About the PNG to JPG
This tool decodes your PNG with Imagick, flattens it onto a white background, and encodes it as JPG at quality 90. The flattening step matters: JPG has no concept of transparency, so any transparent or partly transparent pixel must be resolved against something, and that something is white.
The payoff is size. A photograph saved as PNG is often several times larger than the same image as JPG for no visible benefit, which slows pages down and fills up inboxes. If you want to choose the quality yourself rather than accept 90, compress image gives you a slider. For the web specifically, image to WebP beats both formats on size.
Where this is the wrong tool: logos with transparent backgrounds, screenshots, diagrams and anything with text or hard edges. Those either need the transparency they are about to lose, or will pick up visible fringing around sharp edges, because JPG smooths exactly where PNG was crisp. The conversion is lossy and one-way — the discarded detail is gone, and converting back gains nothing. Metadata is stripped. Up to 30 images per batch, several returning a ZIP. Files are uploaded, processed under random names in a folder blocked from web access, and deleted when the request ends. 20 MB each, 25 MB total.
Frequently asked questions
What happens to transparent areas?
They are filled with solid white, because JPG cannot store transparency. If you need the transparency, keep the PNG.
Why does my screenshot look fuzzy afterwards?
JPG compression is tuned for photographs and struggles with sharp text edges, producing faint halos around them. Screenshots and diagrams are better left as PNG.
How much smaller will it be?
It depends entirely on the content. Photographic PNGs often shrink dramatically; a flat-colour logo may barely shrink, or even grow, since PNG is already efficient at that.
What quality is used?
A fixed 90, which is high. For control over the size-versus-quality trade, use the Compress Image tool instead.
Are my images kept?
No. They are uploaded to our server, converted, and every temporary file is deleted at the end of the request.
