Features and specs

What each product offers, as listed by its team.

ConvertDuck 5 features
CloudLinux 5 features
  • User-friendly Interface
    ConvertDuck offers a clean and intuitive interface that makes it easy for users of all levels to navigate and perform file conversions efficiently.
  • Support for Multiple Formats
    The platform supports a wide variety of file formats, allowing users to convert documents, images, and other types of files seamlessly.
  • Fast Conversion Speeds
    ConvertDuck processes conversions quickly, minimizing waiting times and increasing productivity for users who need to handle multiple files.
  • No Registration Required
    Users can convert files without the need to create an account, which speeds up the process and enhances privacy.
  • Cross-Platform Accessibility
    Since ConvertDuck is web-based, users can access it from any internet-connected device, providing flexibility and convenience.

Possible disadvantages

  • Limited Advanced Features
    While suitable for basic conversions, the platform may lack advanced features required by professional users who need more control over the conversion process.
  • Dependence on Internet Connection
    As an online tool, ConvertDuck requires a stable internet connection, which might be a limitation for users in areas with poor connectivity.
  • Potential Security Concerns
    Uploading files to a web-based service can raise security and privacy concerns, especially when dealing with sensitive or confidential data.
  • File Size Limitations
    The platform might impose limits on the size of files that can be uploaded for conversion, which could be restrictive for users with large files.
  • Ads and Upselling
    Free versions of ConvertDuck might include ads or attempt to upsell premium features, which can be distracting or frustrating for users.
  • Enhanced Server Stability
    CloudLinux uses its lightweight virtualization technology (LVE) to isolate each tenant on a shared hosting server, preventing any single user from consuming excessive resources and crashing the server for everyone else. This ensures consistent uptime and performance.
  • Improved Security with HardenedPHP and KernelCare
    CloudLinux offers HardenedPHP, which patches old and unsupported PHP versions against known vulnerabilities, and KernelCare, which provides live kernel patching without requiring server reboots. These features significantly enhance server security posture.
  • Resource Limit Management
    Administrators can set granular resource limits (CPU, memory, I/O, number of processes, etc.) per user account using LVE Manager. This makes it easy to manage shared hosting environments and ensure fair resource distribution among tenants.
  • CageFS File System Virtualization
    CageFS creates a virtualized file system for each user, preventing them from seeing other users on the server, viewing sensitive configuration files, or exploiting server vulnerabilities. This adds an important layer of isolation and security.
  • Wide Compatibility with Hosting Panels
    CloudLinux integrates seamlessly with popular hosting control panels such as cPanel, Plesk, and DirectAdmin, making it straightforward for hosting providers to adopt without overhauling their existing infrastructure or workflows.

Possible disadvantages

  • Additional Licensing Cost
    CloudLinux requires a paid monthly or annual license on top of the base server cost. For smaller hosting providers or individual server owners, this additional expense can add up and may not always be justifiable compared to free alternatives.
  • Limited to CentOS/RHEL-Based Systems
    CloudLinux is built on top of RHEL/CentOS and does not support other Linux distributions like Ubuntu or Debian. This limits its adoption for hosting providers who prefer or already run non-RHEL-based environments.
  • Learning Curve for Configuration
    While CloudLinux provides powerful resource management tools, properly configuring LVE limits, CageFS, PHP Selector, and other features requires a solid understanding of the platform. Misconfiguration can lead to users being unnecessarily restricted or resources being poorly allocated.
  • Potential Performance Overhead
    The additional layers of virtualization, resource monitoring, and file system isolation introduced by CloudLinux can impose a slight performance overhead on the server compared to running a bare, unmodified Linux distribution without these controls.
  • Dependency on CloudLinux Ecosystem
    Adopting CloudLinux means relying on their ecosystem for kernel updates, PHP patches, and security fixes. If the company experiences delays in releasing patches or changes its pricing/licensing model, hosting providers may find themselves locked into a dependency that is difficult to migrate away from.

Questions & Answers

As answered by people managing ConvertDuck and CloudLinux.

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.
