Privacy and cleanup note
This tool runs in your browser with local JavaScript. Your files or pasted lines do not need to leave your device for the main operation.
Use the visible Reset, 清除, Remove, or Delete local result controls when you finish. Large files can still be limited by device memory, browser canvas limits, or mobile performance, so test sensitive work with non-confidential samples first.

How to use this tool
- Upload a screenshot or image.
- Increase block size for stronger privacy masking or a more retro style.
- Preview before downloading so hidden details are actually unreadable.
- Use compression afterward if you need a smaller web-ready file.
Who this helps
Helpful for SEOs and content teams sharing screenshots, support teams masking data, and creators making retro-style visuals.

常问问题
Is pixelation reversible?
Pixelation is a visual masking effect, not a cryptographic privacy guarantee. Stronger block sizes make details harder to read, but for highly sensitive information you should crop, cover, or remove the content before sharing.
Does this tool upload my screenshot?
不. The selected image is decoded and pixelated with browser canvas on your device. The page does not need to upload the screenshot for the pixelation preview or PNG export.
