PNG to JPG Converter
Free PNG to JPG converter. Turn PNG images into much smaller JPG files instantly in your browser. Private, fast, no signup or watermarks needed.
About this tool
PNG files are large because they store every pixel perfectly. For photos and web uploads, JPG gives you nearly identical looks at a fraction of the size. This free converter switches any PNG to an efficient JPG in one click.
Everything runs in your browser, so your images are never uploaded and your files never leave your device. No signup, no watermarks, no waiting in a queue.
How to use
Choose a PNG image from your device and click Convert to JPG. The tool instantly produces a high-quality JPEG at 92 percent quality and gives you a download link.
One thing to know: JPG does not support transparency, so any see-through areas become white. For photos and screenshots on solid backgrounds this changes nothing, but skip this conversion for logos that need a transparent background.
The math behind it
PNG uses lossless compression: every pixel is stored exactly, which is precise but bulky. JPEG uses lossy compression: it discards subtle detail the eye barely sees, which shrinks photos dramatically with almost no visible change.
The tool draws your PNG onto a canvas, paints white behind any transparent areas, since JPG cannot store transparency, and re-encodes at 92 percent quality. The result keeps the full resolution while typically cutting the file size by half or more.
