On October 24, 2026, a 10-second 1280×720 MOV (H.264 video, AAC sound) went through this page’s button in each browser, and what came out was read back with ffprobe.

The test file carried a location tag; no converted copy kept it.

iPhones record HEVC video by default. A MOV like that converted in Google Chrome 155 and WebKit 27.2 (Safari’s engine).

When to turn MOV into WebM

Web pages and browser-based tools often take WebM because it is an open format every major browser plays. A MOV straight from an iPhone or a Mac screen recording is the usual starting point.

Transparency is the catch people search for: a MOV with an alpha channel, as motion graphics often have, doesn’t keep it here. The WebM comes out with a solid background, so use a desktop encoder for transparent overlays.

MOV and WebM, in short

MOV
Apple’s QuickTime format. iPhones and Macs save videos and screen recordings as MOV, and recent iPhones put HEVC video inside, which some computers and apps can’t play.
WebM
Google’s open web format, with VP8, VP9 or AV1 video and Opus or Vorbis sound. Browser screen recorders and many downloaded web videos come as WebM.

How to convert

  1. Open the MOV

    Press the button and drop the file, or pick it from your files. It opens in this browser tab: nothing is uploaded, so there is no upload limit to hit.

  2. WebM is already chosen

    The save window opens set to it. Change the file name or the quality if you like.

  3. Save

    The new file is written on your device and downloaded. Several files? Drop them together and they are converted one after another.

What changes, what stays

Picture and length
Nothing is cut or reframed: the video keeps its own picture size and runs from start to end.
Sound
The first sound track, at its own level, in stereo at most.
Quality
Small, Balanced or High; Balanced is chosen to begin with.
Details about you
The file is written from scratch, so none of the original’s metadata comes along: no location, no camera or phone model.

Questions

Does the WebM keep my MOV’s transparency?

No. Shycut writes WebM without an alpha channel, so transparent areas come out solid.

Can I make a WebM from an iPhone video?

Yes, where the browser decodes the iPhone’s HEVC video: the note under the test table says which tested browsers did.

Is the WebM lighter than the MOV?

At the same quality setting it usually is, VP9 being the more efficient codec. Choose Small for an even lighter file.

Your video stays with you.

Open Shycut, drop the video in and export. Free, with no account, and your video never leaves your device.
