FAQ

PNG to ICO, answered.

Will I lose quality converting PNG to ICO?

PrivateRemix preserves your content faithfully during the conversion. Text, images and layout are carried across as cleanly as the formats allow.

Does PNG keep transparency?

Yes. PNG stores a full alpha channel, so transparent backgrounds are preserved. Formats like JPG do not support transparency and will fill it with a solid colour.

What size should a favicon be?

A favicon commonly bundles 16×16, 32×32 and 48×48 pixel versions. PrivateRemix produces an ICO ready to drop into your website.

Do my files get uploaded when I convert PNG to ICO?

No. PrivateRemix runs entirely on your Mac using its own processor. Your PNG files never leave the device — there is no server to upload to, and it works fully offline.

Can I convert several PNG files to ICO at once?

Yes. Drop in a batch of PNG files and PrivateRemix converts them all locally, saving each new ICO next to its original.
