Are PNG files uploaded?
No. Decoding, background compositing and JPG encoding happen locally.
Tools
Convert PNG to JPG
Convert still PNG images to JPG and choose the colour placed behind transparent areas.
Choose still PNG images and convert them to JPG locally. Because JPG has no transparency, transparent pixels are filled with the background colour you select. PNG animation, if present, is treated as a single still frame.

Check the preview and dimensions before using the downloaded image.
Re-encoding does not retain the original EXIF metadata. Colour profiles and rendering may change; keep your original file.
Output limits: 60 MB per image and 100 MB in total per batch. These limits help control browser memory use.
Use this focused route when JPG compatibility or smaller photographic files matter more than PNG transparency.

Why did the background change?
Transparent pixels must be replaced because JPG has no alpha channel.
