Convert almost anything to PDF with http://pdfitdown.app!
I recently released PdfItDown v3, the library I built to convert most file formats to PDF. Now it has a full-stack web app too :)
The frontend is built with @tan_stack and deployed on a @Cloudflare Worker, with @WorkOS handling authentication and @posthog powering analytics
The backend runs on @FastAPI, deployed as a @Docker image on @Railway. It uses @upstash Redis for rate limiting and @opentelemetry + @AxiomFM for observability, while @llama_index LiteParse handles the markdown conversion step
As always, it’s fully OSS and self-hostable: http://github.com/AstraBert/pdfitdown-app… Leave a little to PdfItDown as well: http://github.com/AstraBert/PdfItDown…
