Merge PDF Files Into One
An application with a CV, cover letter and certificates, a monthly bundle of invoices, chapters of a report from different people – all of them should end up as one PDF. Add the files, put them in order and merge them into a single document.
The merge runs in your browser, so contracts, IDs and other personal documents are never uploaded.

Merging in the right order
The order of the files in the list is the order of the pages in the merged PDF. Use the arrows or drag the files to sort them before you merge – for example cover letter first, then CV, then certificates. Each file keeps its own pages in their original order.
What the merged PDF contains
- All pages of all files, one after another, unchanged in quality.
- Text stays selectable and searchable, images keep their resolution.
- Pages in different sizes or orientations are kept as they are.
- Bookmarks and form fields of the single files are not carried over.
Before you send the merged file
Merged PDFs can get large. If an upload form or email has a size limit, compress the merged PDF afterwards. To remove single pages from the result, use the PDF editor. Password-protected PDFs have to be unlocked before they can be merged.

Merge PDF – questions and answers
How do I merge PDF files?
Add two or more PDFs, put them in the right order with the arrows or by dragging, and click “Combine PDFs”. You download one merged PDF.
Is merging PDFs the same as combining PDFs?
Yes. Merge and combine mean the same: several PDF files become one. This page uses the same tool as Combine PDF.
Does the quality change when I merge PDFs?
No. The pages are copied unchanged, so text and images look exactly like in the original files.
How many PDFs can I merge?
There is no fixed limit on the number of files; each PDF can be up to 100 MB.
Are my files uploaded when I merge them?
No. The PDFs are merged in your browser and stay on your device.
