PNG to JPG converter

Convert PNG images to lightweight JPG/JPEG format directly in your browser. Because JPG does not support alpha transparency, transparent areas are smoothly filled with your chosen background color (white by default, preventing unexpected black backgrounds). Adjust JPEG quality from 10% to 100% to balance file size and visual fidelity. All encoding happens on your device using HTML5 Canvas — your images are never uploaded to any server.

100% Client-Side ConversionRuns locally in your browser canvas. No images are uploaded to any server.

PNG to JPG converter FAQ

What is a PNG to JPG converter?
A PNG to JPG converter changes a PNG image into a JPG file. JPG is a lossy image format that is usually much smaller than PNG for photographs, and it has no transparency. This one converts PNG to JPG locally in your browser, with adjustable quality and a background color for transparent pixels. Nothing is uploaded.
Does this PNG to JPG converter upload my images to a server?
No. All image decoding and re-encoding are performed locally inside your browser using the HTML5 Canvas API. Your pictures never leave your device and are never sent over the internet.
How does this tool handle transparent backgrounds in PNGs?
The JPEG format does not support alpha transparency channels. When converting a transparent PNG, transparent pixels are automatically painted with your selected background color (white by default, with custom color support) so you never get unwanted black backgrounds.
What does the JPEG quality slider do?
The slider adjusts the lossy compression level passed to canvas.toBlob() from 0.10 (10% quality, smallest file size) to 1.00 (100% quality, maximum visual fidelity). An 80% to 85% setting is generally optimal for web photos and documents.
Can I convert multiple PNG files at the same time?
Yes. You can select or drag and drop multiple PNG files into the converter. You can then download converted JPGs individually or download the entire batch as a single ZIP archive.
Why should I convert a PNG to a JPG?
PNGs use lossless compression, which can make photographs and complex illustrations very large. Converting to JPG significantly reduces file sizes (often by 70% to 90%), making pages load faster and reducing email attachment sizes.
How do I convert PNG to JPG programmatically in JavaScript?
Load the PNG into an Image element or ImageBitmap, create an HTMLCanvasElement with matching dimensions, fill the context with a background color using fillRect(0, 0, width, height), draw the image with drawImage(), and call canvas.toBlob(blob => ..., 'image/jpeg', quality).
Are there any file size or resolution limits?
The only limits are your device's memory and browser canvas size capabilities (most modern desktop and mobile browsers comfortably handle images up to 16,384 x 16,384 pixels).
