Why pixelate instead of blur?
Pixelating replaces an area with large mosaic blocks, each block one flat colour. It's the classic 'censored' look you see on TV and in news photos. Compared with a blur, a pixelated area reads more clearly as deliberately hidden — useful when you want it to be obvious that something was removed.
You control the block size with a slider: bigger blocks hide more detail. Pixelate the whole image, or drag a box over just a face, a plate, or a logo. Each block is the average colour of the pixels beneath it, so the result blends naturally with the surrounding image.
How to pixelate an image
- Open your image. Drag it onto the tool, choose a file, or paste it.
- Select the area. Choose Selected areas and drag a box over each part to censor, or use Whole image.
- Set the block size. Slide the block size up until the detail is gone, then download.
Bigger blocks hide more
Small blocks can leave faces or text partly legible. For anything sensitive, increase the block size until you can't make out the underlying detail — or use Redact for a guaranteed solid cover.
Come funziona pixelate image
- Cosa fa
- Pixelatura a mosaico (media dei blocchi)
- Come lo fa lo strumento
- Lo strumento divide l'area selezionata in una griglia di blocchi quadrati e riempie ogni blocco con l'unico colore medio dei pixel sottostanti — il classico mosaico 'censurato' — con una dimensione del blocco che controlli da un cursore (minimo 2 px).
- A cosa serve
- La pixelatura si legge chiaramente come una censura deliberata, perciò è la scelta consueta per censurare in stile telegiornale un volto, una targa o un logo quando vuoi che sia evidente che qualcosa è stato nascosto.
- Si può invertire?
- Ogni blocco è una media di pixel reali, quindi blocchi piccoli possono lasciare un volto o un testo in parte leggibili e a volte sono stati ricostruiti: ingrandisci i blocchi finché non resta alcuna struttura.
Suggerimento: Aumenta la dimensione del blocco finché la forma sottostante non si dissolve del tutto; un volto nascosto dietro pochi blocchi grandi è molto più sicuro di uno dietro tanti blocchi piccoli.

Domande frequenti
What does pixelating do?
It divides the selected area into a grid of large blocks and fills each one with the average colour beneath it, creating a mosaic that hides fine detail.
Is pixelating safer than blurring?
With large enough blocks it hides detail well, but like blur it can occasionally be partly reversed at light settings. For true secrecy, use the Redact (solid bar) mode.
Can I pixelate only a face?
Yes. Choose Selected areas and drag a box over the face; only that region becomes a mosaic. Add more boxes for more faces.
Where is my image processed?
The blurring happens in your browser, so the new file is created on your own device. How any data associated with the tool is handled is described in our privacy policy.
