How to use MarkingBear

Single QR Studio

  1. Pick QR Code or a barcode format in the Studio tab.
  2. Type your value — or switch to URL, WiFi, vCard or SKU presets.
  3. Style dots, corners and colours, then add a logo if you want one.
  4. Open Frame settings to wrap the code in a banner, card or business shape.
  5. Download as PNG, SVG or a single-code PDF sized to your artwork.

Bulk Batch Generator

  1. Open the Bulk tab and drop a CSV file or paste one entry per line.
  2. MarkingBear keeps the first 100 rows per batch for browser safety.
  3. Watch the progress bar as previews render in async chunks.
  4. Choose a sticker sheet preset (A4 3×8, A4 2×5 or thermal 4×6).
  5. Export everything as a ZIP of images or a print-ready PDF sheet.

Supported barcode formats

Every format below is generated locally as vector output, so labels stay sharp from a 25 mm sticker to an A4 sheet.
