Tips & Best Practices
- Convert on your device: Converting on your device keeps your file private. Use Upload to Toolsvana only if the conversion on your device fails.
- Use High quality: The "High" quality setting is recommended for most conversions, providing excellent quality with reasonable file sizes.
- Check the video codec: H.264, H.265 and AV1 video converts fast with no quality loss; other video takes longer because it is converted to H.264.
- If conversion fails: Files up to 95 MB can also be converted with Upload to Toolsvana.
- Monitor conversion progress: The progress bar and processing stats help you track the conversion. If it appears stuck, try refreshing and using Upload to Toolsvana (files up to 95 MB).
- Verify the output: Always compare the before and after file sizes displayed in the conversion summary to ensure the result meets your expectations.
