About Wandly
Wandly is a lightweight, zero-maintenance web tool built to convert popular office document files (Word, Excel, PowerPoint, Images) into high-quality PDFs. By using Cloudflare Pages, Workers, R2, and Hugging Face Docker, our architecture operates on an ultra-low budget, passing the savings to you in the form of a free tool with no watermarks or registration required.
How We Run at $0 Cost
Traditional conversion sites run expensive monolithic virtual machines to host heavy libraries like LibreOffice. We solved this by splitting our application into a high-performance serverless network:
Cloudflare Pages
Delivers the statically built Astro frontend instantly from edge servers globally with zero bandwidth costs.
Cloudflare Workers
Processes secure API routing, checks uploads, and streams files directly to our storage in milliseconds.
Cloudflare R2
Provides 10GB of secure storage with zero egress fees, storing files temporarily and deleting them within 1 hour.
Hugging Face Spaces
Runs an isolated Docker CPU container that wakes up on demand to process heavy office document conversions inside clean sandbox folders.
Core Values
- Private Storage: Files are stored temporarily in private storage to process the conversion. We do not inspect file content.
- Auto-Deletion after 1 Hour: All inputs and outputs expire and are deleted after 1 hour. We do not store files permanently.
- Accessibility: Pure CSS, zero heavy JS frameworks, highly accessible layout and fast page loads.
