Proview

Proview is a simple desktop app for viewing and making basic edits to common file formats including images, PDFs, and 3D STL files on Linux, Windows and macOS. It supports image cropping, rotating, annotating, PDF text highlighting, redaction, page manipulation, reusable handwritten signatures with optional cloud sync, and OCR text extraction. Proview preserves native PDF content when exporting and offers a user-friendly interface inspired by macOS Preview.
