PNG to ICO, explained
Convert PNG to ICO directly on your device. Create a real ICO container for an application or icon workflow that accepts PNG-backed icons. Inspect small lettering, sharp borders and partly transparent edges. Photographs and flat graphics can respond very differently to the same output format.
Choose PNG files and confirm the preview.
Keep ICO selected. Review the output behavior below before converting.
Convert and download the ICO results. Multiple results can be saved together as a ZIP.
Reading your PNG source
PNG is useful for screenshots, diagrams and transparent graphics. The tool reads the decoded raster and alpha channel. Animated PNG input produces a still image; motion and frame timing are not retained.
Settings for ICO output
The picture is fitted proportionally into a 256 × 256 canvas, centered with transparent padding. Smaller images can be enlarged; no additional detail is created. The output contains one PNG-backed icon entry.
Dimensions in PNG to ICO
Decoded source dimensions determine the aspect ratio inside the 256 × 256 icon. Source image limits still apply before fitting, so a huge input cannot bypass the 24-megapixel limit simply by choosing ICO.
What survives the conversion
Every ICO output is 256 × 256 pixels. This is not a multi-size icon bundle, and some older applications may require other icon sizes or a different representation. Inspect small lettering, sharp borders and partly transparent edges. Photographs and flat graphics can respond very differently to the same output format.
Batch processing and device limits
Choose up to 50 files, each at most 64 MB. Decoded images must fit 24 megapixels and 16,384 pixels per side; total outputs are capped at 256 MB. All conversion runs on this device. Source metadata is removed, and damaged or unsupported variants can fail without changing the originals.
