How to use Merge PDF
- Drop two or more PDFs in the upload area, or click to choose them.
- Reorder them with the arrows until they are in the sequence you want.
- Press “Merge PDFs” and save the resulting file.
Tips and limits
- Password-protected PDFs cannot be merged: remove their protection first.
- Pages are copied as they are, not turned into images, so the text stays selectable.
- Bookmarks and form fields from the original documents may not be kept in the final file.
What it is for and how it works
Merging PDFs means copying the pages of several documents into a new one, in the order you arrange them. It is handy for sending a complete file as a single attachment, submitting an application with all its annexes, or archiving a month of invoices.
This tool uploads nothing: it reads each file into your browser’s memory, builds the combined document and offers it as a download. That is why it works even with confidential documents, although you should always use a device you trust.
Frequently asked questions about Merge PDF
Is quality lost when merging?
No. The pages are copied into the new document without being recompressed.
How many files can I merge?
There is no fixed limit. It depends on your device’s memory; on a phone it is best to start with a few files.
Where are my documents stored?
Nowhere: they never leave your browser and disappear when you close or reload the page.
