  • Batch Management: You can process up to 5 files per batch. If you have a larger collection, simply process them in smaller groups to maintain optimal performance.
  • Privacy First: Because this is a private file converter, you never need to worry about data leaks. Since no files are uploaded, your archives are never stored or tracked by any third party.
  • Browser Compatibility: For the best experience with our free WASM converter, ensure you are using an up-to-date version of Chrome, Firefox, or Edge. These browsers provide the best support for the WebAssembly architecture that powers our platform.
