▶FAQ7 questions
What is Pixelate Image Online?
An online image pixelate tool. Adjustable block size for privacy protection, face blurring, and censoring. All processing runs locally in your browser. Supports multiple input formats with one-click copy or download. All operations run locally in your browser — no uploads.
Can a pixelated image be restored?
No — pixelation is irreversible. The original details are permanently obscured.
Is the mosaic effect secure enough?
For face recognition and text reading, large enough pixel blocks are effective. Keep in mind that advanced image tools may still attempt reconstruction.
Are my images uploaded?
No. Everything runs in your browser using the Canvas API — images never go through any server.
What pixel sizes are available?
From 2x2 to 100x100 blocks. Larger blocks create more abstract, mosaic-like effects.
Can I pixelate part of the image?
Currently the entire image is pixelated. For partial, use an editor with layer masks.
Is it good for privacy?
Yes. Large blocks (20x20+) effectively obscure faces, license plates, and sensitive info.
