How to Pixelate a Video Online (Free, No Upload)
November 3, 2026
Short answerOpen Blur The Video in your browser, drag a box over the area, switch its effect to Pixelate, raise the strength until the area is unrecognisable, set the start and end time, and export.
Pixelation (the mosaic effect) replaces an area with large coloured blocks. It is the classic TV look for hiding faces and plates, and it is clearly deliberate, so viewers don't mistake it for a focus problem. Many online pixelators upload your clip to a server first. This one doesn't.
Typical uses: hiding bystanders in vlogs, covering number plates in dashcam clips, masking a monitor in an office video, or anonymising a participant in an interview recording.
Step by step
- Open the online pixelate editor and load your video. It stays on your device.
- Drag on the video to draw a box over the face, plate or screen.
- In the panel on the right, set Effect to Pixelate.
- Move the Strength slider up. Higher strength means bigger blocks and less recognisable detail.
- Set the box's timing with Start here and End here.
- Add more boxes as needed (Cmd/Ctrl + D duplicates the selected one with the same settings).
- Export as MP4 if your browser offers it, otherwise WebM.
Choosing the right strength
- Faces: you want fewer than about five or six blocks across the face. If you can still recognise someone you know, go higher.
- License plates and short text: use big blocks or switch to Solid. Small mosaics over short text can sometimes be guessed.
- Whole screens: a medium strength is usually enough to make text unreadable while showing that a screen is there.
- Small boxes need relatively stronger settings, because the block size is fixed in pixels, not relative to the box.
- Check on the export, not just the preview. Watch the exported file at full screen, the way your viewers will, and make sure nothing is recognisable.
- Add margin. Extend the box a little beyond the edges of the face or plate so outlines and edges of characters are covered too.
Pixelate, blur or solid?
Pixelate looks intentional and holds up well. Blur looks softer and fits vlogs or product videos better. Solid is the only option that is fully irreversible and the right choice for passwords or ID numbers. You can mix them in the same video, since each box has its own effect. For the security side, read can a blurred video be unblurred.
Limitations
The pixelate box doesn't track motion. For moving subjects, use a bigger box or several boxes one after another. Export runs in real time, so a two-minute clip takes about two minutes. Free exports include a small watermark; removing it costs $0.99 for one video or $19.99 for lifetime access, with no subscription.
FAQ
Is pixelating a video online free? Yes, with a small watermark on the export. Removing the watermark is $0.99 per video or $19.99 once for unlimited videos.
Can I pixelate only part of the video? Yes. Every box covers only its own area and only between its start and end time.
Is pixelation reversible? Not at a strong setting. Coarse pixelation removes the detail. Fine pixelation over short text can sometimes be guessed, so use big blocks or a solid box for text.
Does it work on a phone? It can work in recent mobile browsers, but the editor is designed for desktop and is more comfortable on a larger screen.
