Favicon Resizer: related tools
Draws one image onto ten square canvases at the sizes browsers, iOS and Android actually request: 16, 32, 48, 64, 96, 120, 144, 180, 192 and 512 pixels. Each canvas is re-encoded as a PNG and offered as its own download. The source image is read through an object URL into a canvas element in the page, so the file is never uploaded and nothing leaves the machine.
Favicon Resizer: how to use it
- Click Choose File and pick a square image, ideally a PNG of 512x512 or larger.
- Press Generate sizes. Each canvas is drawn with image smoothing set to high, which makes the most difference at 16px.
- Download what you need. The filenames follow the platform conventions, so apple-touch-icon.png is the 180px file and android-chrome-512x512.png is the 512px one.

Favicon Resizer: when to use it
- You changed a logo and need the whole icon set again without opening an image editor.
- A PageSpeed or Lighthouse report is asking for apple-touch-icon and android-chrome icons your site does not have yet.
- You want 16px and 32px tab icons as PNGs to point at with a link rel=icon tag instead of shipping a .ico.
Favicon Resizer: what it does not do
- The output is PNG only. It does not write a .ico file, so browsers that only look for /favicon.ico still need one - rename an output or add the link tags to your head.
- The canvas is square and the image is drawn at full width and height, so a non-square source is stretched rather than cropped or padded.
- The ten sizes are fixed. There is no field for a custom dimension and no quality control, since the output is lossless PNG.
