Merge chapters, slides, or sections from different sources into a unified presentation or report.

🗂️ Project Files
Consolidate research papers, meeting notes, and reference materials into a single project document.
Tips for Merging PDFs
- ✦Plan your order first. Think about the logical flow before uploading. It's easy to reorder, but starting organized saves time.
- ✦Check page orientations. If some PDFs are portrait and others landscape, they'll merge as-is. Consider rotating pages first if uniformity matters.
- ✦Use descriptive filenames. Name your merged PDF clearly (e.g., "Q4-2024-Financial-Reports") so you can find it later.
- ✦Preview before merging. Use the thumbnail previews to verify you have the right documents in the right order before combining.
- ✦Compress if needed. If the merged PDF is too large, consider compressing the source files first or using a PDF compressor afterward.
