💡 Tips & Best Practices
- For YouTube uploads, use H.264 + AAC + 1920×1080 + CRF 18 for best results
- For WhatsApp/Telegram sharing, use the Mobile preset to keep file size under 16MB
- Enable Fast Start if you plan to play the video in a web browser or embed it online
- Use Copy Stream codec only if the AVI already uses H.264 — this is the fastest option
- For old DivX/Xvid AVIs, H.264 at CRF 20 usually gives excellent results with 50% size reduction
- Close other browser tabs during large file conversions for better performance
- If conversion fails, try a lower resolution or smaller CRF value (higher number)
🔒 Privacy & Security
- All conversion happens entirely in your browser — your files never leave your device
- No files are uploaded to any server or stored anywhere outside your computer
- Your files are not shared with any third parties
