Use Cases
- Combine a main contract, appendices, and pricing sheets into one PDF before sending it out.
- Merge report chapters, exhibits, and reference material into a single file for printing or archiving.
- Join scanned receipts, statements, or supporting documents into one upload-ready PDF.
- Prepare one finished attachment when a portal accepts only a single PDF upload.
How to Use
- Upload the PDF files you want to combine, or drag them onto the page.
- Reorder the files and choose which pages to keep from each PDF.
- Review the merge queue below and drag individual pages until the final order looks right.
- Start the merge and download the finished PDF when browser processing completes.
Features
- Multi-file merge: Add several PDFs and export them as one finished document.
- Per-file page selection: Keep only the pages you need from each source file.
- Two-level ordering: Reorder the file list and fine-tune the final page queue.
- Local browser processing: Your PDFs stay on your device and are not uploaded to a server.
- Instant download: Generate the result and download it immediately after merging.
- Works on desktop and mobile: Preview, select pages, and sort files across device sizes.
Merge PDF, split PDF, or extract pages?
Use merge when you need one finished document. If your real goal is to keep only part of a file, break a large document apart, or reduce the final size, another tool may get you there faster.
| Your goal | Best tool | Why |
|---|---|---|
| Turn several PDFs into one finished document | Merge PDF | Best for combining chapters, appendices, and scans into a single output file.Merge PDF |
| Keep only a few pages from a larger file | Extract pages | Pulling out the exact pages you need is faster than merging everything and cleaning it up later.Extract PDF pages |
| Make the final merged file smaller | Merge first, then compress | Compressing the finished result once is usually easier than guessing which source file to optimize first.Compress PDF |
| Break one large PDF into separate files | Split PDF | Split tools are better when you need several independent output files.Split PDF |
Best Practices
Set the reading order before you merge
Straighten out the file list and the final merge queue first so you do not have to export the same document again and again.
Select pages early when you only need part of each file
Adding only the pages that matter is usually faster than merging full files and cleaning up the result afterward.
Compress the final output if size still matters
Once you have the finished document, you can judge the real file size and compress only once if needed.
Compress PDFApply signatures or protection after the merge is final
Merging creates a new PDF, so existing signatures usually stop being valid. Finalize the combined file first, then sign or protect it.

Can I merge only some pages from each PDF?
Yes. Each file has its own page picker, so you can keep only the pages you need and leave out covers, blanks, or unrelated attachments.
Can I change both file order and page order?
Yes. The file rail controls the source file order, and the merge queue lets you drag individual pages into the exact final order you want.
Are my files uploaded to a server?
No. This page reads, previews, and merges PDFs locally in your browser. Your files stay on your device, and temporary session data disappears when you refresh or close the page.
What happens to bookmarks, signatures, or interactive forms?
This tool is focused on page merging. Because the output is a new PDF, existing digital signatures usually become invalid, and bookmarks, form behavior, or embedded extras may not carry over exactly. Check the final file before sharing it.
How many PDFs can I add at once?
The current page accepts up to 10 PDF files per batch. If you need more, merge one batch first and then merge that result with the remaining files.
What if the merged PDF is still too large?
Remove pages you do not need first, then compress the finished result if the file is still too big. If the sources are image-heavy, shrinking the original images can also help.
Current page capabilities and limits
These are the key actions the page supports right now and the practical limits to expect.
| Item | Current behavior | Notes |
|---|---|---|
| File count | Up to 10 PDFs per batch | Merge in rounds if you need more |
| Page selection | Per-file page picking | Skip covers, blank pages, or unrelated attachments |
| Ordering | File order plus merge-queue order | The final queue decides the output order |
| Processing | Runs locally in the browser | Speed depends on device memory and file size |
| Sensitive documents | Not uploaded to a server | Useful for contracts, finance, and internal material |
Which tool fits the task best?
If your real goal is not pure merging, one of these paths may save time.
| Task | Recommended tool | Why |
|---|---|---|
| Submit only a few pages | Extract pages | Pull out the exact pages you need and skip an extra merge step |
| Reduce the final file size | Compress PDF | Shrink the finished output once instead of guessing at the sources |
| Turn image material into PDF first | Images to PDF | Create PDF source files from pictures before merging them |
| Produce several separate documents | Split PDF | Split is better when the output should be multiple files |
