This is the page for the video that will not play: an MKV a TV refuses, a WebM a editor will not import, a MOV too large to send. Convert it to a standard MP4 — H.264 picture, AAC sound — that every phone, TV, browser and editor opens, or pick any of MP4, WEBM, MOV, MKV, AVI, FLV, WMV, 3GP, M4V and TS as the output. When the source codecs are already MP4-compatible the picture is preserved faithfully; best settings are preselected. Free, no sign-up, no service-added watermark, and your file is deleted the moment your download finishes.

The Video Converter on SnagYouTube works on the file itself: MP4 · WEBM · MOV · MKV · AVI · FLV · WMV · 3GP · M4V · TS. Bring the video in once — no relay of re-uploads to single-purpose sites — finish the job here, and download the result; the working copy is deleted the moment your download finishes.

About this conversion

The facts, answer-first: input is one video file in any of MP4, WEBM, MOV, MKV, AVI, FLV, WMV, 3GP, M4V or TS. Output is the format you pick, with MP4 (H.264 + AAC) as the compatibility default. Conversion is a decode-and-re-encode at high-quality settings unless the source codecs already match the target, in which case quality is preserved exactly. There is no daily cap, no account and no watermark added. Your file is processed in a one-off temporary folder and deleted the moment your download finishes — nothing is kept, catalogued or shared.

How to use the video converter

  1. Upload your file — drag & drop it or tap to browse.
  2. Set any options, then hit the button.
  3. Watch the short ad — your finished file downloads instantly.

FAQ

Why does my MKV play on my computer but not on my TV or phone?

Because MKV is a container, not a promise: inside it can sit video and audio codecs your TV or phone never licensed — HEVC, AV1, DTS and others. Players on a computer fetch codecs freely; TVs and phones play only their built-in set. Converting to MP4 with H.264 video and AAC audio puts the same picture and sound into the combination every screen already speaks.

Will converting MKV to MP4 lose quality?

It depends which of the two jobs yours is. If the MKV already holds H.264 video and AAC audio, only the wrapper changes and the picture is preserved. If the codecs themselves must change — say HEVC to H.264 — the video is re-encoded once at high-quality settings: a small, usually invisible cost, paid once. Re-encoding back and forth repeatedly is what compounds loss, so keep the MKV as your master.

What happens to subtitles and extra audio tracks in an MKV?

MKV files often carry several: subtitle tracks in many languages, a commentary track, a second dub. A standard MP4 carries one main audio track cleanly and subtitles only in forms many players ignore, so before converting a film with tracks you care about, read the MKV guide on this site — it walks through which track to keep and when burning subtitles in is the honest answer.

Which format should I convert to for WhatsApp, email or an upload form?

MP4, at a smaller size rather than a different format: those limits are byte limits, not format opinions. The Compress Video to Size tool hits an exact target — under 16 MB for WhatsApp, under 25 MB for most email — and is the right second step when the converted MP4 is still too large to send.

Is this really free?

Yes — completely. A short ad before processing keeps every tool free; no account, subscription or credits are ever required.

What happens to my file?

It is processed in a temporary folder and deleted the moment your download finishes. We never store, view or share uploads.

Do I need to install anything?

No. Everything runs in your browser session against our servers — any phone, tablet or computer works.
