Frequently asked questions
Are my PNG images uploaded?
All work happens locally in the browser; no upload is required.
Can I convert PNG to ICO online?
Yes. This page opens the converter with ICO selected as the output format.
Will PNG to ICO make the file smaller?
ICO output can be smaller or larger depending on compression, transparency, colors, and image dimensions. Preview the result before saving.
Can I control ICO output quality?
ICO does not use the same quality slider as JPG or WebP. File size depends more on dimensions, transparency, colors, and the encoder.
Does ICO keep transparency?
ICO can preserve transparency when the browser can decode the uploaded PNG file and the source image contains alpha data.
Why can large PNG files fail to convert?
Browsers limit memory and canvas size. Try smaller dimensions or fewer files if conversion fails.
