Questions & Answers

As answered by people managing ConvertDuck and NexTools.space.

What makes your product unique?

ConvertDuck's answer

ConvertDuck is distinct because it operates 100% locally within the user's browser. Unlike traditional converters that require uploading files to a remote server, ConvertDuck processes everything on the client side using advanced web technologies (WebAssembly). This means your files never leave your device, ensuring absolute privacy and zero exposure to network vulnerabilities.

Why should a person choose your product over its competitors?

ConvertDuck's answer

You should choose ConvertDuck if you prioritize security. Competitors expose your data to multiple risks: network interception during upload, potential server hacks, and unauthorized data retention. ConvertDuck eliminates these attack vectors entirely. By removing the server from the equation, we guarantee that your sensitive files cannot be stolen, leaked, or infected with malware during the conversion process.

How would you describe the primary audience of your product?

ConvertDuck's answer

Our primary audience consists of security-conscious individuals, privacy advocates, and professionals who handle sensitive or confidential documents. This includes developers, journalists, corporate employees, and anyone who understands the risks of sharing personal data with unknown third-party servers and wants a "zero-trust" solution for their file management.

What's the story behind your product?

ConvertDuck's answer

ConvertDuck was born from a fundamental distrust of server-side file processing. We recognized that no matter how much a service promises security, once a file leaves the user's computer, it is vulnerable to hacking, interception, and misuse. We built ConvertDuck to prove that convenience doesn't have to come at the cost of privacy, creating a tool that allows users to "leave no trace" on the internet.

Which are the primary technologies used for building your product?

ConvertDuck's answer

ConvertDuck is built using modern, high-performance web technologies including Astro and SolidJS for a fast and reactive user interface. The core conversion engine relies on WebAssembly (WASM), which allows complex file processing tasks to run directly in the browser with native-like performance, removing the need for backend servers.

Who are some of the biggest customers of your product?

ConvertDuck's answer

As a privacy-focused platform accessible to everyone, our user base is diverse and anonymous by design. We serve individual users worldwide who refuse to compromise on data sovereignty. Rather than targeting specific enterprise giants, we empower every user—from students to security experts—to convert their files without fear of surveillance or data theft.
