Conversion Rate Calculator divides conversions by total visitors and displays the rate as a percentage with configurable decimal precision. Everything runs locally in your browser — nothing is uploaded.
Three methods: CRF (Constant Rate Factor) for quality-based compression, resolution scaling to reduce dimensions, and bitrate control for predictable file sizes. Combine methods for maximum reduction.
CRF (Constant Rate Factor) controls quality. Lower CRF = higher quality/larger file. Typical values: 18 (high quality), 23 (default/good balance), 28 (smaller file). 18-23 is recommended for most use cases.
MP4, MOV, WebM, MKV, and AVI inputs are supported. Output is typically MP4 or WebM. The tool uses FFmpeg for encoding.
Yes. The tool includes a quality preview feature so you can check the visual result at your chosen CRF/bitrate settings before committing to the full compression.
No. All compression runs locally in your browser using FFmpeg WASM. Your video never leaves your device.
