💡 Helpful Tips

  • Preset Option: Preset selection only slightly affects quality and file size, but may greatly increase the processing time.
  • CRF Mode: Best for maintaining consistent quality across your entire video.
  • Bitrate Mode: Best when you need predictable file sizes.
  • Max Size Mode: Automatically calculates the best bitrate for your target file size.
  • Audio Quality: Higher audio bitrates are only noticeable for music or high-quality audio content.

⚠️ Browser Limitations

  • Threading: Limited to maximum 4 CPU threads due to browser WebAssembly restrictions
  • Processing Speed: Slower than desktop software due to browser environment limitations
  • Format Support: Limited to MP4 output due to memory constraints in browsers
  • Memory Usage: Large videos may cause browser memory issues
  • Better Codecs Available: For superior quality and compression, consider MP4 with AV1 codec or WebM with VP9/AV1 codecs. However, these are not supported in browsers due to memory limitations.
🔒 But Remember: These limitations are the price of complete privacy! Your videos never leave your device, ensuring 100% data security.
