JPG, PNG, WebP, SVG, GIF, and browser-readable images.
Mobile processing guidance
On mobile, start with one browser-readable image under 10MB before trying larger files.
10MB recommended limit.; keep very large images under browser memory limits.
Canvas-based image operations can fail when pixel dimensions, file count, or browser memory are too high.
If generation fails, retry with fewer images, smaller dimensions, JPG/WebP output, or lower quality.

Use PNG to ICO Converter to turn a square PNG into an ICO container with PNG image data.
For production favicons, also create multiple sizes and test in browsers.
Square source
Use a 256 x 256, 512 x 512, or 1024 x 1024 PNG.
Transparent icon
PNG transparency can carry into the ICO payload.
Favicon testing
Use this for quick favicon and shortcut experiments.
Favicon trial
Convert a 512px logo PNG to ICO for quick testing.
Shortcut icon
Create a local desktop shortcut icon from a PNG.
Limit
Older systems may prefer multi-size ICO files.
Using non-square images
Icons usually need square source art.
Expecting a full favicon pack
Use the Favicon Generator for multiple sizes and web manifest assets.
Ignoring edge padding
Icons need enough transparent margin to avoid looking cramped.
Favicon testing
Make a quick ICO from a PNG logo.
Shortcut icons
Create simple icon files for local use.
Brand QA
Check whether a logo remains readable at small sizes.
Web publishing
Pair ICO output with favicon generator assets.
Does PNG to ICO Converter upload my image?
The public tool is designed for browser-side processing based on the current implementation. Avoid using sensitive images unless you have reviewed the implementation and your own data requirements.
Will metadata be preserved?
Canvas-based exports usually change or remove metadata. Keep the original file when metadata, color profiles, or exact camera details matter.
Why can a browser image tool fail?
Very large files, unusual formats, limited memory, unsupported browser encoders, or SVG features the browser cannot render can cause failures.
When should I use PNG to ICO Converter?
Use it when you need a quick single-image ICO from a square PNG source.
