Frequently Asked Questions
MKV is great for desktop playback but most phones, browsers, and social media platforms cannot play it. MP4 works everywhere.
Soft subtitle tracks (SRT/ASS embedded in the MKV container) are not transferred. Hardcoded (burned-in) subtitles are preserved since they are part of the video image.
The primary audio track is converted. Secondary audio tracks (commentary, alternate languages) are not included in the MP4 output.
MiOffice re-encodes to H.264. On "high" quality the difference is visually imperceptible. File size may actually decrease due to more efficient H.264 compression.
Yes. Upload up to 10 MKV files and convert them all to MP4 simultaneously.
500MB per file. Everything processes locally in your browser — no server uploads, no waiting in a queue.
A 300MB MKV typically takes 3-7 minutes in the browser. Processing speed depends on your device hardware.
Yes, resolution is preserved. A 4K MKV converts to a 4K MP4. Just make sure the file is under 500MB.
No. By default, FFmpeg runs via WebAssembly in your browser. On some devices, processing may use our secure server.
Chapter markers are not transferred to the MP4 output. The video plays as a continuous stream.
