Images are a massive part of the web these days—whether for e-commerce, portfolios, or social networks. But working with images tends to have trade-offs. Older websites upload your images to a server for conversion, compression, or optimization. It's a privacy issue and a performance bottleneck because each file must be transmitted to a distant server before it can be processed and then downloaded once more.
Filecnv's solution:
With Filecnv image processing is now possible in the browser itself, without server round-trips. That means better speed, enhanced privacy, and a more seamless user experience for free, no sign up required!

The Problem with Traditional Image Processing websites
When a site relies on back-end servers to process images:
- Privacy issues – Your personal or sensitive photos are sent to another's servers..
- Network delays – Big image files take seconds (or minutes) to upload and download.
- Unpredictable on bad connections – On slow or bad networks, processing is infuriating.
For today's users, this is clunky.
Uses Rust + WebAssembly
Rust is a systems programming language known for speed, safety, and memory efficiency. WebAssembly is a low-level, platform-agnostic binary format that executes at near-native speeds within web browsers.
With Filecnv, Rust and WebAssembly enable us to:
- Compile image libraries in Rust into WebAssembly and execute in the browser.
- Process images locally – change formats, compress files, resize photos – files without leaving your device.
- Eliminate uploads and downloads – no waiting for round-trips to a server.
- Ensure privacy – files never leave the user’s computer.
In essence, the browser itself is now the image editor, given a boost by Rust's performance.
Benefits for Users
- Speed – Image conversion and compression occur instantly, without having to wait on network transfers.
- Privacy – Files stay on your device. Nothing is uploaded to external servers.
- Cross-Platform – Operates on any current browser (Chrome, Firefox, Safari, Edge) on any device.
Conclusion
Filecnv with Rust + Web Assembly enable a new generation of fast, secure, and privacy-friendly web apps. Rather than sending personal data to a distant server, we can now process it locally on the user's device.
The future of image processing is local, private, and fueled by Web Assembly!
