01About the conversion

Why convert MOV to WebM?

MOV is Apple's QuickTime container — what your iPhone, Mac screen recorder and Final Cut produce. It often holds large H.264 or ProRes tracks that are perfect on Apple hardware but oversized for a fast-loading web page.

WebM is the web's lightweight alternative: an open, royalty-free format built around the VP9 codec, which packs video smaller than H.264 at the same quality. For modern sites targeting Chrome, Firefox, Edge and Android, WebM means quicker loads and lower bandwidth.

Converting MOV to WebM re-encodes the QuickTime stream to VP9 inside the WebM container. TinyVid trims the size hard while keeping the picture clean, and generates embed code with a fallback source, so browsers that prefer MP4 still get a file they can play.

02Step by step

How to convert MOV to WebM

  1. Drop your .mov file above or browse from disk — up to 200 MB free, no sign-up.
  2. The output is preset to VP9 WebM; pick a quality preset such as Standard player or Max compression.
  3. Optional: fine-tune quality and resolution in Advanced settings.
  4. Press Convert and TinyVid encodes the MOV to a VP9 WebM.
  5. Copy the embed code — with an automatic fallback — and paste it into your page.
03FAQ
01How do I convert MOV to WebM for free?
Upload the .mov above and press Convert — files up to 200 MB become WebM for free with no account; up to 4 GB is a one-time payment by size.
02Is WebM smaller than MOV or MP4?
Usually, yes. VP9 in WebM is more efficient than the H.264 or ProRes typically found in MOV, so you get a smaller file at similar quality — ideal for fast pages.
03Which browsers play WebM?
Chrome, Firefox, Edge and Android play VP9 WebM natively. For older Safari/iOS, TinyVid's embed code includes a fallback source so nobody sees a blank player.
04Should I choose WebM or MP4 for my site?
Pick WebM for the smallest files on modern browsers, MP4 for the broadest compatibility. Serving WebM with an MP4 fallback gives you both.
05Does converting MOV to WebM lose quality?
Re-encoding is lossy, but VP9 preserves detail well at small sizes. Raise the Quality slider in Advanced settings if you want to keep more.
06Do I need an app to convert MOV to WebM?
No — it runs online, with no software to install and no login for free or one-time conversions.
