Frequently Asked Questions
How do I merge PDF files?
Upload or drag and drop your PDF files into the tool. Reorder them if needed, then click Merge PDF. Your combined document downloads instantly.
Is it safe to merge PDFs online?
Yes. This tool processes everything in your browser. Your files are never uploaded to any server, so your documents stay completely private.
Is there a file size limit?
There is no fixed limit. Since processing happens in your browser, performance depends on your device. Most users can merge documents up to 100 MB without issues.
Can I reorder pages before merging?
Yes. You can drag and drop files into any order before merging. The final PDF follows the order shown in the list.
What happens to my files after merging?
Nothing is stored. Your files exist only in your browser memory while you use the tool. Once you close or refresh the page, they are gone.
Can I merge password-protected PDFs?
The tool attempts to load PDFs with encryption handling enabled. Unencrypted and owner-password-protected files typically work. User-password-protected files that require a password to open may not load.
Is this tool free to use?
Yes, completely free with no limits. No account, no watermarks, no daily caps. Use it as many times as you need.
