Frequently Asked Questions
Which video format is best for sharing?↓
MP4 with H.264 codec is the most universally compatible format. It plays on virtually every device, browser, and social media platform without transcoding.
What is the difference between MP4 and MKV?↓
Both are container formats. MP4 is more widely supported for playback but limited in codec and track options. MKV supports virtually any codec and can hold multiple audio tracks, subtitles, and chapters — ideal for archival.
Does conversion reduce video quality?↓
Converting between lossy formats (like MP4 to AVI) may slightly reduce quality due to re-encoding. Converting to a container-only format change (like MKV to MP4 with the same codec) preserves quality. For best results, avoid converting the same file multiple times.
Is there a file size limit?↓
Yes, there is a per-file upload limit to ensure fast processing times. The limit is displayed when you select a file.
