VidShrink is a video processing tool designed to reduce video file sizes by targeting an exact megabyte value rather than relying on trial and error. The program accepts a source video, lets the operator select a desired output size, and then determines the codec, quality level, resolution and frame rate required to land just beneath that limit. Additional modules provide playback, screen recording, editing and format conversion within the same application window.
VidShrink was created by Mustafa Özel. The program is written in Python and has been developed since the early 2020s as a practical answer to the recurring problem of video files exceeding size limits imposed by messaging platforms, email gateways and upload forms. The development focus has been on replacing guesswork with measured encoding decisions, which led to the inclusion of encoder probing on the local machine and VMAF-NEG quality scoring. The application requires ffmpeg to be installed, and the home page provides a script for that purpose. The project documentation is stored in docs/kullanim.md, and share target ceilings are defined in paylasim-hedefleri.json, allowing the list of supported destinations to be extended without altering the program logic.
