gs-batch-pdf vs HTTPie

gs-batch-pdf is a free, MIT-licensed command-line tool for processing PDF files in parallel on Windows, Linux, and macOS. It applies Ghostscript presets including /screen, /ebook, /printer, /prepress, and /default, and converts files to PDF/A-1, PDF/A-2, or PDF/A-3. Correct PDF/A-2 and PDF/A-3 conversion requires Ghostscript 10.04.0 or newer. Recursive directory processing can report progress for each file. You can keep the smaller result or always keep the newly processed file, add filename prefixes or suffixes, and choose whether failures prompt, skip, or abort. Silent options support unattended runs, including forced overwrites, suppressed output-folder opening, and skipped errors. Arbitrary Ghostscript options are accepted. Python 3.12 or later and a separately installed Ghostscript executable are required; pipx is recommended, while pip is also supported. No API access is listed.

HTTPie is an API testing client with a command-line tool and a graphical app for desktop and web. HTTPie for Terminal helps test and debug APIs, HTTP servers, and web services. Its features include expressive syntax, JSON, formatted and colorized output, persistent sessions, forms, file uploads and downloads, HTTPS, proxies, authentication, and custom request data and headers. GraphQL is supported. The Desktop and Web app includes AI-assisted work, spaces, collections, tabs, variables, environments, request previews, and autosave with realtime sync across devices. It can be used offline without an account, so requests can be prepared and previewed without sending them. Dedicated desktop versions are available for Mac, Windows, and Linux; Mac downloads cover Intel and Apple Silicon. The maker lists CLI installation options for any operating system. HTTPie for Web & Desktop is in public beta, and HTTPie for Terminal is an open-source CLI client. Both plans are listed at free.
