PDF Merge & Split
Merge PDFs together, or pull out just the pages you need. All processing happens in your browser — files are never uploaded.

Private by design. This page has no backend. Your files are processed by JavaScript running on your own device and are never sent anywhere.
How PDF Merge & Split works
Merge mode
Combine the pages from two or more PDF files into a single document. All pages from each input file are included in the order you add them. The output preserves the page layout, fonts, and images from each source PDF.
Split mode
Extract selected pages from a single PDF into a new file. Specify which pages you want to keep and a new PDF containing only those pages is created, along with all the fonts, images, and other resources those pages depend on.
Page range syntax
Use commas to separate individual pages and dashes for ranges. Examples:
1,3,5— pages 1, 3, and 51-5— pages 1 through 51-3,5,7-10— pages 1–3, 5, and 7–10last— the final page1,3,last— pages 1, 3, and the last page
Limitations
Merge works by renumbering objects across input files; it works well for PDFs produced by common tools such as Chrome, Firefox, LibreOffice, and standard PDF libraries. PDFs that use compressed cross-reference streams (PDF 1.5+) are supported via decompression.
Split correctly copies pages and all their dependent resources (fonts, images, color spaces) but may not handle every edge case with complex features like embedded JavaScript, annotations, or linearization dictionaries.
Password-protected or encrypted PDFs cannot be processed. All processing happens in the browser; files are never sent to a server.
