About Blur & Pixelate / 关于本工具

Before sharing a screenshot or photo, you often need to hide something: a face, a phone number, an ID or bank-card number, a home address, a license plate. This tool lets you paint over those areas and replace them with a mosaic (chunky pixel blocks) or a heavy blur. Crucially, it doesn't just cover the pixels with a layer you could peel back — it destroys the underlying detail, so the hidden information genuinely can't be recovered from the saved image.

分享截图或照片前,你常需要遮住某些东西:一张脸、电话号码、身份证或银行卡号、家庭住址、车牌。本工具让你在这些区域涂抹,用马赛克(粗块状像素)或重度模糊替换它们。关键在于,它不是用一层能被揭开的图层盖住像素——而是销毁底层细节,因此被遮信息确实无法从保存后的图片中还原。

Pixelate or blur? / 用马赛克还是模糊?

Use a strong mosaic for anything that must stay private — text, numbers, faces — because light blur can sometimes be partially reversed by software, whereas coarse pixelation throws the data away. A gentle blur is fine for softening a background or de-emphasising bystanders. Either way, check the result at full size before sharing: make sure no edge of the sensitive text peeks out beyond the masked area.

凡是必须保密的——文字、号码、人脸——用强力马赛克,因为轻度模糊有时能被软件部分还原,而粗马赛克会把数据丢弃。轻模糊适合柔化背景或淡化路人。无论哪种,分享前都按原图大小检查一遍:确认敏感文字的边缘没有露在遮盖区之外。

FAQ / 常见问题

Can the mosaic be reversed? 马赛克能被还原吗?
A strong mosaic destroys the data and can't be recovered; avoid light blur for secrets. 强马赛克销毁数据无法还原;机密别用轻模糊。
Pixelate or blur for an ID number? 身份证号用马赛克还是模糊?
Use a strong mosaic — it's the safest for text and numbers. 用强马赛克,对文字和号码最安全。
Is the original image uploaded? 原图会上传吗?
No, all masking happens locally in your browser. 不会,遮盖全部在浏览器本地完成。
