What is the TradeNovaTech PDF Merger?
TradeNovaTech's PDF Merger is an online tool for combining multiple PDF files into a single PDF document. It is designed for workflows where documents need to be collected into one file while keeping control over which pages are included and the order in which the files are merged.
The tool supports up to 50 PDF files with a combined upload limit of 200 MB. You can enter page ranges for individual files, reorder the files before merging, and provide a custom output filename.
At a glance
Minimum 2 PDF files are required. The final filename is required, and the tool automatically adds the .pdf extension to the output name.
How to Merge PDF Files
Select your PDF files
Drag and drop PDF files into the tool or click the file-selection area to choose them from your computer. You can select up to 50 PDFs, provided the combined size stays within 200 MB.
Choose the pages you need
Each file can use a page range. Enter 1-5 to include pages 1 through 5, 1,3,7 to choose specific pages, or leave the range as all to include the whole document.
Reorder the files
Arrange the files in the order you want them to appear in the final PDF. The merge follows the order shown in the file list.
Enter an output filename
Enter the name you want for the final document. The filename is required and .pdf is added automatically.
Merge and download
Select Merge & Download. The tool processes the request and generates the combined PDF for download.
Page Range Examples
| Input | Meaning | Example use |
|---|---|---|

Privacy and File Processing
PDF files are uploaded securely over HTTPS and processed temporarily on the TradeNovaTech server for the merge request. The tool states that uploaded files are not intentionally retained after processing.
Important
This is a server-processed PDF merger. Do not confuse it with TradeNovaTech's separate Free PDF Merger, which uses browser-local PDF processing.
Large PDF Files
The tool notes that large PDFs, including documents with 100 or more pages, may take some time to process. Keep the page open while the merge request is being completed and wait for the result.
Troubleshooting
Only one PDF is selected
At least 2 PDF files are required to start a merge. Add another PDF before selecting the merge action.
The total file size is too large
Check the total size shown by the tool. Remove one or more files or reduce the amount of material being merged so the combined upload stays within 200 MB.
The page range is rejected
Check the page-range format. Use formats such as 1-5, 1,3,7, or all, and correct the range before starting the merge.
The output filename is missing
Enter a filename before merging. The tool requires an output name and adds the .pdf extension automatically.
The result takes longer than expected
Large PDFs can take additional processing time. The tool specifically notes that documents with 100+ pages may take some time, so keep the page open and wait for completion.
PDF Merger vs Free PDF Merger
TradeNovaTech currently provides two PDF merging tools. They solve a similar problem but use different processing models and feature sets.
| Feature | PDF Merger | Free PDF Merger |
|---|---|---|
| URL | /merge-pdfs | /merge-pdf-free |
| Processing | Server-side | Browser-local |
| Maximum files | 50 | 25 |
| Combined size limit | 200 MB | 500 MB |
| Page selection | Yes | No |
| File reordering | Yes | Yes |
Which one should you use?
Use PDF Merger when you need page-range selection and server-side processing. Use Free PDF Merger when you prefer browser-local processing and do not need page selection.
