Bagaimana cara kerjanya
Buramkan apa yang Anda perlukan
Tutupi setiap detail sensitif dengan pilihan terpisah. Area dan kekuatan blur yang sama diterapkan pada setiap frame dalam video yang diekspor.
Sesuaikan kekuatannya
Pilih Gaussian blur yang halus atau kuat untuk kontennya.
Preview and export
Periksa setiap area, lalu render MP4 baru secara lokal.
Video Anda tetap ada di perangkat ini
Browser mendekode, mengaburkan, dan mengkodekan setiap frame secara lokal dengan MediaBunny dan WebCodecs. Video sumber Anda tidak pernah diunggah.
FAQ
Pertanyaan yang sering diajukan
Apakah video saya akan diunggah?
Tidak. Video yang dipilih dibaca dan diproses secara lokal di browser Anda. Itu tidak dikirim ke MediaKit atau server pihak ketiga mana pun.
Bisakah saya memburamkan lebih dari satu area?
Ya. Tambahkan hingga enam area independen dan posisikan atau ubah ukurannya masing-masing sebelum mengekspor.
Bisakah saya memburamkan wajah yang bergerak?
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.
Apakah audionya akan disimpan?
Trek audio asli disimpan ketika keluaran MP4 dan codec browser mendukungnya.
Why is export slower for large videos?
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
Blur faces and sensitive details in a video online
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.
Supported video formats
The picker accepts common phone, camera, screen-recording, and editing-app exports. Actual decoding depends on the video codec supported by your browser.
MP4
Best compatibility
Recommended for phones, messaging apps, social platforms, and most browsers.
MOV / M4V
Apple and camera exports
Useful for iPhone, iPad, and camera footage; output is converted to MP4.
WebM
Web-friendly video
A good choice for browser recordings and modern web projects.
MKV / AVI
Existing media files
Accepted up to 2 GB; support depends on the codecs inside the container.
How to blur a video
Protect a video in four steps. The source remains on your device throughout the workflow.
- 01
Add your video
Drop one MP4, MOV, WebM, MKV, AVI, or M4V file into the tool.
- 02
Place the blur areas
Move the selection over a sensitive detail. Add up to six areas and resize each one with its corner handles.
- 03
Preview and tune
Play the preview, use arrow keys for precise positioning, and adjust the blur strength.
- 04
Export and download
Render a new MP4 locally. Download it when the progress reaches 100%.
Common use cases
A fixed blur area works well when a sensitive detail stays roughly in the same place throughout a clip.
Privacy-safe screen recordings
Hide email addresses, chat messages, customer data, API keys, or notifications before sharing a tutorial.
Faces and license plates
Cover a face, vehicle plate, badge, or home number in footage for a quick privacy edit.
Product demos and reviews
Hide unreleased product details, account identifiers, or private dashboards in a recording.
Social and community posts
Prepare event footage, street scenes, or user-generated clips before posting publicly.
How private is the processing?
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
Frequently asked questions
Is this video blur tool free?
Yes. You can blur a video and download the MP4 result for free, without signing up.
Can I blur multiple areas?
Yes. Add up to six independent fixed areas. Select an area from the settings panel, then move or resize it in the preview.
Does it track a moving face automatically?
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.
Which output format is created?
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.
Why can an AVI or MKV file fail?
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.
Does the blur permanently hide the information?
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.
Why does a long video take time?
Blurring requires decoding, compositing, and encoding every frame. Resolution, duration, frame rate, and the number of areas all affect processing time.
