Keep your selected order
Choose files in reading order for a quick assembly. The first file appears first, followed by the next file. Check the list before starting because file selection order can vary by device.

Separate files. One complete document.
Turn a cover page, a report and its appendices into one PDF. Arrange whole documents in the list before merging. This tool joins existing pages; it does not rewrite, compress or enhance their contents.
How to merge PDF files
Add your PDFs
Select 2–20 PDFs, up to 100 MB and 1,000 pages in total. Each file is checked before it enters the list. Remove password protection and flatten forms beforehand.
Arrange the file order
Use the up and down arrows to put whole files in order. Add another PDF or remove an unwanted one. All pages within a file keep their existing order.
Merge and download
Sign in, confirm the list and start merging. Keep this page open while the files upload and process. Download the final PDF; 2 credits are charged only after a usable result is ready.
Choose the order that fits your document
The list determines where each document begins. Every page in each file is included.
Build a custom sequence
Move a cover to the top or place appendices after the main report. The arrows move complete files, not individual pages. To include selected pages only, split the source PDF first.
Combine PDFs without rebuilding their pages
Whole documents in one PDF
Merge existing PDFs without converting their pages to images. Text and graphics stay on the original pages. This does not add OCR, improve scan quality or reduce file size.
Clear limits before upload
The file list shows names, page counts and sizes before you start. Use up to 20 files, 100 MB and 1,000 pages in total. Unsupported or protected PDFs must be exported again first.
Review before sharing
Download a single PDF after processing and check its order and appearance. Document-level bookmarks, digital signatures and interactive forms are not guaranteed to survive merging. Keep your original files.
One file for the next step
Only upload documents you are authorized to process. Check the downloaded file before sharing it.
Reports and appendices
Place the main report first and add supporting PDFs afterward. Recipients can read the full packet in one file. Check page references after merging because document positions change.
Application materials
Combine a cover letter, résumé and supporting certificates in the required order. Upload only material you have permission to process. Review personal details and the final file before sending.
Scanned documents
Join separate scanned PDFs into a continuous file. Pages keep the quality of the originals; merging does not enhance faded text. Use scan enhancement separately when you need clearer pages.
Frequently Asked Questions
How are the PDFs ordered?
The visible list defines the order of whole files. Use the arrows to change it; pages inside a file remain in their original order.
Can I merge selected pages only?
This tool includes every page of each file. Split or extract the required pages first, then add those PDFs here.
Do I need to sign in or pay?
Yes. Online merging requires sign-in and costs 2 credits per successful merge, regardless of the number of files. Failed tasks and empty results are not charged.
What are the limits?
Add 2–20 PDF files, with a combined size of up to 100 MB and no more than 1,000 pages. The final downloadable PDF must be nonempty and within 200 MB.
Are encrypted PDFs or forms supported?
Remove password protection and flatten interactive forms before adding your PDFs. This page does not ask for document passwords.
Will merging change quality or size?
The tool joins existing pages without intentional image compression or scan enhancement. Output size can differ from the sum of the inputs. Bookmarks and digital signatures may not remain valid.
What happens if my connection drops?
Use Retry on this page to continue the original submission. Uploaded files and task references stay in memory for same-page recovery. Do not refresh while processing.
Will my files remain after refreshing?
No. Refreshing resets this page to file selection and removes the visible task and result. An already dispatched online task may still finish. A new submission replaces an unfinished workflow; save your download first.
