Privacy & Security
BriskTool's PDF merger runs entirely in your browser using pdf-lib.js. Your files are never uploaded to any server - they're processed locally on your device. This makes it safe for sensitive documents like contracts, financial records, and legal files.
Tips for Better Results
- Check page orientation - If some pages are landscape and others portrait, they'll merge as-is
- Compress after merging - The merged file might be large. Use the PDF Compressor to shrink it
- Preview the order - Make sure your pages are in the right sequence before merging
Common Questions
Is there a limit on how many PDFs I can merge?
No hard limit. You can merge as many files as your browser's memory allows. For very large merges (50+ files), consider doing it in batches.
Will merging affect the quality of my PDFs?
No. Merging simply combines the pages - no re-encoding or compression is applied. Every page retains its original quality.
