Common mistakes
- ✗Merging in the wrong order — arrange files first, the output keeps that exact sequence.
- ✗Merging password-protected PDFs — unlock them first or the merge can fail.
- ✗Forgetting that merged files keep original page sizes — mixed A4/Letter can look odd.
Tips that actually help
- ✓Name files 01, 02, 03… before uploading so they merge in order automatically.
- ✓Combine the cover letter and CV into one PDF so nothing gets separated.
- ✓If a file won't merge, open it and re-save — corrupted or empty PDFs are usually the cause.
