รวม PDF
What this tool does
Join several PDF files into one document in the order you select. Ideal for combining chapters, invoices, or scanned pages.
Supported formats
Input: multiple PDF files. Output: a single merged PDF.
How to use
Upload two or more PDFs (order matters — files are merged in the order listed), click Convert, and download the combined PDF.
Limitations & tips
Encrypted PDFs must be unlocked before merging. If one file is damaged, the whole job may fail. Very large total size (hundreds of MB) can exhaust browser memory; merge in smaller batches if needed.
