Question 1

What is the difference between PNG and JPG?

Accepted Answer

PNG uses lossless compression and supports transparency (alpha channel), making it ideal for logos and icons. JPG uses lossy compression generating smaller files, preferred for photographs.

Question 2

When should I convert PNG to JPG?

Accepted Answer

When the PNG file is too large and you need to reduce size for email, social media, or websites. If the image has no transparency, the resulting JPG will be significantly smaller.

Question 3

Does the conversion lose PNG transparency?

Accepted Answer

Yes. JPG does not support transparency. Transparent areas will be filled with a solid color (usually white). If you need to keep transparency, convert to WebP instead.

Question 4

Are my images uploaded to a server?

Accepted Answer

No. All processing happens directly in your browser. No images are sent to our servers.

Question 5

Can I control the quality of the generated JPG?

Accepted Answer

Yes. In the settings you can adjust the quality parameter between 0 and 1. The default value of 0.7 provides good quality with reduced size.
