How does the watermark blur tool work?
The tool lets you draw and position a blur box over a specific region of your video or image. This is especially useful for censoring watermarks, date stamps, logo overlays, or sensitive details.

How It Works
Applying blur masks on media
Adding a blur filter is one of the most reliable and non-intrusive ways to censor watermarks, stamps, date logs, or third-party brand logos. This tool lets you place a resizable blur window at any location on your media, configure its width/height, and apply a smooth Gaussian-like box blur.
The tool runs fully in-browser using GPU-accelerated canvas filter features. It decodes frame-by-frame, overlays the filter on the designated coordinate bounding box, and packages it into your finished video or image locally, ensuring zero wait lists or server overhead.
Step-By-Step
Apply a blur mask in 3 steps
- 01Upload a target video (MP4) or image file from your device.
- 02Position the blur box by selecting Auto-Detect, Preset Corners, or dragging it manually.
- 03Adjust width, height, or blur radius sliders to cover the mark, preview the result, and download the finished media.
Frequently Asked Questions
Can I change the size and intensity of the blur?
Yes. You can adjust the width and height of the blur zone via sliders, and control the blur radius (intensity) from subtle blurring to complete censoring.
Does it support auto-detection of watermarks?
Yes. You can select Auto-Detect to automatically snap the blur box to standard corner watermark positions (like Gemini or Veo corner logos) based on the media dimensions.
Are my video or image files uploaded to any servers?
No. All rendering, canvas manipulation, decoding, and encoding run entirely in your web browser using HTML5 Canvas and the WebCodecs API. Your files never leave your device.
