How do I reorder PDFs before merging?

In Merge mode, each uploaded PDF appears as a draggable card with a grip handle. Click and drag any card to move it up or down. The position determines page order in the merged document - pages from the first PDF appear first, followed by the next PDF's pages.

How does the page range input work for splitting?

Enter page ranges using comma-separated values. Single pages (e.g. "5"), ranges (e.g. "1-5"), or combinations (e.g. "1-3, 5, 7-9") are all supported. Duplicates are removed and pages are extracted in ascending order.

Understanding the PDF Page Merger / Splitter

What is a PDF Page Merger / Splitter?

A PDF page merger lets you combine multiple PDF files into a single unified document, while a PDF splitter lets you extract specific pages from a PDF into a new file. Our tool combines both functions in one interface - upload your PDFs, choose merge or split mode, and the tool handles the rest using pdf-lib, all running locally in your browser.

How Our PDF Merger Works

Switch to Merge mode and upload two or more PDF files. Each file appears in a list showing its name, size, and page count. Drag files to reorder them - the position in the list determines the page order in the merged document. Click "Merge PDFs" to combine them into a single file that downloads automatically. All page content, formatting, and embedded elements are preserved through pdf-lib's copy operation.

How Our PDF Splitter Works

Switch to Split mode and upload a single PDF file. The tool reads the PDF and displays its page count. Enter a page range using simple comma-separated notation like "1-3, 5, 7-9" to specify which pages to extract. The tool parses the range, validates all page numbers against the document's total pages, deduplicates any overlaps, and extracts the pages in ascending order into a new PDF file that downloads automatically.

Privacy, Security & Availability

Your documents are important. Our PDF page merger/splitter uses pdf-lib to process everything locally in your browser - your PDF files are never uploaded, stored on any server, or transmitted over the network. There are no file size limits, no signup required, and the tool is completely free to use forever. Since everything runs client-side, it works even without an internet connection after the initial page load.

Frequently Asked Questions About PDF Page Merger / Splitter

What is a PDF Page Merger / Splitter?

A PDF page merger combines multiple PDF files into a single document, while a PDF splitter extracts specific pages from a PDF into a new file. Our tool does both - upload PDFs, choose merge or split mode, and download the result. All processing uses pdf-lib in your browser.

How do I reorder PDF pages before merging?

In Merge mode, each uploaded PDF appears as a draggable card with a grip handle on the left side. Click and drag any card by its grip handle to move it up or down in the list. The position in the list determines the page order in the merged document - pages from the first PDF appear first, followed by pages from the second, and so on.

How do I use the split page range feature?

Enter a page range in the text field using comma-separated values. You can use single pages (e.g. "5" extracts page 5), ranges (e.g. "1-5" extracts pages 1 through 5), or combinations (e.g. "1-3, 5, 7-9" extracts pages 1, 2, 3, 5, 7, 8, 9). Duplicate page numbers are automatically removed, and pages are extracted in ascending order.

Is my data safe when using this PDF tool?

Absolutely. Our PDF merger/splitter uses pdf-lib entirely in your browser. Your PDF files are never uploaded to any server, stored in any cloud, or transmitted over the network. All processing stays on your device - your documents never leave your computer.

What version of PDF is supported?

pdf-lib supports PDF 1.7 format, which covers the vast majority of PDF files in use today. Most modern PDFs created by Adobe Acrobat, web browsers, Google Docs, Microsoft Office, and other tools are fully compatible. Encrypted or password-protected PDFs are not supported.

Are there any file size limits?

There are no hard limits imposed by the tool. The practical limit depends on your device's available RAM, since all PDF processing happens in the browser. For very large PDFs (hundreds of megabytes), ensure your browser has enough memory available. Most modern devices can handle PDFs up to several hundred megabytes.

Does the merger preserve formatting, fonts, and images?

Yes. pdf-lib preserves all page content including text, fonts, images, vector graphics, annotations, and form fields when copying pages between PDFs. The merged output maintains the original formatting of each source document. However, interactive form fields and JavaScript actions may not transfer perfectly.

Is this tool free to use?

Yes, the PDF Page Merger / Splitter is completely free to use with no signup required. There are no hidden fees, no premium features, no file count limits, and no ads. Since everything runs locally in your browser using pdf-lib, there are no server costs.
