Pixelate Image
Pixelate Image. Free, no signup, no watermark. Runs in your browser — your file never leaves your device.
How to pixelate image
- Add your image — Drop it onto the box above, or click to open your file picker. On a phone this opens the camera roll directly.
- Set the options — Adjust the settings shown beneath the upload area. The defaults suit most files.
- Run the tool — Press the button. Processing happens on your device and normally finishes in well under a second.
- Download the result — Save the file. The original on your device is untouched — the tool never modifies what you put in.
What this tool does
To use the pixelate image, add your image to the tool above and the result is ready to download in a moment. Everything runs in your browser, so nothing is uploaded. The tool is free, needs no account, applies no watermark, and has no daily limit.
What this tool does
This is a single-purpose editor: it does one thing, it does it in one step, and there is nothing to learn. Pixelate Image happens on an HTML canvas in your browser, at the image's original resolution, and the result downloads as a PNG or JPEG. There is no account, no project to save and no watermark — which is the difference between this and opening a full editor for a thirty-second job.
Why nothing is uploaded
This tool runs entirely on your own device. Your file is read into memory by JavaScript on this page, processed there, and handed back to you as a download. It is never transmitted to us, which means there is nothing on our side to store, log, leak or forget to delete.
You can verify that yourself: load this page, disconnect from the internet, and the tool still works. That is a different claim from a privacy policy promising prompt deletion, and it is the reason this site exists.
What it costs
Nothing. There is no account, no email capture, no free-trial countdown, no watermark on the output and no daily limit. The site is funded by advertising, which sits below the tool and never between an input and its result.

Works offline
Because everything runs locally, this tool keeps working once the page has loaded even if your connection drops. That is worth knowing on a train, on conference WiFi, or anywhere the network is unreliable — and it is the clearest demonstration that your file really is not going anywhere.
