## ToolGPA grades

**GPA: 2.8 out of 4**, graded Nov 13, 2026. SumatraPDF is a free, open-source reader for PDF, EPUB, MOBI, comic, DjVu, XPS and CHM files, with a portable build. It only reads, so it will not edit a PDF, and the desktop app is Windows only.

- **Value for money: A.** Free and open source, with no ads or bundled software, and anyone can download and run it.
- **Free plan and trial: A.** The whole app is free to download and use, with nothing held back.
- **Features: D.** It opens many document formats but the pages list no editing, so for a PDF editing category it covers one narrow function, viewing.
- **Ease of use: B.** No store rating is on record, but you install or unzip it and open a file, with nothing to set up.
- **Platforms and integrations: C.** A Windows desktop app in 32-bit, 64-bit and ARM64 builds, plus a browser version. There is no Mac, Linux or phone app.

## Keep it, or make your own?

**Keep it.** SumatraPDF is free, so making your own would save you nothing. It is one of the better ones too: its GPA of 2.8 is higher than 31 of the 45 other PDF editors we grade.

- You could make: Documents: an app builder makes this well.
- You could not: A real app for Windows. Something home-made would be a web page.
