Frequently Asked Questions

Is converting PNG to ICO free?

Yes. This PNG → ICO converter runs entirely in your browser and is completely free — no account, no credits, no watermark.

Which devices and platforms can I use to convert PNG to ICO?

Any modern device with a current web browser: Windows, macOS, Linux, Android, iPhone and iPad. There is nothing to install — the conversion happens locally.

Are my PNG files uploaded to a server?

No. Files never leave your device. The entire PNG → ICO conversion runs locally in your browser, so your data stays private.

Can I convert multiple PNG files at once?

Yes — batch conversion is supported. Add as many PNG files as you like and convert them to ICO in one pass, then download the results together.

What is the maximum file size?

There is no fixed server-side limit because the conversion happens in your browser. Practical limits depend on the available memory and CPU of your device.

Will converting PNG to ICO lose quality?

No. ICO is a lossless format (or used in a lossless mode here), so the original data from your PNG file is preserved bit-for-bit in the converted result.

Will transparency be preserved when converting PNG to ICO?

Yes. Both PNG and ICO support alpha-channel transparency, so transparent areas of your file are kept unchanged in the ICO output.

How will the file size change after converting PNG to ICO?

Both formats use comparable compression, so the ICO output will be similar in size to your PNG file — typically within 10–20% of each other.
