Original Summary

Hi everyone, I'd like to share a little side project that I hope you'll find useful. Proview is an app for viewing images and PDFs, with a few extra tools for everyday tasks. I was inspired by Preview, the built-in viewer on macOS: it opens a wide range of files, lets you make basic edits to images and PDFs, and makes it easy to add a signature to a document, all through a simple interface. Since I use Linux at work, I've always wanted a similar experience on my PC. With AI tools now available, I figured I was just a couple of prompts away from building one. Proview runs on Linux, Windows and macOS , and it's free and open source under the AGPL-3.0-or-later license. It currently supports: Viewing, cropping, rotating and annotating images. PDF text highlighting, redaction, page reordering, merging and splitting. Reusable handwritten signatures: draw one or import one from a photo or scan, with automatic background removal and vectorization. Optional signature-library sync between computers using Google Drive or S3-compatible storage. Sync uploads the saved signature library; documents opened for editing stay on your computer. OCR for copying text from images and scanned documents. Viewing STL files, a common format for 3D meshes. PDF exports preserve native content: added text, ordinary shapes and vector signatures stay as vectors rather than turning the whole page into an image. I built it with help from AI tools. The app uses Go and Fyne, with MuPDF and pdfcpu for PDFs and Tesseract for OCR. Source code and screenshots · Downloads I'd appreciate any feedback. If you run into a bug, please open an issue with your OS and the steps to reproduce it.   submitted by   /u/lelettrone [link]   [comments]
