PDFSwifter — All-in-One Document Toolkit

Mohamed came with a straightforward brief: build a document-tools platform that can stand next to the ones people already use. PDFSwifter is that platform — PDF and media utilities over an API-first core, which I built, deployed and handed over. He runs it now; I do not, and it would be easy but wrong to imply otherwise on a site whose whole argument is that I stay.

The established document tools are a crowded field, and a new entrant cannot win on having one clever feature. It had to cover the operations people actually arrive for, be quick enough that nobody thinks about it, and be built so new tools could be added without rebuilding the thing each time.

A modular tool suite over a Python FastAPI backend, with each utility behind its own endpoint so the web app and any later client consume the same API. Deployed with Docker behind Caddy, using Redis for job state, so processing work does not block the request that started it.

• Unified many document utilities into one cohesive platform.
• API-first architecture to support web and future clients.
• Expanded into YouTube/TikTok media conversion tools.

• Designed and implemented the FastAPI backend in Python.
• Structured modular utilities for PDF processing and media conversion.
• Created API endpoints to support automation and future integrations.
• Deployed and ran the platform: Docker, Caddy, Redis, on the client’s own domain.

• Core PDF tools for merging, splitting, compressing, and converting files
• Media conversion utilities for YouTube and TikTok formats
• API-first architecture using FastAPI
• Extensible structure for adding new tools

• Keeping the toolset modular as the feature list expanded.
• Balancing usability with the technical depth of multi-tool workflows.
