knifelemon/filee v1.12.0 is a release that adds converting PDFs into PPTX files with image slides and compressing PDFs. The v1.12.0 release notes on GitHub also list video frame extraction and hardware encoding support as new features. Hardware encoding is off by default.
filee is a free, open-source tool that converts more than 180 formats offline simply by dragging and dropping files. According to the repository description, it handles images, PDF, Word, Excel, PowerPoint, HWP/HWPX, video, audio, e-books, and archive files, and it converts them without uploading your files. The repository description also notes that Office is not required. For users who want to work with many file formats in one place, this update adds document conversion and video processing capabilities together. That scope covers not only office files such as documents, spreadsheets, and presentations, but also media, e-book, and archive formats.
However, hardware encoding is not enabled in the default settings. The release information provided gives no figures for judging whether the PDF conversion output is editable, and no numbers for compression ratio, conversion speed, or quality. So it is hard to conclude anything about the concrete results or performance of the new features from this information alone; what can be confirmed is limited to the feature additions and the default settings.
