Fusionner PDF FAQ
Yes, security is our priority. Your files are processed using encrypted connections (SSL) and are never stored permanently. We employ an automated deletion policy that wipes all uploaded data from our servers after 30 minutes.
You can upload and merge multiple files in a single session. While there is no strict limit on the number of files, we recommend keeping the total batch size reasonable (under 100MB) for the fastest processing speeds.
Absolutely. Once you upload your PDFs, you can see them in a list. Simply delete any unwanted files or clear the list to start over. The tool merges them in the order you upload them, so add them in your desired sequence.
No. Our merge tool is designed to preserve the original quality of your source documents. It simply stitches the pages together without re-compressing or degrading the images or text.
This specific tool is designed for PDF-to-PDF merging. If you have images (JPG, PNG) that you want to include, we recommend converting them to PDF first using our specific converter tools, and then merging the resulting PDFs here.
For security reasons, we cannot process encrypted files without the password. You must unlock the file first (using our Unlock PDF tool if you have the right to do so) before adding it to the merge queue.
No. The final output file is completely clean and watermark-free, even for free users. We believe in providing a professional-grade tool without aggressive branding.
