Working with multiple separate PDF files is inconvenient: documents get lost, order gets mixed up, and it's difficult to send to a colleague or upload to a system. Merging PDFs solves these problems — you get one neat document.
Reports and presentations — combine multiple parts into a single document for sending
Scanned documents — merge page-by-page scanned files
Study materials — gather notes, lectures and assignments in one file
Legal documents — bundle contracts with appendices
Open [Merge PDF](/tools/merge-pdf)
Drag and drop files into the upload area or click to select
Rearrange file order if needed (up/down buttons)
Click "Merge" and wait for the result
Check the preview and download the finished file
Privacy — files never leave your browser, nothing is uploaded to a server
No limits — merge any number of files
Fast — processing takes seconds
No registration — no account needed
Check page order before merging
For large files (50+ MB), consider compressing each PDF first
The merged file preserves all bookmarks and links from originals
**How many files can I merge at once?**
There's no limit — it depends only on your device's RAM. In practice, 20-30 files are processed instantly.
**Are bookmarks and links preserved?**
Yes, internal links and structure of each document are preserved when merging.
**Is this safe?**
Absolutely. All files are processed locally in your browser using JavaScript. Not a single byte is sent to our or any other server.
