Pixelate Image: what it does
Pixelation replaces part of a photo with large single-colour blocks: the classic way to hide a face or a licence plate on TV, and a popular retro look for a whole picture. Choose how many blocks fit across the photo, from 6 (huge blocks) to 160 (fine mosaic). Pixelate the whole image, or choose “Selected areas” and drag over just the parts to hide. It runs in your browser at full resolution, so your photo is never uploaded.
How to use it
- Drop a photo into the box, paste it with Ctrl+V, or tap to choose one from your phone.
- See the effect straight away. The thumbnails show every other effect on your photo too.
- Adjust the settings, and hold “Hold to compare” to see the original.
- Download at full resolution as JPG, PNG or WebP.
Tips
- To hide a face, choose few blocks across the photo, so the face is covered by only a handful of blocks (about 5 to 8 across the face).
- Fine pixelation (lots of small blocks) can leave a face recognisable, especially from a distance. Go coarser for privacy.
- For a deliberate 8-bit look with a limited colour palette, use the pixel art effect instead.
- Save pixelated images as PNG to keep the block edges crisp.
Frequently asked questions
How do I pixelate part of a picture?
Add your photo, choose “Selected areas”, and drag over the part to pixelate. Add as many areas as you need, then set the block size with the slider and download.
Can pixelation be reversed?
Not exactly: each block keeps only one average colour, so the detail is gone. But with fine pixelation a face or text can still be guessed, so use big blocks, or a black bar for anything truly sensitive.
Is my image uploaded?
No. The pixelation is done in your browser on your own device. Nothing is sent to our servers.
