CloudConvert Audio Converter is an online service for converting audio files through a web application or API. It supports AAC, AC3, AIF, AIFC, AIFF, AMR, AU, CAF, DSS, FLAC, M4A, M4B, MP3, OGA, OPUS, SF2, SFARK, VOC, WAV, WEBA, WMA, and other listed types. Conversion controls let users adjust audio quality and file size, and batch conversion is available. CloudConvert serves individual users and corporate customers through its API. Automation integrations include Zapier, Make, Microsoft Power Automate, and n8n; storage workflows can involve Amazon S3, Google Drive, Dropbox, OneDrive, and SharePoint. API v2 includes official PHP, Node.js, Python, Ruby, Java, and.NET SDKs plus a CLI. The free plan costs nothing, with 10 credits per day, a 1 GB file limit, five-minute processing limit, five concurrent tasks, and low processing priority. Package, Subscription, and Enterprise plans list prices as “...” or custom. CloudConvert says files are processed in isolated containers and deleted afterward.

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.
