Common uses
Combining scanned tax documents into one submission, merging a cover letter with a resume for a single application file, assembling chapters of a report from different contributors, or joining multiple invoice PDFs into one file for accounting — all common cases where several separate PDFs need to become one.
FAQ
Is there a limit to how many files I can merge?
No artificial limit — very large batches may just take longer to process since everything runs in your browser.
Can I reorder pages after merging?
Arrange files in your desired order before merging; for page-level reordering within the merged file, you'd need a dedicated PDF page editor.
Does merging affect the quality of scanned pages?
No. Merging combines the existing PDF pages as-is without re-rendering or recompressing their content.
