Are my uploaded images uploaded to any server?

No. The entire conversion process occurs right inside your browser tab using client-side JavaScript and Canvas APIs. Your images never leave your local device.

What is the difference between PNG and JPG?

PNG files are lossless and can become excessively large (several megabytes) when containing complex photographic content. Conversely, JPG compresses photographic pixel color gradations efficiently, cutting bandwidth and storage dramatically.

Can I convert multiple PNG files in batch?

Yes, you can select or drop multiple files simultaneously and convert them all in one go.
