File Viewer Plus
What it is
File Viewer Plus is a Windows desktop application for opening, viewing, editing, and converting more than 400 file formats. It can edit Office documents, annotate PDFs, convert PDFs into editable DOCX files, and display syntax highlighting for more than 80 programming languages. Image tools support more than 50 formats, including RAW, with options to crop, resize, rotate, adjust color, and apply filters. The app also plays more than 150 audio and video formats, opens DWG and DXF drawings, and browses ZIP, 7Z, RAR, TAR, and JAR archives. CAD and DICOM files are view-only, though they can be exported to common image formats. A batch converter processes folders and reports successful conversions, skipped files, and errors. It supports command-line file opening; command-line batch conversion is available under the Enterprise license. The maker also offers a separate free Android app that opens more than 150 file types. The annual subscription costs €22 a year, or a one-time purchase costs €45. The maker says opened and edited files remain on the user's device and their contents are not collected.
