About Merge PDF
Need to merge PDF files quickly? TheToolss lets you combine PDFs online for free. Add two or more documents, drag to reorder, optionally pick page ranges, then download one merged PDF. Page ranges let you pull only part of a source file, so you can assemble a submission packet from several documents without splitting them first. Because the work happens on your device rather than a server, very large merges depend on your available memory — a phone will handle fewer pages at once than a laptop. No account and no server upload required.
How to use Merge PDF
- Open Merge PDF and select two or more PDF files from your device.
- Reorder the files and optionally enter page ranges (for example 1-3,5).
- Click Merge PDF, then download the combined file.
