Frequently Asked Questions - Video Conversion

What video formats are supported?

MP4, MOV (QuickTime), AVI, MKV (Matroska), WebM, WMV, FLV, M4V, MTS/AVCHD, 3GP, and more. Both input and output support all listed formats.

Is video quality preserved during conversion?

Yes. For container-switching conversions (e.g., MKV to MP4) where the video codec is already compatible, we use remuxing - direct stream copy with original video preserved. For codec-changing conversions, we use high-quality settings to minimize loss.

Are embedded subtitles preserved?

Yes. Embedded SRT, ASS, and VTT subtitle tracks are detected and preserved in formats that support them (MKV, MP4 with SRT passthrough).

Is there a file size limit?

A typical 1-hour 1080p MP4 is usually 1–4 GB depending on bitrate. The maximum file size depends on your plan.

Is there a watermark on converted videos?

No. Converted videos are completely clean - no overlays, watermarks, or branding.

Is my video kept private?

Files are encrypted in transit and at rest. How long they are kept depends on your plan.
