How many PDF files can I merge at once?
You can merge as many PDFs as you need. However, very large batches (50+ files) may take longer to process depending on your device's speed. For best performance, we recommend merging 10-20 files at a time.
Will the merged PDF preserve formatting and quality?
Yes! The merger preserves all formatting, fonts, images, and quality from the original PDFs. The merged document will look exactly like the individual files.
Can I change the order of PDFs before merging?
Absolutely! Use the up (↑) and down (↓) arrows next to each file to reorder them. The files will be merged in the order shown in the list.
Is it safe to merge confidential documents?
Yes! All processing happens in your browser. Your PDFs never leave your computer, making this tool perfect for confidential or sensitive documents.
