🧾 How to Use the PDF Splitter Tool

The PDF Splitter Tool is a simple, powerful, and free tool that lets you split large PDF files into smaller ones without installing any software. It works directly in your browser — no backend or server needed. Here’s a complete step-by-step guide on how to use it effectively.

---

🌟 Step 1: Open the PDF Splitter Tool

To begin, open the PDF Splitter Tool in your web browser. You can host this tool on your own website or use it locally if you downloaded the HTML file. The interface is clean and easy to navigate, with a file upload area at the top, page previews in the middle, and action buttons at the bottom.

---

📤 Step 2: Upload Your PDF File

Click on the “Drop PDF file here or click to upload” area. A file picker dialog will open. Select the PDF file you want to split from your computer. Once uploaded, the tool will automatically render and preview all the pages of your PDF in a grid layout.

Each page will be displayed as a small thumbnail preview with its page number shown on the corner. This helps you visually identify the content on each page.

✅ Step 3: Select Pages to Split

There are two ways to select the pages you want to split from your PDF:

Option A: Click to Select Pages

Click directly on the page thumbnails. When you click a page, it gets highlighted with a border, meaning it’s selected. You can click again to deselect a page. All selected pages will be part of the new split PDF.

Option B: Enter Page Range

If you prefer typing, use the input box labeled “Or enter pages to split (e.g., 1-3,5)”. You can enter specific page numbers or ranges, like:

CopyEdit1-4,6,8

This means pages 1 to 4, page 6, and page 8 will be included in the split.

Note: If you use both methods, the tool will prioritize the range input box.

🔢 Step 4: See Selected Page Count

Just below the input field, the tool displays the number of pages you’ve selected. This helps you double-check your selection before proceeding.

✂️ Step 5: Click “Split PDF”

Once your desired pages are selected, click the “Split PDF” button. The tool will process your selection using PDF-lib (a JavaScript library) and create a new PDF file that contains only the selected pages.

You don’t need to upload your file to any server — all processing happens inside your browser using client-side JavaScript.

---

👀 Step 6: Preview the Split PDF

After splitting, the tool will show a live preview of the new split PDF right inside the page. This allows you to check if everything looks correct before downloading.

The preview appears below the main area in a built-in PDF viewer, so you don’t have to open a separate tab or application.

---

📥 Step 7: Download Your Split PDF

If everything looks good in the preview, click the “Download Split PDF” button. The tool will instantly generate a download of your new split file. It’ll be saved to your device with a name like split-pdf-168298121.pdf.
