PDF Merge and Split
This tool lets you merge multiple PDF files into one, or split a PDF into separate files. Merge is useful for combining reports, contracts, or scanned documents. Split lets you extract specific page ranges from a large PDF.
How to Merge PDFs
Select two or more PDF files. They will be merged in the order selected. Click Merge PDFs to produce a single combined file.
How to Split a PDF
Select a PDF file. Optionally specify page ranges (e.g. 1-3, 5, 7-10). Leave page ranges empty to split into individual pages. Click Split PDF to generate separate files.
▶Is there a file size limit?
The tool processes files in your browser. Very large PDFs (over 50MB) may cause performance issues. For best results, keep individual files under 20MB.
▶Does the tool preserve PDF formatting?
Yes, the tool preserves text, images, links, and formatting during merge and split operations. Form fields and annotations may not be fully preserved.
▶Is my data secure?
All processing happens in your browser. Your PDF files are never uploaded to any server. The tool uses the pdf-lib library for client-side manipulation.
