Converseen vs Pandoc

Converseen is a free batch image processor for Windows, Linux, macOS, FreeBSD and other operating systems. It converts, resizes, rotates, flips and compresses images, and renames groups using progressive numbers or prefix and suffix values. Through ImageMagick, it handles more than 100 formats, including DPX, EXR, GIF, JPEG, JPEG-2000, PNG, SVG, TIFF, WebP and HEIC/HEIF. It can turn a full PDF or selected pages into images with chosen dimensions and formats, and extract images from Windows icon files. Converseen is built with open-source frameworks and libraries including Qt and ImageMagick; its source is released under GNU GPL version 3. Linux installation options include source code, AppImage, Snap, Flatpak and distribution repositories. The program does not transfer information to other networked systems. The Free plan is free. Windows and Linux users need Ghostscript configured for PDF processing, and the macOS release is beta and not currently codesigned.

Pandoc is a command-line document converter and Haskell library, offered for free under the GPL. It converts among markup and word-processing formats including Markdown, HTML, LaTeX, Word DOCX, EPUB, and Jupyter notebooks. Readers parse a source into an abstract syntax tree, which writers then turn into the selected output format. Templates and Lua filters let users adjust processing, and Lua can also be used to create custom readers and writers. Pandoc formats citations and can produce bibliographies with hundreds of CSL styles. PDF output uses LaTeX by default, though users can specify another PDF engine. Installers or binaries are provided for Windows, macOS, and Linux, with package-manager and source installation also documented. It can be run through GitHub Actions or GitLab CI/CD, and official Docker images are available. The official Linux executable is statically linked without dynamic dependencies or external data-file dependencies. Pandoc has no graphical interface; conversions from more expressive formats can lose information, and complex tables may not fit its document model.
