Merge PDF
Combine PDFs in the order you want.
Combine several PDF documents into a single file. Add the files in the order you want, review the list, and export a merged copy.
How to use Merge PDF
Choose PDFs
Select at least two unlocked PDF files. Use Add more to append another document.
Set the file order
Use Move up and Move down beside each file. Each document contributes all of its pages in their existing order.
Download and check
Choose Merge, open the downloaded PDF, and check the boundaries between the source documents.
Example
Choose files or choose individual pages?
Merge PDF combines complete files. To keep only pages 2–4 of a document, first extract that range with Split PDF and add the resulting file to your merge list. Removing a file from the list only removes it from this task; it does not delete your original.
Mixed portrait and landscape pages keep their original sizes and orientation. Check printing settings in your PDF viewer instead of assuming the result is all A4. Keep signed originals separately: assembling a new file does not preserve their verification status.
Continue your task
- Merge PDFs and check the final page order
- Convert a DOCX document before merging it
- Extract text from your combined PDF
What to check
Common questions
Why is Merge unavailable?
Add at least two PDFs. The export controls pause while the combined file is being created. Files in other formats are skipped.
Can I drag files to change their order?
Use the Move up and Move down buttons in the file list. Dropping files onto the upload area adds them; it does not reorder the existing list.
Why did a file fail to merge?
It may be encrypted, damaged or too complex for available browser memory. Try each document separately and use an unlocked copy you are allowed to edit.
Are original files overwritten?
No. The result downloads as merged-freetoolzhub.pdf. Your input files remain on your device.
