Design peptide vial labels and print them to a NIIMBOT thermal printer straight from your browser — or download a print-resolution PNG.
Everything renders at 203 dpi (8 px/mm) and prints over Web Bluetooth. No installs, no accounts. Works in Chrome and Edge on desktop and Android.
This label maker connects to NIIMBOT thermal printers using the same open Web Bluetooth protocol as niim.blue, so you can go from an empty template to a printed vial wrap without opening a separate app. It works with NIIMBOT D11, D110, D101, B1, B21, B203, B18 and other models supported by Web Bluetooth. Filter label sizes by printer family — narrow D-series tapes (40×12, 30×12, 30×14, 30×15, 74×12.5 mm) or wider B-series die-cut labels (30×20, 40×20, 40×30, 50×30, 60×40, 50×14 mm) — or type a custom size, then lay out the fields researchers typically track: compound name, strength, bacteriostatic-water volume, reconstitution and use-by dates, batch or source, and a free-text note. A community template gallery below the designer offers ready-made starting points shared by other users, each with a live preview.
Because thermal printing is one-bit (pure black on white), the preview shows the exact thresholded bitmap that will be sent to the printer. A threshold slider and printer-density control let you dial in crisp text and clean edges. Add a QR code linking to a compound reference, drop in a monochrome glyph such as a syringe or a “keep cold” snowflake, and pick a border and font that stay legible at small sizes.
Web Bluetooth is available in Chrome and Edge on desktop and Android. iOS and iPadOS browsers, plus Safari and Firefox, cannot connect to Bluetooth devices from a web page — on those platforms the Download PNG fallback produces the same print-resolution image to run through the official NIIMBOT app.
Works with NIIMBOT D11, D110, D101, B1, B21, B203, B18 and other models supported by Web Bluetooth. Narrow D-series tape printers (plus the B18) handle 12–15 mm tapes, while wider B-series printers take die-cut labels up to 50×30 or 60×40 mm. When you connect, the printer reports its model, the correct print routine is selected automatically, and the designer warns if the chosen label size is wider than that printer's print head.
A gallery of label designs shared by other users, shown with live previews rendered from the exact template data. Applying one copies the layout — size, font, border, QR, and clipart settings — while any content you already typed stays untouched. You can share your own design from the same panel; submissions are public and pass through a content filter.
Web Bluetooth is required, which means Chrome or Edge on desktop (Windows, macOS, Linux, ChromeOS) or Android. Safari, Firefox, and every browser on iOS and iPadOS cannot use Web Bluetooth — on those, use the Download PNG button and print the image through the official NIIMBOT app.
Thermal printers are one-bit devices: every pixel is either black or white. Use the 1-bit threshold slider so text renders as solid black on a clean white background, and raise the printer density if fine details drop out. The on-screen preview shows the exact thresholded bitmap that will be sent to the printer.
Common fields include the compound name, the amount in the vial (mg), the volume of bacteriostatic water used to reconstitute, the reconstitution date, a use-by/BUD date, a batch or source reference, and a QR code linking to reference information. This tool surfaces those fields; it does not provide dosing instructions or medical advice.
When you pick a peptide from the catalog, the QR encodes its peptiq.io reference page. With no catalog peptide selected, the QR instead encodes a compact text summary of whatever label fields you filled in, so the code stays useful offline.
Yes. The page reads URL parameters — name, peptide, mg, ml, recon, bud, batch, and note — so a calculator, protocol screen, or the PeptIQ mobile app can deep-link straight into a ready-to-print label.
Educational tool only, not medical advice. Labeling fields are provided for organization and record-keeping; this tool does not recommend doses or handling practices. Follow product labeling and applicable compounding standards.
