Combining multiple PDFs into one file is done with a merge tool: upload all the separate PDFs, arrange them in the order you want them to appear in the final document, and combine them into a single file. This is common when a portal (like a visa or job application) specifically requests one combined document rather than several separate files. Merging doesn't reduce quality or alter the original content - it simply combines the existing pages as-is into one file.

Frequently Asked Questions
Does merging PDFs reduce file quality?
No - merging combines pages as-is without recompressing them.
Can I combine PDFs and images into one file?
Typically yes, though images may need to be converted to PDF first using an image-to-PDF tool before merging.
Is there a limit to how many files can be merged at once?
There's usually a generous limit suited to typical multi-document submissions.
Can I reorder pages after merging if I got the order wrong?
You'd generally need to re-merge with the files in the correct order, or use a separate tool to reorder pages afterward.
Does merging work on mobile devices?
Yes - the tool runs in your browser, so it works the same way on a phone as on a desktop.
