How do I convert a MOV to MP4 on a Mac for free?

Use Crisp. Drop your MOV in, pick the Convert lane (or type "convert to mp4"), choose MP4, and press it. Crisp changes the container entirely on your Mac, with no account, no upload and no watermark.

Does converting lose quality?

Usually not. Most MOV files already contain H.264 or HEVC video, which Crisp copies straight into the MP4 — a lossless remux, so there's no quality loss and it's fast. It only re-encodes if the source codec can't live in the target container.

Can it convert AVI, MKV or WebM too?

Yes — drop in an AVI, MKV or WebM and convert it to MP4 or MOV. If its video codec fits the target, it's copied losslessly; otherwise Crisp re-encodes it for you.

Is my video uploaded to a server?

No. Crisp converts entirely on your Mac, so there's no upload, no queue, no size cap, and your footage never leaves the device — unlike the "convert video online" sites.

What's the difference between Convert and Compress?

Convert changes the container/format (MOV → MP4) and keeps the quality; Compress shrinks the file size. Use Convert when a file won't upload or open; use Compress when it's too big.

How to convert MOV to MP4 on a Mac

Your Mac records in .mov, but the site, app, or person you're sending it to wants .mp4 — and half the "converters" online want to upload your footage first. Here's how to convert MOV to MP4 on a Mac in one tap, 100% offline, usually losslessly: no account, no upload, no watermark.

Updated July 2026 · step-by-step

The fastest way: just ask

Crisp has a plain-English box ("Or just tell Crisp what to do…"). Drop your video in and type it:

convert to mp4 — the usual one
make it an mp4 — same thing
convert it to mov — the other way
change the format to mp4 — plain English

Crisp reads the request, switches to the Convert lane with the format you named, and you just press the button.

Step by step: the Convert lane

Open Crisp and drop in your video

Get the free Crisp app for Mac and drag your MOV onto the window. Nothing is uploaded — the whole job runs on your Mac.
Pick the Convert lane

Choose Convert in the task row.
Choose MP4

Pick MP4 (or MOV). When the video already fits (H.264/HEVC — which most MOVs are), Crisp copies it losslessly — no re-encode, no quality loss, and it's fast.
Save

The .mp4 lands beside your original — watermark-free, and your MOV is untouched.

Lossless when it can be — no needless re-encode

A MOV and an MP4 are just different wrappers around the same video. Most MOV files hold H.264 or HEVC, which live happily in an MP4 — so Crisp does a stream copy: it re-wraps the exact same video (no re-encode, no quality loss, seconds not minutes). It only falls back to re-encoding if the source codec genuinely can't live in the target container. Want a smaller file too? That's Compress, a different job.

Convert vs Compress

Convert — change the format/container (MOV → MP4), keep the quality. That's this guide.
Compress — shrink the file size (for email/upload), keep the resolution. See compress a video.

Crisp vs online converters vs Handbrake

	Crisp	Online converters	Handbrake
One-tap MOV → MP4	Yes	Yes	Settings-heavy
Lossless (copies the video)	Yes (when codec fits)	Re-encodes	Always re-encodes
Plain-English request	Yes	No	No
100% offline, nothing uploaded	Yes	Uploads your clip	Yes
Price	Free during beta	Free + size caps	Free

Online converters upload your footage and always re-encode (slower, quality loss); Handbrake is powerful but re-encodes everything and buries you in settings. Crisp re-wraps losslessly in one tap and stays local.

Why offline matters

Your footage stays yours. The "convert MOV to MP4 online" sites upload your clip first. Crisp does it on your Mac.
No size cap, no queue. Convert a 4K clip of any length, right now.
Fast & lossless. A stream copy re-wraps in seconds with zero quality loss.

Convert your video — offline

Free to try on your Mac. One tap to turn a MOV into an MP4 — no account, no upload, nothing leaves your device.
