Generation loss — quality may degrade
MOV uses lossy compression, and so does WEBM. Converting means decoding and re-encoding — each cycle can permanently degrade quality. Convert from the original source file whenever possible.
Some metadata may not survive
Your MOV file may contain QuickTime atoms, chapter markers metadata. WEBM has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
Default format on iPhone
Your device saves files in MOV by default (iPhone, iPad, Mac cameras). Most people convert because the files won't open on other devices — WEBM is universally supported and will work everywhere.
What compression artifacts to expect
WEBM lossy compression can produce blockiness (VP8), blurring (VP9/AV1). At the high quality settings CocoConvert uses by default, these are usually invisible to the eye. Lower quality settings trade visual fidelity for smaller file sizes.

What Happens When You Convert MOV to WEBM
Your MOV video is transcoded — video and audio streams are decoded and re-encoded into the WEBM container. This is a lossy process that takes time proportional to the video duration.
Your MOV file is demuxed — video, audio, and subtitle streams are separated
The video stream is decoded frame-by-frame, then re-encoded with WEBM-compatible codecs (typically H.264 for MP4)
The audio stream is decoded and re-encoded (or copied if the codec is compatible)
Subtitle and chapter data is preserved where the target supports it
Streams are muxed into the WEBM container and the file is saved
