How it works
PNG to JPG reads the PNG structure in your browser, decodes its content into an in-memory representation, then re-encodes that data as JPG. Both the decode and encode steps of PNG to JPG run on your device, so nothing is transmitted and accuracy never depends on network conditions.
Frequently asked questions
What happens to transparency?
JPG does not support transparency. Transparent pixels flatten onto a solid background you choose.
Is the conversion lossy?
Yes. JPEG uses lossy compression; pick your quality level in the tool.
What happens to PNG transparency?
JPG has no alpha channel, so transparent pixels are flattened against a background color you choose (white by default).
Can I set the JPG quality?
Yes. Slide from 40 (small) to 95 (near-lossless). The preview updates so you can compare visually.
Does the tool strip metadata?
EXIF, ICC, and XMP metadata are removed by default for privacy; toggle to keep them if needed.
Can I batch convert multiple PNGs?
Yes. Drop many PNGs at once; the ZIP output mirrors the source filenames with .jpg extensions.
