Resize Image to 16×16 Pixels
16×16 is the size of a browser-tab favicon and of small toolbar and menu icons. At this size every pixel counts: the image is fitted inside a transparent 16×16 square without stretching, resampled with Lanczos to keep edges as crisp as possible, and saved as PNG. Simplify a detailed logo to its initial or symbol first for the best result.

Frequently asked questions
Should I use this for my favicon?
It gives you one 16 px PNG. Browsers on high-density screens prefer 32 px or larger, so for a complete favicon set (favicon.ico, Apple touch icon, manifest icons) use the Favicon Generator.
Why does my logo look blurry at 16 px?
Thin lines and small text cannot survive being reduced to 16 pixels. Use a simplified mark, or try Nearest neighbour resampling under More options if the source is already pixel art.
Are my images uploaded anywhere?
No. Processing happens inside your browser with WebAssembly and Web Workers. The site only downloads the app code and codecs; your files never leave your device. You can confirm this with the live upload counter on the tool, or in your browser's network panel.
Can I process many files at once?
Yes. Drop a whole selection or folder. Files are processed in parallel on several worker threads, each result can be downloaded on its own, and everything can be saved as one ZIP.
Is it free? Is there a file limit or watermark?
It is free with no account, no watermark and no daily limit. The only limit is your device's memory: very large images (over roughly 100 megapixels) may be refused to keep the tab from crashing.
