FAQ
よくある質問
私の画像はアップロードされますか?
No. The image is decoded, processed, and exported locally with browser APIs. It is not sent to MediaKit or a third-party server.
複数のエリアを保護できますか?
Yes. Add up to six independent regions. Select an area from the settings panel, then move or resize it in the preview.
どのエフェクトを使えばいいのでしょうか？
Blur is softer and blends into the image. Pixelation makes the hidden area more obvious and works well for text or small details.
Does this detect faces automatically?
No. This tool gives you manual control so you can choose exactly what to hide. Move and resize a region over each detail you want to protect.
どの出力形式を選択すればよいですか?
PNG is best for lossless quality and transparency, JPG is broadly compatible and usually smaller, and WebP is useful for modern websites.
Can I blur an animated GIF?
The first frame is used for the preview and the export. Use a video tool if you need to protect moving content frame by frame.
Is the blur permanent?
The downloaded image contains the rendered effect. Still review the full result before publishing, especially around high-contrast edges.
