FAQ

  • Why can a compressed file become larger? High-quality output, format conversion, keeping resolution, or keeping metadata may increase file size. Try lower quality, smaller resolution, or a more space-saving format.
  • Does the App upload my files? No by default. Media processing is performed locally. Files are sent to other services only when you choose to share them through the system share sheet.
  • Why do some features require Pro? Pro formats, advanced controls, audio tools, video-to-audio, and batch workflows require more local processing capability and are provided as Pro features.
  • What if a task is interrupted? If the system closes the App or a task is unfinished when you leave, the task may fail. Open task details and try again.
  • How can I free storage? Use Settings - Clear Cache to delete temporary files and thumbnails. Files exported to Photos, Files, or other locations must be managed there.
