    FAQ

    FAQ

    What happens to transparency when converting PNG to JPG?

    JPG doesn't support transparency, so transparent areas are filled with white. Convert to PNG or WebP to keep a transparent background.

    Why convert to WebP?

    WebP files are often smaller than JPG or PNG at the same quality and support transparency, which makes them great for websites. Some very old apps may not open them.

    Can I convert HEIC photos from an iPhone?

    Only formats your browser can open can be converted. Most browsers can't open HEIC, so it may show “Read failed”. Set your iPhone camera to “Most Compatible” or export as JPG first.

    Are my images uploaded?

    No. Everything is converted in your browser and your files are never sent anywhere.
