Filee
Free, open-source file converter: 263 formats, offline, drag and drop
Filee is a free, open-source file converter for Windows, macOS and Linux. Hold a key while dragging files and a ring of presets (the donut) appears at the cursor: drop the files on one and they're converted on your own PC. Nothing is uploaded. It handles 263 formats: pictures, PDF, Word, Excel, PowerPoint, Korean HWP/HWPX, Chinese OFD, video, audio, e-books, archives, CAD drawings, 3D models, maps and more. The engines it needs come bundled or are downloaded on demand from their official sources. Presets can resize and compress, add a watermark, page numbers or a password to PDFs, remove metadata, fit a file under a size limit for email or chat, and replace the original. Watch folders convert new files on their own, and a "filee" command does the same from scripts. The interface speaks 16 languages. MIT licensed; Windows releases are code-signed. -

Dompdf
HTML to PDF converter for PHP
dompdf is an HTML to PDF converter. At its heart, dompdf is (mostly) a CSS 2.1 compliant HTML layout and rendering engine written in PHP. It is a style-driven renderer, it will download and read external stylesheets, inline style tags, and the style attributes of individual HTML elements. It also supports most presentational HTML attributes. PDF rendering is currently provided either by PDFLib or by a bundled version the R&OS CPDF class written by Wayne Munro. (Some important changes have been made to the R&OS class, however). In order to use PDFLib with dompdf, the PDFLib PECL extension is required. Using PDFLib improves performance and reduces the memory requirements of dompdf somewhat, while the R&OS CPDF class, though slightly slower, eliminates any dependencies on external PDF libraries. -
