- How do I prepare my CSV file?
- Open your attendee list in Excel or Google Sheets. Make sure the first row contains column headers (e.g. "Name", "Company", "Title"). Go to File → Download → CSV. The tool accepts UTF-8 and most standard CSV encodings. If you see garbled characters, re-save your file as UTF-8 from Excel (File → Save As → CSV UTF-8).
- How many badges fit on one page?
- It depends on your paper and badge size. For US Letter with the Standard badge (3.5 × 2 in), you get a 2-column × 4-row grid = 8 badges per page. For A4 with Standard, the tool fits 2 × 5 = 10 badges per page. Large badges (4 × 3 in) on Letter yield 1 × 3 = 3 per page. The exact count and layout are shown in the preview before you download.
- Is my attendee data kept private?
- Yes — completely. The CSV is read directly by your browser using the File API. No data is sent to any server. The PDF is generated locally using the open-source pdf-lib library. You can disconnect from the internet after the page loads and the tool will still work.
- What print settings should I use?
- Open the downloaded PDF in any PDF viewer (Adobe Acrobat, Preview on Mac, Chrome's built-in viewer). Set paper size to match what you chose in the tool. Set scale to "Actual size" or 100% — never "Fit to page", which would shrink the badges. If cut guides are enabled, use scissors or a paper trimmer along the dashed lines. For best results, print on card stock (200–250 gsm).
- Can I add a logo or custom colors?
- This tool focuses on fast, friction-free text badges. For full graphic design (logos, custom backgrounds, photos), export your layout from this tool as a reference and recreate it in Canva or Adobe InDesign using the same badge dimensions. Alternatively, use a pre-printed badge template and feed it through your printer a second time with just the text layer from this PDF.
