Frequently Asked Questions

What happens to transparency when converting PNG to JPG?

Because JPEG does not support transparency, transparent areas are filled with your chosen background color (default is white).

Why should I convert images to WebP?

WebP provides superior compression compared to PNG and JPG, creating files that are typically 25% to 35% smaller.

Are my photos uploaded to a server?

No. The conversion is performed entirely within your web browser using HTML5 Canvas.

Is there any daily limit on conversions?

No. You can convert as many images as you need for free.
