Production setup
Use this checklist when deploying the website on a VPS. Some tools work with Python packages only; advanced file conversions need extra server software.
Install only the packages needed for the categories you will enable publicly.
Tools: merge, split, rotate, extract, remove pages, watermark, page numbers, protect/unlock, metadata
Python: pypdf, PyMuPDF, reportlab
Server software: qpdf, ghostscript, poppler-utils
Most core PDF tools work with Python packages. qpdf/ghostscript/poppler improve repair, compression, image export and production reliability.
Tools: OCR PDF, scanned PDF to text, image OCR
Python: ocrmypdf, pytesseract
Server software: tesseract-ocr, tesseract language packs, ocrmypdf
Install language packs for the languages you want to support, for example tesseract-ocr-eng and tesseract-ocr-urd.
Tools: Word to PDF, Excel to PDF, PowerPoint to PDF, Office converters
Python: python-docx, python-pptx, openpyxl
Server software: LibreOffice, pandoc, unoconv
LibreOffice is required for reliable DOCX/XLSX/PPTX to PDF conversion on a VPS.
Tools: image convert, compress, crop, resize, SVG, HEIC/AVIF/WebP advanced formats
Python: Pillow, PyMuPDF
Server software: ImageMagick, libvips, librsvg2-bin, webp, jpegoptim, optipng, pngquant
Pillow handles common JPG/PNG/WebP. ImageMagick/libvips/librsvg extend production image format coverage.
Tools: video convert, compress, trim, extract audio, audio convert
Python: None required for command execution
Server software: FFmpeg, FFprobe
FFmpeg is required for real video/audio conversion and compression.
Tools: zip, unzip, 7z, rar/tar/gzip/bzip archive workflows
Python: zipfile/shutil built-in
Server software: p7zip-full, unzip, zip, unrar-free
Python handles ZIP. 7-Zip and archive utilities improve multi-format archive support.
Tools: EPUB, MOBI, AZW, PDF ebook conversion
Python: None required for command execution
Server software: Calibre ebook-convert
Calibre is the standard VPS backend for ebook conversion.
Tools: DWG, DXF, SVG, PDF vector/CAD conversion helpers
Python: ezdxf optional
Server software: FreeCAD, LibreCAD, OpenSCAD, Inkscape, ODA File Converter optional
CAD is the heaviest category. DWG usually needs ODA File Converter or another licensed/approved converter. DXF/SVG workflows can use FreeCAD/Inkscape/OpenSCAD depending on format.
Tools: website to screenshot, website to PDF
Python: playwright optional
Server software: Chromium/Chrome, Playwright browsers, wkhtmltopdf optional
Browser-based rendering is required for modern website screenshots.
Tools: SSL Certificate Generator, hash tools, security utilities
Python: cryptography
Server software: certbot, openssl
cryptography generates CSR/private keys. Certbot creates trusted Let's Encrypt certificates on live VPS.
Tools: direct public URL downloader, social/link helpers
Python: requests/http libraries, BeautifulSoup
Server software: No bypass software included; official APIs may be needed
Only public, permitted, direct links should be downloaded. Do not bypass login, private content, paywalls, DRM or platform restrictions.
Tools: SEO generators, writing helpers, text tools, business templates
Python: local rule/template logic
Server software: Optional Ollama/llama.cpp for advanced local AI
Current standalone AI-style tools work without paid APIs. Advanced ChatGPT-level generation requires optional local model server or external API.
Review the command before running because full conversion support installs many packages.
