FAQ
Frequently asked questions
How do I convert PNG to ICO?+
Upload your PNG file (or drag it onto the box above), wait a few seconds while StandardsPDF converts it in your browser, then download the ICO. There is nothing to install and no account required.
Is converting PNG to ICO free?+
Yes. PNG to ICO conversion is free on the StandardsPDF free tier – no watermark, no signup, and no credit card. A Pro tier lifts the file-size and daily limits if you need more.
Will the ICO keep the quality of my PNG?+
StandardsPDF aims for the highest fidelity the ICO format allows, so your image comes through looking as close to the original as possible. Some format-specific details may adapt where ICO works differently to PNG.
Does the ICO from my PNG keep transparency?+
When PNG and ICO both support an alpha channel, transparency is preserved. Converting PNG to a ICO without transparency flattens those areas onto a white background.
What is the maximum PNG file size I can convert to ICO?+
Up to 100 MB per PNG on the free tier and 2 GB on Pro. If your PNG is larger, split it first or upgrade for the higher limit.
Can I convert several PNG files to ICO at once?+
Yes – add multiple PNG files and StandardsPDF processes them as a batch, returning a ICO for each.
Can I convert PNG to ICO on my phone?+
Yes – the PNG to ICO converter is fully responsive and works in Safari, Chrome and other modern browsers on iOS, Android and iPadOS.
How long does a PNG to ICO conversion take?+
Most PNG files convert to ICO in a few seconds. Larger or higher-resolution files take a little longer, but there is never a queue on the free tier.
