FAQ
How do I do this for free?
Choose the image and this page samples it and groups the pixels into its most common colours — on your device with no upload, no watermark and no account.
Is my image uploaded anywhere?
No. Everything happens in your browser using the canvas API and nothing is transmitted or stored, which you can verify by turning off your Wi-Fi. That is the whole point of an on-device image tool.
Why does an on-device tool matter for photos?
Photos are personal and can carry hidden metadata. Processing them locally means they are never sent to a server, so nothing can be logged, cached or leaked.
What formats are supported?
Any image your browser can open — PNG, JPEG, WebP and more — is read and processed locally.
Limits
Runs in the browser, so extremely large images are limited by your device's memory; the output is a standard PNG or JPEG.
