Invoice Generator

NinjaFunction's Invoice Generator builds a professional PDF invoice in your browser. Add your logo, sender and customer details, an invoice number and dates, then list your items with a quantity and price. Choose a currency, add a discount, tax, shipping or an amount already paid, and the subtotal, total and balance due are calculated for you. Pick A4 or US Letter and an accent colour. Your invoice never leaves your device.

Receipt Generator

NinjaFunction's Receipt Generator creates a printable receipt as a PDF sized for 80 mm or 58 mm thermal rolls. Enter your shop details, add items with quantity and price, apply a discount and tax, and enter the amount paid to show the change. The page height fits the receipt exactly. Everything is made in your browser and nothing is uploaded.

Certificate Maker

NinjaFunction's Certificate Maker builds a landscape certificate of achievement, completion or appreciation as a PDF. Write the title, the recipient and a short reason, add the date and up to two signature lines, add your logo, and pick the Classic, Modern or Elegant style and your own colour. Choose A4 or US Letter. Long names shrink to fit. Everything is made in your browser and nothing is uploaded.

Barcode Label Sheet

NinjaFunction's Barcode Label Sheet turns a list of values into a printable PDF of barcode labels. Choose Code 128, Code 39, EAN-13, EAN-8, UPC-A, ITF or Codabar, pick an Avery or A4 label sheet or enter a custom layout, set the number of copies and skip labels that are already used. Each line is checked, and invalid values are listed. The barcodes are drawn as sharp vector shapes, and your list never leaves your browser.

Printable Calendar

NinjaFunction's Printable Calendar creates a landscape PDF calendar for any month or year from 1900 to 2200. Print one large month, twelve large months with a page for each, or the whole year on one page. Start the week on Sunday, Monday or Saturday, choose from seven languages, add your own title, colour, brand logo and background image, and pick A4 or US Letter. Leap years are handled correctly. Nothing is uploaded.

Name Badge & ID Card Maker

NinjaFunction's Name Badge & ID Card Maker turns a list of names into printable cards as a PDF. Type one person per line with an optional role and ID, add your organization, event title and logo, choose a header band or side stripe style, pick a card size such as an ID card, name tag or event badge, and show each ID as a barcode or QR code. Cards fill A4 or US Letter pages with cutting outlines. Your list never leaves your browser.

Shipping Label Maker

NinjaFunction's Shipping Label Maker creates printable shipping labels as a PDF. Add your sender details and logo, then one or many recipients, each with an address, phone, order number, tracking number and weight. Paste a list to make a whole batch at once. Labels include a Code 128 barcode and FRAGILE, THIS SIDE UP or KEEP DRY marks, in 4 x 6 inch, A6, A5, or four to a page on A4 and Letter. Your addresses never leave your browser.

Printing tools help you design and test labels for thermal printers. They are especially useful in warehouses, shipping, retail and manufacturing, where labels with barcodes, addresses and product details are printed every day.

The ZPL Editor lets you write ZPL (Zebra Programming Language) code and see a live preview of the label as you type. You can check the layout, text and barcodes before printing, which saves label stock and avoids sending broken jobs to the printer. When the label looks right, download it and use it with your Zebra or ZPL-compatible printer.

Frequently Asked Questions

What is ZPL?

ZPL (Zebra Programming Language) is a text-based language used to design labels for Zebra and many other thermal printers. Commands describe where to place text, barcodes, lines and images on the label.

Why should I preview a ZPL label before printing?

A preview shows you exactly how the label will look, so you can fix positions, font sizes and barcode data before printing. This saves label stock and avoids wasted print runs.

Do I need a Zebra printer to use the ZPL Editor?

No. You can write and preview ZPL code without any printer connected. You only need a printer when you are ready to print the finished label.
