Why use
Your files never leave your device. No internet connection is required — no servers, no tracking, no data collection of any kind.
Uses native hardware acceleration (MediaCodec on Android, VideoToolbox on iOS/macOS) for blazing-fast compression.
KIVO never modifies or deletes your source file. It only creates a compressed copy — your original stays exactly as it was.
No ads, no paid plans, no usage limits. KIVO is and always will be free.
The story behind
KIVO was born from a real need: attaching files in emails or Jira without depending on an online service that would store your file on some unknown server.
The core idea is simple — your files are yours. Whether it's personal photos or company documents, sensitive data should never have to pass through a third-party server just to get smaller.
Built with Flutter, KIVO runs natively on Android, iOS, macOS, Windows, and Linux from a single codebase. Compression is done with well-established open‑source libraries — FFmpeg, flutter_image_compress, and iText — all operating entirely on your device.
The original file is never modified. KIVO reads the source file, creates a compressed copy in the location you choose, and nothing else.
