Faster uploads, smaller files — private, watermark‑free compression
Balanced quality for platforms; good clarity at smaller size.
Smaller file size for mail limits; acceptable clarity for speech.
Higher quality for long‑term storage; preserve original resolution.
Shrink video files for faster sharing, quicker uploads, and lighter storage while keeping them looking sharp. Tune resolution (1080p/720p/480p), CRF, preset, and audio bitrate to reach a target size and quality that fits your use case. Lower resolution and higher CRF reduce size; slower presets squeeze out extra savings. All processing happens privately in your browser (WebAssembly) — files never leave your device. Output is watermark‑free and ready for Instagram, WhatsApp, X/Twitter, YouTube, and email. Perfect for saving mobile data, meeting email limits, and keeping archives lean.
Typical range is 18–28. Lower CRF = better quality but larger files. Social uploads often work well at CRF 23; email attachments around CRF 28; archiving at CRF 20 for higher fidelity.
96k is fine for speech and mail attachments; 128k suits most social content; 192k is better for archiving or music. Keep stereo when needed.
H.265 (HEVC) can produce smaller files at similar quality but encodes slower and may have lower device compatibility. H.264 is faster and widely supported.
Match bitrate to your use case. For speech 96–128k is usually sufficient; for music use 160–192k. Keeping sample rate and channels consistent helps quality.
Slower presets usually compress more efficiently (smaller size) but take longer. Medium is a solid balance; use Slow for archiving and Fast for quick publishing.
Lower resolutions reduce bitrate requirements and file size. 720p is good for social, 480p for email, and keeping original is best for archiving.
