About BastosConvert
Free file tools that work in your browser. No signup, no upsell, no dark patterns.
Why BastosConvert
Most file-conversion sites bury the actual tool under newsletter pop-ups, paywalls, and shady ad networks. BastosConvert exists to flip that: every tool is free, every tool runs without an account, and every tool does exactly one job. The promise is boring on purpose — open the page, drop a file, get the result.
How it's built
The conversion pipeline is written in Rust. PDFs go through lopdf, media through ffmpeg, images through native crates. Each request hits an Actix worker, and every successful conversion is keyed by a content hash so repeat work is served from cache in milliseconds. The front-end is generated from a Bastos DSL into a Next.js 16 app — same primitives as every other Bastos showcase.
Privacy posture
Files are processed in memory or on a short-lived temp disk and discarded as soon as the response is sent — at most within a few minutes. Nothing is stored long-term, nothing is used for training, and no file content ever leaves the Bastos infrastructure. The full policy lives on the privacy page.
Who's behind it
BastosConvert is a solo project, built and maintained by one developer as a showcase of the bastos-cms platform. Source code, issues, and roadmap are tracked publicly.
