How to Generate Multiple QR Codes at Once (Bulk)

Needing 40 unique QR codes for 40 different inventory items, or one per table at an event, is a different problem than needing just one. A single QR code generator handles one code beautifully, but without a plan for tracking which code is which, a batch of dozens turns into a pile of identical-looking black-and-white squares nobody can tell apart after the fact.

The Real Problem Isn't Generating Codes, It's Tracking Them

Generating one QR code takes seconds. The actual bottleneck when you need many is keeping track of which code corresponds to which item, table, or asset once they're all downloaded and sitting in a folder named things like qrcode(1).png through qrcode(47).png. Solving that tracking problem first makes generating the batch itself almost trivial, in whatever order you get to it.

Set Up a Tracking Sheet Before You Generate Anything

Before opening a QR code builder, list every item that needs a code in a simple spreadsheet: one row per item, with columns for the item name or ID, the exact content the code should encode (a URL, an asset ID, a table number), and a final filename you'll save that code under. This ten-minute setup step is what prevents the classic bulk-QR mistake, ending up with 47 correct codes and no reliable way to match them back to their items.

Generating the Batch, One Code at a Time, With a Naming Convention

1. Open your tracking sheet and the generator side by side: Go to ezyimg.com/qr-generator in one window, your spreadsheet in another.
2. Copy the exact content for row one:Paste it into the generator's content field and confirm the preview looks right.
3. Download using your planned filename, not the default: Rename each download immediately to match the ID from your sheet, asset-104.png, table-12.png, rather than trusting a generic auto-generated filename.
4. Mark that row done in your sheet, then move to the next: Repeating this rhythm keeps you from losing your place partway through a long batch.
5. Spot-check a handful before printing the full set: Scan two or three finished codes at random and confirm they match their intended item before committing to a full print run.

Designing Content That Scales to Many Codes

A batch of QR codes is far easier to manage when the content each one encodes follows a predictable pattern instead of a one-off custom string per item. Encoding a URL like yoursite.com/asset/104 instead of a raw ID number, for example, means every code points somewhere useful even to someone without your tracking sheet, and lets you build codes ahead of time for IDs that don't exist yet, since the pattern extends cleanly to whatever number comes next.

Why a Consistent Style Matters Across a Batch

If your codes are going somewhere visible together, a shelf of inventory tags or a stack of table cards, keep size, colors and error correction level identical across every code in the batch rather than adjusting settings item by item. A batch that looks visually consistent reads as more professional and organized, and it removes one more variable to think about while you're focused on getting the content of each code exactly right.
