Goed voor
Gezichten, kentekenplaten, chatberichten, schermen, adressen en andere details die privé moeten blijven.
Hoe het werkt
Bedek elk gevoelig detail met een aparte selectie. Op elk frame in de geëxporteerde video worden dezelfde gebieden en vervagingssterkte toegepast.

Kies een subtiele of sterke Gaussiaanse vervaging voor de inhoud.
Controleer elk gebied en render vervolgens lokaal een nieuwe MP4.
De browser decodeert, vervaagt en codeert elk frame lokaal met MediaBunny en WebCodecs. Je bronvideo wordt nooit geüpload.
FAQ
Nee. De geselecteerde video wordt lokaal in uw browser gelezen en verwerkt. Het wordt niet naar MediaKit of een server van derden verzonden.
Ja. Voeg maximaal zes onafhankelijke gebieden toe en plaats elk gebied of wijzig het formaat voordat u het exporteert.
The current version applies fixed areas to every frame. For a moving subject, use a larger area or export shorter segments with the video trimmer.
De originele audiotrack blijft behouden als de MP4-uitvoer en de browsercodec dit ondersteunen.
Every frame must be decoded, composited, and re-encoded. High-resolution or long videos need more CPU time and memory; closing other heavy tabs can help.
Video blur guide
This free video blur tool lets you cover one or more fixed areas in a video and export a new MP4. Use it for faces, license plates, private messages, addresses, screens, or any detail that should not be visible. No account or upload is required.
The picker accepts common phone, camera, screen-recording, and editing-app exports. Actual decoding depends on the video codec supported by your browser.
Best compatibility
Recommended for phones, messaging apps, social platforms, and most browsers.
Apple and camera exports
Useful for iPhone, iPad, and camera footage; output is converted to MP4.
Web-friendly video
A good choice for browser recordings and modern web projects.
Existing media files
Accepted up to 2 GB; support depends on the codecs inside the container.
Protect a video in four steps. The source remains on your device throughout the workflow.
Drop one MP4, MOV, WebM, MKV, AVI, or M4V file into the tool.
Move the selection over a sensitive detail. Add up to six areas and resize each one with its corner handles.
Play the preview, use arrow keys for precise positioning, and adjust the blur strength.
Render a new MP4 locally. Download it when the progress reaches 100%.
A fixed blur area works well when a sensitive detail stays roughly in the same place throughout a clip.
Hide email addresses, chat messages, customer data, API keys, or notifications before sharing a tutorial.
Cover a face, vehicle plate, badge, or home number in footage for a quick privacy edit.
Hide unreleased product details, account identifiers, or private dashboards in a recording.
Prepare event footage, street scenes, or user-generated clips before posting publicly.
The selected File is passed to a local Web Worker. MediaBunny reads the container, WebCodecs decodes and encodes the video, and OffscreenCanvas composites the blur on each frame. The source and result stay in your browser; nothing is uploaded or stored on our servers. Remove the file or close the tab when you are finished to release memory.
FAQ
Yes. You can blur a video and download the MP4 result for free, without signing up.
Yes. Add up to six independent fixed areas. Select an area from the settings panel, then move or resize it in the preview.
Not yet. The current workflow applies fixed areas to every frame. Use a larger box, shorter segments, or the video trimmer when the subject moves.
The tool exports MP4. The video is re-encoded so the blur can be applied frame by frame, while the original audio is kept when browser support allows it.
A container can hold many different codecs. Even when the extension is accepted, your browser may not have a decoder for the video or audio stream. MP4/H.264 is the most reliable input.
The downloaded MP4 contains the rendered blur. Still review the result before publishing, especially if the sensitive detail is large, high-contrast, or moves outside the selected area.
Blurring requires decoding, compositing, and encoding every frame. Resolution, duration, frame rate, and the number of areas all affect processing time.
