Turns one image into a ZIP of square PNG icons at 16, 32, 48, 64, 128, 192 and 256 pixels. Non-square images are centre-cropped to a square rather than stretched, and everything is done in your browser.

One source image becomes seven square PNG files, 16 through 256 pixels, bundled in a single ZIP named by size.
Each size is drawn separately from your original, not shrunk from the previous one, so small icons are not built from an already-blurred copy. Files are named favicon-16x16.png, favicon-32x32.png, up to favicon-256x256.png. The size list is fixed. There is no slider or checkbox for picking sizes, and no .ico or manifest file is created.
The tool centre-crops any non-square image to a square; it accepts one image per run.
The image is scaled so it fully covers the square, then the extra edge is trimmed evenly. A 1600 x 900 banner therefore loses its sides. Transparency in PNG or WebP sources carries into the PNG output. • One file at a time • Any image type the browser can decode, plus HEIC/HEIF via an on-demand decoder • Starting from a square image of about 512 px or larger gives the cleanest small sizes
It suits a quick set of web and PWA icons; it is the wrong tool for iOS or Android launcher icons or for a .ico file.
Good fits: a small site or blog that needs a 32 px tab icon plus a 192 px icon for a web manifest; a designer who wants several PNG sizes of a logo without opening an editor. For phone launcher icons with the size lists Apple and Android expect, use App Icon Generator. To trim a logo into a square yourself before generating, use Image Crop. For a single custom size, Image Resizer is simpler.
Tiny sizes lose detail no matter what tool makes them, and this one gives no preview.
Fine lines and small text in a logo will blur at 16 and 32 px. There is no preview of the results before download, so open the ZIP and check the smallest file. The tool does not add padding or background colour; transparent areas stay transparent, which can look different on dark and light browser tabs.
No. The output is a ZIP of PNG files only. Modern browsers accept PNG favicons through a link tag in your page head, but if you specifically need favicon.ico or an Apple touch icon file, this tool does not produce one.
No. The page shows the size list, but it is fixed at 16, 32, 48, 64, 128, 192 and 256 pixels. Every run gives you all seven; delete the ones you do not need from the ZIP.
The image is scaled up until it covers the square and the overflow is cropped equally from both sides. A wide logo will lose its left and right edges, so pad it to a square in an image editor first if the whole shape must stay visible.
No. The resizing and the ZIP packaging both happen in your browser tab. Nothing is sent to a server for this job.
