FAQ

What happens during PNG to JPG conversion?

The converter flattens transparency and compresses the image into a lossy JPG output.

Are uploaded files kept permanently?

No. The planned pipeline keeps files for a short retention window and serves downloads through expiring links.

Can quality or formatting change?

Yes. Each converter page calls out what is preserved, what may be lost, and which settings matter before upload.
