PRACTICAL GUIDE
How to use Merge PDF
Last reviewed
Merge two or more PDF files into one document in the order you select them. FroggoTools reads and combines the documents in browser memory, so contracts, invoices and other PDFs do not need to be uploaded to a conversion service.
How to use it
- Select two or more PDF files in the required order
- Review each source name, page count and the final page map
- Merge the documents in the browser
- Download the combined PDF and open it once to verify the page order
Combining a report and appendix
- Input
- A four-page report followed by a two-page appendix
- Result
- One six-page PDF with the report first and appendix second
Pages are copied from each selected source in sequence. The original files remain unchanged.
Limits and assumptions
- Each PDF is limited to 100 MB and the selected batch to 200 MB
- Encrypted, damaged or unsupported PDFs may not open
- Large documents require enough free browser memory to hold the merged copy
Frequently asked questions
Are the PDF files uploaded?
No. The files are read and merged locally in your browser, then the result is downloaded from the same device.
What determines the page order?
The files are merged in their selected order, and pages within each source keep their original order.
Does merging change the original PDFs?
No. The tool creates a new combined file and does not overwrite the selected originals.
