How to merge PDF files online
Combine multiple PDFs into one file in your browser. Order pages, keep quality, and download instantly.
Upload every file you need
Open Merge PDF and add two or more PDF files. Drag them into the order you want before you run the job. The merged file keeps the original page quality.
Reorder or remove pages later
If you need a different page sequence after merging, use Organize PDF to reorder or delete pages without starting over from scratch.
Split when you need the reverse
Need one document broken into smaller files? Split PDF can extract page ranges or split every N pages into separate downloads.
Keep names and order straight
Rename files before you merge if the output filename matters for clients or courts. Drag the stack into the final reading order in the merge list so you do not have to rebuild the document later.
When merge is the wrong tool
If you only need a few pages from each file, extract those ranges with Split or Organize first, then merge the smaller files. That keeps the result shorter and avoids dragging unused pages into the new PDF.
Questions
- Does merging reduce quality?
- No. Merge concatenates pages. Image resolution and fonts from each source PDF are preserved.
- Can I merge password-protected files?
- Unlock each protected file first with Unlock PDF (when you know the password), then merge the unrestricted copies.
