Tips for Merging PDFs
- Check page order before merging — preview the file order before clicking merge.
- Consistent page sizes: if merging documents of different page sizes (A4 and Letter), the merged PDF will contain both sizes — normalize if needed.
- File size consideration: the merged PDF size will be roughly the sum of all input files.
