Qompressor

Qompressor is a macOS interface for size-targeted video encoding built on FFmpeg. It supports single-file and batch processing, letting you define an exact output size and automatically computes the appropriate bitrate to match it. Users can select H.264 or H.265, adjust resolution, toggle VideoToolbox hardware acceleration, choose AAC bitrate, and switch between CRF- and size-constrained workflows. Qompressor handles the FFmpeg invocation and parameter calculation, offering a direct way to produce predictable, size-bounded outputs without manually scripting commands.
