FAQ
How do I convert PNG to ICO?
Upload your PNG image, pick the ICO output preset, then click Convert & download. You can also resize and compress the image during conversion.
Will converting change quality?
ICO can be lossless or lossy depending on the preset. If you choose a lossy preset (like JPG or WebP lossy), lowering quality can compress the image more but may reduce detail.
Can I resize while I convert?
Yes. Set width and/or height. If you set only one dimension, the converter preserves aspect ratio.
What size should my PNG be for favicon conversion?
A square PNG at 512×512 or 256×256 works best. The converter will generate multiple sizes inside the ICO file.
