How to add a watermark to a video on a Mac
Putting your logo on a clip — for a client deliverable, a course, or just to keep your brand on a reel — shouldn't mean uploading your footage to a website that stamps its own watermark on top. Here's how to add a watermark to a video on a Mac in seconds, 100% offline: pick a corner and a size, and Crisp burns your logo in on-device with the audio kept and no watermark of its own.
The fastest way: just ask
Crisp has a plain-English box ("Or just tell Crisp what to do…"). Drop your video in and type what you want:
- add my logo — opens the Watermark lane, top-right by default
- add a watermark — same thing, in words
- watermark this — ready for you to pick the logo
- put my logo in the corner — corner placement
Crisp reads the request, switches to the Watermark lane and sets a sensible corner — you just choose your logo image and press the button.
The manual way: the Watermark lane
-
Open Crisp and drop in your video
Get the free Crisp app for Mac and drag your clip onto the window. Nothing is uploaded — the whole job runs on your Mac.
-
Pick the Watermark lane
Choose Watermark (the 🏷️ button) in the task row.
-
Choose your logo image
Click Choose an image… and pick your logo. A PNG with transparency looks best, so only the mark shows and there's no box around it.
-
Set the position and size
Pick a position — any of the four corners, top or bottom centre, or dead centre — and drag the size slider (5–40% of the video width; 18% is a good starting point). The logo is scaled to that size on every clip regardless of the file's own resolution, so a 200 px logo and a 2000 px logo land identically.
-
Press Watermark
Crisp burns the logo in on-device with hardware encoding, keeps the audio untouched, and saves the result beside your original — watermark-free. Staged several clips? It watermarks each one in the same batch.
The same size on every clip — and never off the edge
Crisp scales your logo to the size you choose as a share of the video width, so it looks consistent whether your logo file is tiny or huge, and whether the clip is 1080p or 4K. Placement is computed from the real, rotation-aware frame — so a portrait clip shot on a phone can't end up with a logo wider than the picture — and the logo's transparency is respected, so you get the mark and nothing else.
Logo watermark vs text watermark
Crisp has two ways to stamp a video, and they're deliberately different:
- Watermark places an image — your logo PNG. Use it for a brand mark or badge in a corner.
- Captions burns in styled text you can position and time. Use it for a name, handle, or © line when you don't have a logo image.
Rule of thumb: a picture → Watermark; words → Captions.
Crisp vs iMovie vs CapCut vs online watermark tools
| Crisp | iMovie | CapCut | Online watermarkers | |
|---|---|---|---|---|
| Add a logo watermark | Yes — one lane | Picture-in-picture hack | Yes | Yes |
| Plain-English request | Yes | No | No | No |
| Transparent PNG respected | Yes | Yes | Yes | Varies |
| Keeps the audio | Yes | Yes | Yes | Varies |
| Adds NO watermark of its own | Yes | Yes | Often on free tier | Usually |
| 100% offline, nothing uploaded | Yes | Yes | Cloud features | Uploads your clip |
| Price | Free during beta | Free | Free + upsell | Free + upsell |
The irony of most "add watermark to video online" sites is that the free tier stamps their logo onto your export. Crisp adds only your mark, on-device.
Why offline matters for watermarking
- Your footage stays yours. The web tools upload your clip first. Crisp watermarks it entirely on your Mac — nothing leaves the device.
- No queue, no size cap. Cloud watermarkers throttle by file size and make you wait; Crisp works on the whole file locally.
- Only your mark. No surprise "made with…" badge added to your export.
- The audio is done right. A watermark changes only the picture; the sound is carried through in sync.

FAQ
How do I add a watermark to a video on a Mac for free?
Use Crisp: drop your clip in, pick the Watermark lane (or type "add my logo"), choose your logo image, set a corner and size, and press Watermark. It burns the logo in and keeps the audio, entirely on your Mac, with no account, no upload and no watermark of its own.
Can I choose where the watermark goes?
Yes — any of the four corners, top or bottom centre, or dead centre, at 5–40% of the video width. Placement uses the real rotation-aware frame, so a portrait phone clip never gets a logo wider than the picture.
Will the logo keep its transparency?
Yes. Crisp respects a PNG's alpha channel, so only the mark is drawn — no opaque box behind it. Export your logo as a transparent PNG for the cleanest look.
Can I add a text watermark instead of a logo?
For text — a name, handle, or © line — use the Captions lane, which burns in styled text you can place and time. The Watermark lane is for a logo image.
Does watermarking re-compress the video?
It re-encodes the picture, but Crisp hardware-encodes at high quality on Apple Silicon and writes the file locally and atomically, so the loss is negligible and you can check the result immediately.
