File Viewer Plus review
A broad Windows file utility with viewing, editing, inspection, and batch conversion.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
File Viewer Plus is a Windows desktop utility for opening, viewing, editing, and converting files across more than 400 formats. It is aimed at individual users, businesses, and enterprise teams that want one application for office documents, PDFs, images, audio, video, archives, email files, CAD drawings, source code, markup, and medical images. Its coverage makes it a fit for Windows users who regularly encounter varied file types and want viewing or conversion tools without installing separate applications for each format.
The feature set is broad rather than limited to a single file category. Microsoft Office documents can be viewed and edited, while PDFs can be viewed, annotated, and converted. The product also supports image editing, audio and video playback and conversion, archive browsing, and source-code or markup preview with syntax highlighting. For technical inspection, it can expose file headers, metadata, and raw hex content. Batch conversion of folders is useful for users handling repeated format changes, while search within files is included in the category specifications.
According to the vendor's published plans, the Annual Subscription costs €22 per user per year and includes all 400+ formats, continuous version updates, two years of free support, installation on two PCs per household, and a 30-day money-back guarantee. The One-Time Purchase costs €45 per user and includes all 400+ formats, version 6.x updates, two years of free support, installation on two PCs per household, and the same guarantee. Enterprise / Volume licensing adds volume pricing for five or more seats, centralized license management, priority support, an MSI installer, invoice and PO acceptance, and a dedicated account manager. A 14-day trial is available. Choose it for broad Windows file handling; choose an alternative if you need Android access.
