FAQ

Frequently Asked Questions

What is the difference between PNG and JPG?

PNG uses lossless compression and supports transparency. JPG uses lossy compression without transparency. A JPEG copy may be smaller for photos, but savings and visual changes depend on the image.

Will I lose transparency when converting PNG to JPG?

Yes. JPG does not support transparency. Any transparent areas in your PNG will become white (or the background color) in the converted JPG file.

Can I convert multiple PNG files at once?

Yes. You can upload and convert multiple PNG images in one go. All converted JPG files are packaged into a ZIP for convenient download.

Will my images lose quality when converting to JPG?

The converter uses Canvas JPEG encoding at quality 0.92. This is an encoder parameter, not 92% retained quality. Text and edges may change, and no fixed size reduction is guaranteed. Keep the original PNG if exact source pixels matter.

Are my images uploaded to a server?

Selected images are converted locally, without uploading them for conversion. Offline use depends on all required scripts being cached; browser storage can be cleared or evicted. Site analytics and resource requests are separate.
