Mark the areas you want to hide with rectangles, ellipses, or a brush, and choose how: pixelate, blur, mosaic, or solid cover. You see the result instantly.

Careful with sensitive data
When you save, a JPG or WebP is recompressed as a whole: at 95% you will barely notice. PNG loses nothing.

How to use it
- Drag your photo into the box, choose a file, or paste it with Ctrl+V. JPG, PNG, WebP, GIF, AVIF, and BMP are supported.
- Pick a tool (rectangle, ellipse, or brush) and mark what you want to hide on the image. You can add as many areas as you need.
- Change the effect and its strength: pixelate, blur, mosaic, or solid cover. To move or adjust an area, use “Select”.
- Check the safety notice for each area and download the image as JPG, PNG, or WebP. It is saved without the camera data.
Frequently asked questions
Is my photo uploaded to a server?
No. The pixelation is calculated in your own browser. The image is not sent anywhere, so you can censor documents, screenshots, or photos of other people with peace of mind.
Can I pixelate only part of the image?
Yes, that is the idea. Mark one or more areas with a rectangle, ellipse, or brush and only those are pixelated. The rest of the image does not change by a single pixel. If you would rather pixelate everything, use the “Pixelate whole image” button.
Can pixelation be reversed?
It depends on how coarse it is. Light pixelation or a blur can be partly recovered with enhancement software. For sensitive data, such as an ID number, a license plate, or a password, use “Solid cover” or large blocks. Each area shows whether it is safe or weak.
What is the difference between pixelate, blur, and mosaic?
Pixelate turns the area into blocks of a single color. Blur softens it smoothly. Mosaic is pixelation with thin lines between the blocks, like tiles. Solid cover paints a flat color and leaves nothing of the original image.
What happens to the photo’s data, such as its location?
When you save, the image is generated again from scratch and does not keep EXIF data such as the GPS location, camera model, or date. That helps when you are going to post the photo online.
What is the maximum image size?
Up to 30 MB per file. Images larger than 16 megapixels are scaled down a little so your phone’s browser does not run out of memory. The result is saved at the size the image was worked on.
When to pixelate an image
Pixelating hides information before you share a photo or a screenshot: a person’s face, a car’s license plate, an account number, an email address, or the name on an invoice. You mark only that area and the rest of the image stays intact.
Pixelate, blur, or solid cover
- Solid cover: the safest option. Nothing is left of the original area.
- Pixelate with large blocks: makes a face unrecognizable. If the blocks are small, enhancement software can rebuild part of the content.
- Blur: it looks tidy, but it is the weakest. Use it for looks, not to protect data.
Tips for censoring well
Cover a little more than the data itself: include edges, shadows, and reflections. If there are several pieces of data, mark each one separately. After saving, open the resulting image and check that nothing can be read before you share it.
How to mark the areas
Choose the rectangle, the ellipse, or the brush and drag over the image. If you would rather not use a mouse, select “Add area”: it creates a centered area that you can move with the arrow keys and grow or shrink with the plus and minus keys. Each area has its own effect and its own strength, so you can cover a license plate with a solid color and pixelate a face with large blocks in the same image.
What happens to the photo’s data
When you save, the image is exported without the camera data (location, phone model, and date). With the Original format, a JPG is recompressed as a whole; at high quality the difference is not noticeable. If you need the pixels outside the areas to stay exactly the same, choose PNG. To shrink the file afterward, use the image compressor.
Pixelate the whole image
If you want to apply the effect to the entire image, for example for a retro-style thumbnail, use “Pixelate whole image”. The bigger the block size, the less detail is left; the tool shows how many pixels each block is in your image. For other touch-ups, try the photo editor, or write on the picture with Add text to image.
Everything on your device
Photos with sensitive data should not travel across the internet. Here the pixelation happens in your browser: the original image is not uploaded or stored.
