Frequently Asked Questions (FAQ)

Q: How does the tool create bookmarks from filenames?
A: During the merge process, each input PDF is automatically added as a top-level bookmark using its original filename. You can edit these names before merging if desired.
Q: Can I merge only specific pages from each PDF?
A: Yes. For each file, you can define custom ranges like "1-15", "10-end", or even non-continuous pages. The final PDF will contain only the selected content in your chosen order.
Q: Is my data safe? Do you store any files?
A: Absolutely safe. The entire process runs locally in your browser. No files are uploaded, stored, or transmitted to any server. Once you close the page, all processing data is cleared.
Q: Will the merged PDF keep the original formatting and quality?
A: Yes. We preserve vector graphics, fonts, hyperlinks, layers, and all visual elements at 100% original quality.
