About 合并 PDF
直接在浏览器中使用此工具，提供清晰选项，并在可用时进行本地隐私处理。 Use it when you need the result without the overhead of opening a larger application. For anything important, compare the output with your source and keep the original until you are satisfied with the result.
A cleaner way to assemble a document package
Merging is most useful when several files belong to one task: a signed form plus evidence, chapters of a report, or scans that need to arrive as one attachment. The difficult part is rarely the merge itself; it is making sure the finished file tells the same story as the source set.
Before downloading, put the files in the order a recipient would expect. After the merge, open the new PDF and verify the first page, last page and total page count. If the PDFs are scans, look at orientation and readability before you delete or archive the originals.
A realistic example
If an application requires a cover sheet, a three-page form and two receipts, merge them in that reading order and confirm the result has six pages before uploading it.
When this tool is not the right fit
If the files contain information you are not allowed to process in a browser workflow, use an approved local or organizational PDF process instead.
