Tired of juggling multiple PDF files? Whether you're combining invoices for accounting, merging research papers for submission, or consolidating legal documents, our PDF merger makes it simple. No software to install, no watermarks added, and it works right in your browser.
The best part? You control the order. Drag and drop your files to arrange them exactly how you want. Need to add more files? Just upload them. Want to remove a page? Delete it before merging. Everything happens instantly, and your original files stay untouched.
When Do You Need to Merge PDFs?
Business professionals often merge monthly reports, quarterly statements, or project documentation into single files for easier sharing. Students combine multiple assignment PDFs before submission. Legal teams merge contracts, amendments, and supporting documents for court filings. The possibilities are endless.
Our tool handles everything from two-page documents to hundreds of pages. The merged file maintains all formatting, so your tables, charts, and images look exactly as they did in the originals.
Your Documents Stay Private
Privacy matters, especially with sensitive documents. That's why all merging happens locally in your browser. Your files never upload to any server—they stay on your device until you download the final merged PDF. Once you're done, we don't keep any copies.

Tips for Best Results
Before merging, make sure all your PDFs are in the right order. You can preview each file and rearrange them easily. If you have very large files (over 25MB each), consider compressing them first using our compress tool for faster processing.
The merged PDF will be the sum of all file sizes, so keep that in mind if you're combining many large documents. For sharing via email, you might want to compress the final merged file.
Common Questions About Merging PDFs
Can I merge password-protected PDFs?
Password-protected PDFs need to be unlocked first. Use our unlock PDF tool to remove the password, then you can merge them with other files.
What happens if my files have different page sizes?
The merged PDF will contain all pages at their original sizes. If you have a mix of letter and A4 pages, they'll all be preserved as-is in the final document.
How long does merging take?
Merging is usually instant for small files. Larger files (over 10MB) might take a few seconds. The processing happens in your browser, so it depends on your device's performance.
Can I undo the merge if I make a mistake?
Before downloading, you can always go back and rearrange files or remove some. Once you download, you'll need to start over if you want changes, but your original files remain untouched.
