FAQs
Is it safe? Yes. Processing happens in your browser using Web APIs and pdf-lib. No files are uploaded to any server.
Can I reorder files before merging? Use your file picker to select in order, or reselect if needed. (A drag-to-reorder UI will be added later.)
Large PDFs? Very large files can consume memory. Close other tabs/apps if you run into issues.
