The tool places each PNG on a white background and saves it as a JPG at the quality on the slider. Width and height do not change. Any transparent parts, such as the corners of a rounded screenshot or the area around a logo, become white, because JPG has no way to store transparency.

PNG is perfect for sharp graphics with few colours, but it is a poor fit for photos and detailed screenshots, where it keeps millions of slightly different pixels without any compression trick. That is why a single phone screenshot can be larger than a whole camera photo. Saving it as a JPG lets the file drop to a size forms and email accept.

Text in screenshots stays readable at quality 70 and above; below 50 you may see faint smudges around letters. If you need a strict limit such as 100 KB, convert first and then use Compress Image to KB, which finds the best quality under the limit for you. To change the width and height as well, open Resize Image.

Keep the PNG if the image has a transparent background you still need, such as a logo for a slide; PNG to WebP shrinks it while keeping transparency. To go back to PNG later, JPG to PNG does that, though it cannot restore detail the JPG left out. A set of pages can also become one document with PNG to PDF.

Conversion runs in your browser on your device, and the images are never sent anywhere, which suits screenshots of bank pages, chats or private documents. The tool is free for personal use, takes up to 20 images per task and needs no account.
