Combining PDFs is useful when a report, application or handout has been saved as several files. A single document can be easier to review and share, as long as the pages are in a clear order.
Before you merge
Make a short list of the files you need and decide on the sequence. For example, put a cover page first, the main document next and appendices at the end. Rename files temporarily if that helps you keep track. If the originals contain sensitive information, store them somewhere appropriate and share the merged copy only with intended recipients.
Merge PDFs with PDFSathi
- Open the Merge PDF tool.
- Select two or more PDF files from your device. Add them in the desired reading order.
- Review the file list, then choose Merge PDFs.
- Open the downloaded result and check its page order and appearance.
What to check in the combined PDF
Scroll through the start, middle and end of the output. Check that pages are upright, all intended files appear, and no blank page or duplicate section slipped in. If your PDFs have fillable fields, signatures, bookmarks or unusual embedded content, test those carefully: merging can change how interactive features behave.
Can PDFs with different page sizes be combined?
Yes. A merged PDF can contain pages of different sizes and orientations. That is often fine for reading on screen, but the result may feel less consistent when printed. If print consistency matters, check page sizes before combining.
Frequently asked questions
Does merging lower PDF quality?
PDFSathi copies pages into a new file rather than taking screenshots. Page content is generally retained, though some interactive features or document metadata may not transfer exactly. Always review important files.
Can I merge a PDF and a Word document?
This tool accepts PDF files. Save or export the Word document as a PDF first, then include it in the merge.
