SumatraPDF

This is useful for manuals, books, comics and ordinary PDFs on Windows. It suits you if reading is more important than extensive editing. For specific form or signing tasks, check that the required function is present before replacing another program.

Open a few document types that you often use. Set the reader as default only for the formats you want to open with it.

You can read local documents without uploading them to an online viewer. Note the history of recently opened files when others use your account. Links in documents can open your browser and visit a website. So treat an unknown link as carefully as a link from e-mail.

You don't get an extensive PDF editor. For complicated forms, signature or text editing you may need another program.

A portable version is not automatically lost: documents and settings can still be on the used device. Check a printed document on scale and completeness. In case of a function that does not work properly, use an appropriate PDF app instead of assuming that the file itself is defective.

SumatraPDF is a targeted choice if you want to read documents with a compact Windows reader. You can also open different e-book and comic strip formats in addition to PDF. The emphasis is on access to content. Compare what you need first: reading and navigating is a task other than filling in complicated forms or editing a document in content.

The app is a good match if read, search and navigate your recurring tasks are. Check your own document with bookmarks and a print on the right scale. If you need extensive annotation or complex form functions, let those requirements determine the choice. A compact reader is not automatically the right tool for every operation to the same file type.
