Convert a PNG to JPEG — transparent areas become white — with a quality slider to control file size.
Nothing is uploaded.
JPEG doesn't support transparency, so any transparent areas are filled with white in the converted image.
JPEG files are typically much smaller for photographic content, which matters for faster page loads, smaller email attachments, or meeting a file size limit.
JPEG compression can slightly soften sharp edges and fine text at lower quality settings — keep the quality slider high if your image has important fine detail.
This tool processes one image at a time to keep quality control precise per image; for bulk conversion, repeat the process for each file.
