Why convert PNG to JPG
PNG stores every pixel exactly, so photos and large screenshots saved as PNG are heavy. JPG compresses photos far better: the same picture is often several times smaller, and almost every website, upload form and print shop accepts it.
Choosing the quality
Around 90, most photos look the same as the PNG; 75 to 85 is plenty for the web. Text and sharp lines in screenshots show JPG artifacts sooner, so keep those at 90 or above, or keep them as PNG and shrink them with Arche's optimizer.
What happens to a transparent background?
JPG can't store transparency, so transparent areas become white. Convert to WebP instead if you need to keep them transparent.
Are my images uploaded?
No. The conversion runs inside your browser, so your images stay on your device. Files are only uploaded if you choose to optimize them with Arche, and those are deleted within 48 hours.
What is Arche?
Arche makes JPEG, PNG and WebP images smaller without changing their format or pixel size, and strips metadata such as EXIF location. It is free without an account; Pro raises the batch limits.
