PNG to JPG

A PNG to JPG converter re-encodes a PNG image into the JPEG format, trading PNG's lossless compression and transparency for JPEG's far smaller file sizes on photographic content. This tool runs the conversion in your browser, supports batch processing, and adds no watermark. The main reason to convert is size: PNG is lossless and stores every pixel exactly, which is great for screenshots and graphics but wasteful for photos, where a JPG can be a fraction of the size with no visible difference. There are two behaviors worth understanding before you convert. First, transparency. JPEG has no alpha channel, so any transparent areas in your PNG cannot survive. This tool flattens them onto a white background, which is the standard choice, but it means a logo designed to sit on a dark theme will suddenly have a white box around it. If you need to keep transparency, convert to WebP instead, which supports both compression and an alpha channel. Second, JPEG is lossy. The conversion discards some image information to gain its size savings, and that step is not reversible, so you cannot later convert the JPG back to PNG and recover the lost detail. For a typical photo the default high-quality encoding makes the loss invisible, but for sharp-edged graphics, screenshots with text, or flat areas of solid color, JPEG can introduce blocky artifacts and ringing around edges where PNG stayed clean. As a rule of thumb, convert photos to JPG for size, but keep screenshots, logos, and line art as PNG. Everything is processed locally with no upload, no account, and no watermark, so it is a quick, private way to prepare PNG exports and screenshots for email, web upload, or storage where the lighter JPG format is preferable.
