Bulk Page Number Image Generator｜Create Transparent PNGs for Comics & Artbooks
This tool automatically generates a complete set of transparent PNG images for page numbers (known as "nombre" in manga production). It's designed for comic artists, illustrators, and self-publishers to eliminate the tedious task of manually creating and placing each page number asset.
💡 Tool Overview
- Batch Generation: Instantly create all page number images for your entire book, from the start page to the end, in a single operation.
- Customizable Canvas: Choose from standard print-ready presets (A5, B5, A4 at 350dpi) or enter your own custom canvas dimensions in pixels.
- Manga & Artbook Ready: Supports both "Right-to-Left" (for manga) and "Left-to-Right" (for artbooks/magazines) binding directions, automatically adjusting placement for outer/inner edges.
- Flexible Design Controls: Customize the appearance by changing the font (serif, sans-serif), size, color, and decorative formatting (e.g.,
- 1 -,[ 1 ],001). - Transparent Background: All images are exported as high-quality PNGs with a transparent background, making them easy to import and place onto your pages in any illustration software like Clip Studio Paint or Photoshop.
🧐 Frequently Asked Questions
Q. What do the "Binding Direction" and "Horizontal Position" options do?
A. Binding Direction tells the tool how your book will be bound. "Right-to-Left" is standard for Japanese manga, while "Left-to-Right" is used for most Western books and artbooks. This setting is crucial for the Horizontal Position options like "Outer Edge" and "Inner (Hidden)". The tool uses the binding direction to automatically determine which side is the outer edge (fore-edge) and inner edge (gutter) for even and odd pages, ensuring the numbers are always placed correctly.
Q. Are my settings or generated images uploaded to a server?
A. No. This tool operates entirely within your web browser. All image generation is handled on your computer, and no data is ever sent to a server. Your project settings and files remain private.
Q. The browser is asking for permission to "download multiple files". Is this safe?
A. Yes, this is a standard security feature. Because the tool generates a separate image file for each page number in the range you specify, your browser asks for your permission before allowing a website to download many files at once. You must click "Allow" for the batch generation process to complete successfully.
📚 Did You Know? About "Nombre" in Manga Production
The term "nombre" (ノンブル), borrowed from the French word for "number," is widely used in the Japanese manga and doujinshi (self-publishing) community to refer to page numbers. Proper nombre placement is a critical step in preparing files for printing.
A common professional technique is to use "hidden nombre" (隠しノンブル, kakushi-nombre). These are page numbers placed in the inner margin of the page—the "gutter" or "ノド" (nodo)—where they will be hidden from view after the book is bound. This keeps the artwork on the page clean and free of visible numbers while still providing an essential guide for the printing company to assemble the pages in the correct order. This tool's "Inner (Hidden)" position setting is specifically designed for creating these hidden nombre assets. As a guideline for print, they are typically placed 3-5mm from the binding edge (which corresponds to about 40-70 pixels in a 350dpi file).
