Frequently Asked Questions
Is my data safe when using this PDF merger?
Yes! All PDF merging happens entirely in your browser. Your files never leave your device and are never uploaded to any server. We cannot see your files. This makes our tool significantly more secure than online services that require uploading your documents.
How many PDF files can I merge at once?
There is no strict limit on the number of PDFs you can merge. However, for optimal browser performance, we recommend keeping the total file size under 50MB. Modern browsers can typically handle merging 10-20 average-sized PDFs without issues.
Can I reorder PDFs before merging them?
Yes! You can drag and drop PDFs to reorder them in any sequence. The final merged PDF will contain pages in the exact order you specify. This is useful when you need to organize documents in a specific sequence.
Does the PDF merger work on mobile devices?
Yes, the PDF merger works on all modern browsers including mobile devices (iOS Safari, Android Chrome). However, performance may vary based on device capabilities and the size of your PDF files. Smaller files work best on mobile.
Do you keep copies of my PDF files?
No. All processing happens locally in your browser using JavaScript. We never receive, store, or have access to your files. When you close the browser tab, all data is automatically cleared. Your privacy is completely protected.
What is the file size limit for PDF merging?
Individual files are limited to 10MB each, with a total combined size limit of 50MB. These are soft limits designed to ensure good browser performance. If you need to merge larger files, try splitting them or compressing them first.
Can I merge password-protected PDFs?
Currently, password-protected (encrypted) PDFs cannot be merged. You will need to remove the password protection first, then merge the files. This is a browser limitation for security reasons.
Does merging reduce PDF quality?
No! Our merger preserves the original quality of all PDFs. Pages are copied exactly as they are, maintaining all text, images, formatting, and metadata without compression or quality loss.
