Quick Alternatives by Operating System
| System | Tool | Best For |
|---|---|---|
| Windows | PDFsam Basic | Splitting and merging large batches |
| Mac | Preview (built-in) | Simple annotations and signatures |
| Linux | Okular | Lightweight annotation without extra installs |
PDFsam Basic sits on the Windows taskbar and lets you drag files into merge or split queues. Preview on Mac already supports markup, so most users never need another program for one-off comments. Okular on Linux opens PDFs in the file manager and adds highlights without launching a full office suite.
Test each option on a copy of your actual documents first. The right choice usually becomes obvious after two or three files.
