[ ![The pixelate.video home page with the upload card "Drop a video to pixelate or blur", its green Select video button and the supported formats MP4, MOV, WebM and MKV](https://pixelate.video/guides/index/select-video.webp) (enlarge image) ](https://pixelate.video/guides/index/select-video.webp) Click **Select video**, or drag the file onto the upload card. 1. Select video 2. ### Choose what to hide Pixelate or blur the whole video, find faces automatically, or drag on the video to draw boxes over faces, number plates, or screens. Set when each one starts and ends, and use Track movement automatically (or Follow movement by hand) for anything that moves. [ ![The editor with Faces chosen under What do you want to hide?: three friends with a pixelated oval over each face, the side panel listing Faces 7 as a grid of face pictures with Add a face below it, and Face 7, drawn by hand around the man at the right edge, selected with its own settings; the timeline under the video shows one bar per face](https://pixelate.video/guides/index/choose-areas.webp) (enlarge image) ](https://pixelate.video/guides/index/choose-areas.webp) Choose **Faces** and each face gets a pixelated oval that follows the person. Missed one? Pause on it and drag around it on the video (here **Face 7**): it is added to **Faces** and followed for you. 1. Faces 2. An oval follows each face 3. Faces: one picture per face 4. Add a face 5. One bar per face on the timeline 3. ### Download the result Select Export video, then Download video. It is rendered in your browser as MP4 or WebM, with the sound kept (or removed if you prefer).

The guides above cover faces, plates, iPhone and more. ### How do I pixelate a video online? Open your video above and choose The whole video, Faces, or Part of the video. Faces are found and covered for you; for part of the video, drag on it to draw a box. Pick Pixelate, Blur, or Black box under Look, then select Export video to download it. ### Does my video upload anywhere? No. Pixelation and face finding run entirely in your browser using WebCodecs, the open-source mediabunny library, and an on-device face detector. Your file never leaves your device. ### Is it free? Is there a watermark or a length limit? It is free, with no watermark, no signup, and no fixed length or file size limit. Browser memory and device speed set the practical ceiling. ### Can I pixelate or blur a photo instead of a video? Yes. Drop a JPEG, PNG, WebP or iPhone HEIC photo into the same editor. You get the same Faces, Part of the photo and The whole photo choices, then Export photo saves a full-size JPEG, PNG or WebP with no location or camera details in it. Separate photo guides cover faces, censor bars and number plates. ### Can it find and pixelate faces automatically? Yes. Choose Faces and the face finder starts on its own. Each face it finds becomes an oval that follows the person through the video. Very small, distant, or turned-away faces can be missed, so scrub through and add an area for any it skipped. ### How do I pixelate a moving face or object? Draw an area over it, then select Track movement automatically: the area follows the object (a number plate, logo, screen, or face) through the video, on your device. If it loses track, go to that moment, move the area back onto it, and track again. You can also place it yourself with Follow movement by hand, and faces found automatically follow the person already. ### Can I pixelate several people or things at once? Yes. Add as many areas as you need with Add box, Add censor bar or the brush, or by dragging on the video. Each one can have its own shape, start and end time, and its own look under Look for this area. ### Can I pixelate only part of the video, like a few seconds? Yes. Select an area, open Timing & shape, move the playhead, and press Starts here and Ends here (or the \[ and \] keys). The area only appears between those times. To cut the video itself, use the scissors under the preview. ### Pixelate or blur: which is safer for privacy? Black box is the safest because nothing of the original remains. Large pixel blocks are next. Light blur or very small blocks can leave faces and text recognisable, so use a strong setting (around 20 px or more) for anything sensitive. ### Can pixelation be reversed? Pixelation throws detail away, so it cannot be undone exactly. Weak pixelation of text or a familiar face can still be guessed, though, so use larger blocks or Black box for passwords, plates, and IDs. ### How do I hide text, licence plates, or a screen? Choose Part of the video, drag a box over it, and pick Black box or a large block size. If it moves, select Track movement automatically and the box follows it. ### Can I blur the background and keep one person clear? Yes. Draw an area over the person (or find their face), then turn on the "everything except the boxes" switch under More options. The rest of the frame is pixelated or blurred. ### Will pixelating reduce the video quality? Only the areas you cover change. The rest of the picture is re-encoded at a high bitrate so it stays very close to the original. Under Export settings you can pick a smaller size or file if you prefer. ### Will the audio be preserved? Yes. The sound is kept (in MP4 exports it is normally copied through unchanged), or you can turn off Keep sound under Export settings to remove it. ### Does it work on iPhone and Android? Yes, in modern mobile browsers such as Safari and Chrome. Exporting long or 4K videos is faster on a computer. ### What formats are supported? MP4, MOV, WebM and MKV videos open directly. Older or less common ones, such as AVI, WMV, MPEG and camcorder MTS files, are converted on your device first. Photos can be JPEG, PNG, WebP, AVIF or iPhone HEIC. Nothing is uploaded. You can download the result as MP4, or WebM in browsers that support it.
