Frequently asked questions
Is this MOV to WEBM converter free?+
Yes, with no watermark and no account. The engine runs locally in your browser, so there's no server queue limiting usage.
Is my video uploaded to a server?+
No. Orbfile uses your browser's own built-in media codecs (via the WebCodecs API and Mediabunny), so encoding happens entirely on your device.
How long will it take?+
It depends on your device and the video's length and resolution — expect roughly real-time to a few times real-time for typical clips.
Is there a maximum file size?+
There's no fixed upload limit — since everything runs on your device, the practical limit is your browser's available memory, which handles typical clips and even fairly long recordings without issue.
How do I convert MOV to WEBM?+
Drop your MOV file into the box above — Orbfile re-encodes it to WEBM using your browser's own codecs and gives you a download link when it's done.
About MOV and WEBM
What is MOV?
MOV is Apple's QuickTime container format — it's what iPhones record video into by default.
Full MOV format guide →What is WEBM?
WEBM is an open, royalty-free video format built for the web, typically using the VP9 codec for strong compression at small sizes.
Full WEBM format guide →The short version: WEBM gives you excellent compression for web delivery, which helps once you run into MOV's biggest limitation: some non-Apple platforms and older editors handle it inconsistently. It's a natural move when your video is headed toward embedding video on websites.

Download the result
Your browser processes everything locally and hands you a download link the moment it's done — nothing was ever sent to a server.
Is it private?
Everything happens locally, inside this browser tab. Your video is read from disk, processed with WebAssembly running on your own device, and handed back to you as a download — it's never transmitted anywhere, so there's nothing to intercept and nothing stored on a server.

About MOV files+
MOV is Apple's QuickTime container format — it's what iPhones record video into by default.
MOV was built by Apple as the native container for QuickTime back in the early 1990s, well before MP4 existed — in fact, the ISO base media format that MP4 is built on borrows heavily from QuickTime's original design. Today it's mainly notable as the format iPhones record video into and the format Final Cut Pro and other Apple editing tools favor, including support for high-end codecs like ProRes that MP4 doesn't typically carry.
How to open a MOV file
Opens readily in QuickTime Player, Most modern browsers and media players. For real editing, use Final Cut Pro, Adobe Premiere Pro, iMovie.
Good for
- native to Apple's camera and editing apps
- supports high-quality codecs like ProRes
Watch out for
- some non-Apple platforms and older editors handle it inconsistently
About WEBM files+
WEBM is an open, royalty-free video format built for the web, typically using the VP9 codec for strong compression at small sizes.
Google introduced WebM alongside WebP as a royalty-free alternative built specifically for the browser, most commonly pairing the VP9 (or newer AV1) video codec with Opus audio in a lightweight container. That combination tends to compress noticeably better than the more universally-compatible H.264/MP4 pairing, which is why WebM shows up heavily in web video embeds and platforms like YouTube use it internally, even when they serve MP4 for broader device compatibility.
How to open a WEBM file
Opens readily in Chrome, Firefox, Edge (native), VLC Media Player. For real editing, use DaVinci Resolve, Adobe Premiere Pro (with an extension).
Good for
- excellent compression for web delivery
- royalty-free, no licensing overhead
Watch out for
- less commonly used than MP4 outside web contexts
