the densest end of the range. Avoid assuming that the first easy-to-scan row represents every code in the archive.

Keep large jobs manageable

The browser yields after individual codes so progress can paint and the cancel button can respond. ZIP packing is also asynchronous. A large batch can still take time and consume memory, especially with lengthy payloads or complex SVG artwork; responsiveness is not a promise of instant completion.

Keep the page open until the download finishes. If a device is short on memory, split a very large source file into deliberate batches while retaining a clear naming scheme. Cancellation does not upload or transfer unfinished records; it stops the local job and leaves your source file under your control.

Prevent printing and matching mistakes

Check a few extracted filenames against the first, middle, and last source rows before merging images into a layout. Repeated destinations remain separate numbered files rather than overwriting one another. If a downstream label application sorts names, the padded numeric prefixes help keep the intended order.

Print a sample sheet and confirm both scanning and attachment accuracy. Keep the original quiet zones, choose an appropriate physical size, and avoid a workflow that stretches each image to fill a non-square box. Finally, archive the CSV, ZIP, approved layout, and batch notes together. The codes are static, so correcting a wrong row means creating replacement images and replacing any affected printed labels.
