What is it for?

Running a marketing campaign with 30 different posters, prepping QR menus for 12 tables, equipping 50 product sheets with a manual link? Doing one QR code at a time — copy, paste, download, rename — eats half a day. This tool does it in seconds: paste your links, click, download a clean ZIP with the whole batch.

How to use it

1. Fill the list: type your URLs in the grid, or paste a column from Excel — the tool detects line breaks and creates rows automatically.
2. Add an optional caption: a short label (e.g. "PROMO", "TABLE 5") shown under the QR to identify the print at a glance.
3. Pick a design: a global theme, a module style (squares or dots), a font, and — if you want — a center logo cleanly placed in the middle.
4. Check the preview: on the right, the focused row's QR updates live. You can also download that single QR.
5. Generate the ZIP: one click, you get an outilo_qrcodes.zip with one PNG per link, named after your captions.

Tip: your rows and settings are saved locally (in your browser). Close the tab, come back later, nothing is lost. Ctrl+Z to undo, Ctrl+Y to redo.

Typical use cases

Best practices for first-scan reliability

• Keep URLs short: the longer the URL, the denser the QR and the harder to read from a distance. A short URL (Bitly, your own redirector) helps — the density indicator warns you above 120 characters.
• Strong contrast: dark modules on light background. Avoid light-on-light combos even if they look great on screen.
• Minimum print size: 2 cm side for a 30 cm scan distance (business card, menu), 5–10 cm for an A4/A3 poster, 40 cm minimum for outdoor display.
• White margin (quiet zone): leave at least 4 modules of margin so cameras detect the corners. Plain, Outilo and Custom themes include it by default.
• Center logo: OK up to ~25 % of the surface. The tool auto-bumps error correction to level H when a logo is set, but always test-scan before printing.

Expected CSV format

You can import a .csv file or paste directly from a spreadsheet. The tool reads two columns:

https://outilo.fr/outils,HOME
https://outilo.fr/categorie/marketing,MARKETING
https://outilo.fr/contact,CONTACT

Column 1 = the URL, column 2 = the optional text caption. No header needed, every line is processed directly.

Privacy & technical limits

Everything is computed in your browser through a Web Worker that keeps the UI smooth even for large batches. URLs never leave your device. Generated PNGs are 500×500 px (square or dot modules), good enough for print up to A4. Beyond 200 QR codes, expect a few seconds of computation; your browser stays usable during that time.
