Free Online Image Pixelator
Select areas to censor with a pixel effect or apply it to the whole image. Fast, free, and no files are sent to servers.
How to use the Image Pixelator
Upload your image by clicking the indicated area or dragging the file directly onto it. The tool accepts JPG, PNG, WebP, and static GIF formats. All processing happens in your own browser — no file is sent to external servers, ensuring full privacy.
Once the image is loaded, you'll see two modes at the top of the editor: Select area and Whole image. In selection mode, position the cursor over the image, click and drag to draw a rectangle over the region you want to censor. A green border marks the selected area. Then click Pixelate Selection to apply the effect. You can repeat this process as many times as you like, pixelating different regions before downloading the final result.
Before applying, adjust the Intensity control: lower values produce a subtler effect with small blocks; higher values create large, clearly visible pixels, ideal for more definitive censoring. Try different intensities on each area as needed.
If you want to undo the last action, use the Undo button — it works precisely, reverting exactly one step per click. If you'd rather start over, the Reset button restores the image to its original state. Once you're happy with the result, click Download and choose the output format: PNG (no quality loss), JPG (smaller file size), or WebP (best balance of quality and compression). The downloaded file will keep the original image name followed by "pixelated."
