A PNG to JPG converter is an online tool that transforms Portable Network Graphics (PNG) files into JPEG format. PNG uses lossless compression and supports transparency, while JPG uses lossy compression and removes transparency, resulting in much smaller files ideal for photographs and web use.
The converter reads your PNG file, flattens any transparent areas to a solid background (usually white), applies JPG compression, and downloads the result. JPG compression removes redundant colour information invisible to the human eye, drastically reducing file size without noticeable quality loss on photos.
| Input | Result | Notes |
|---|---|---|
| PNG screenshot with transparency, 2.4 MB | JPG version, 245 KB | 90% size reduction; transparent areas become solid background; ideal for email attachments |
| PNG portrait photo, 1.8 MB | JPG version, 180 KB | 90% smaller; visual quality nearly identical; suitable for social media upload |
| PNG graphic with text and sharp lines, 850 KB | JPG version, 120 KB | 86% reduction; slight softening of edges; best for photos, not crisp graphics |
JPG uses lossy compression, which removes some colour data. For photographs, the loss is invisible at quality levels 85–90%. Diagrams, text, and images with transparency will show noticeable degradation—use PNG for those.
JPG does not support transparency. The converter fills transparent areas with a solid colour (default white). You can change this via the background colour picker before converting.
Yes, but quality does not improve. Once PNG is converted to JPG, some data is lost; converting back to PNG will not restore it. Always keep your original PNG if you might need it later.
For web images, aim for 50–300 KB; for social media, 100–500 KB is standard. The quality slider controls the final size; experiment to find your balance.
Yes. The converter processes images in your browser; they are never uploaded to a server. Your file is automatically deleted after conversion.
No, JPG does not support animation. Only the first frame will be converted. For animated images, stick with PNG or use a GIF converter.
