Hard to reverse
Averaging each block throws the detail away, so the covered region cannot be reconstructed from the export.
Pixelated blur
Add mosaic blur to videos and images
You do not need a desktop timeline editor for common pixelated blur tasks. Step-by-step face pixelation is available in your browser — MP4, MOV, M4V, AVI and MKV supported, with preview and HD export.

Why mosaic
When soft blur isn't enough
Gaussian blur looks natural but keeps some structure. Mosaic and pixelation destroy it — which is what a compliance deliverable usually needs.
Block size you choose
Fine pixelation keeps the shape readable; chunky mosaic removes it entirely. Both are one slider away.
Broad format support
MP4, MOV, M4V, AVI and MKV in, with preview and HD export out.
Step-by-step face pixelation
Detected faces can be pixelated one by one, so you decide exactly who is covered.
Images too
The same mosaic runs on stills — useful for screenshots, documents and listing photos.
Rendered into the file
The mosaic is baked into the exported pixels rather than laid over them, so there is no overlay to remove.
How to pixelate a video
No timeline editor required
Common pixelation jobs shouldn't need a desktop suite.
Upload the file
MP4, MOV, M4V, AVI or MKV — straight into the browser.
Choose what to pixelate
Detected faces and plates, named objects, or a box you draw yourself.
Preview, then HD export
Check the block size on the live preview and download in HD.

Pixelate a still in the same tool
Screenshots with account numbers, documents with names, listing photos with a visible house number — same mosaic, single file.
- Screenshots where a chat name or balance shouldn't ship.
- Documents photographed for an upload form.
- Group photos where only some faces should be covered.
- Listing photos with plates and house numbers in frame.

FAQ
Common questions
Do I need a desktop editor to pixelate a video?
No. You do not need a desktop timeline editor for common pixelated blur tasks — step-by-step face pixelation is available in your browser.
Which video formats can I upload?
MP4, MOV, M4V, AVI and MKV are supported, with preview and HD export.
Is mosaic safer than blur?
For anonymisation, yes. Mosaic and pixelation discard the detail inside each block, while a light gaussian blur can leave recoverable structure.
Can I pixelate only one face in a group?
Yes. Each detected face is listed separately, so you pick exactly which ones get covered.
Does the export lose quality?
Only the pixelated regions change. Everything else is re-encoded at HD quality.
