Yes. PNG to JPG is free with no account, no watermark, and no conversion limit. You can convert as many PNG images to JPG as you like. The tool runs in your browser at no cost, so there is no paid tier required and no cap that appears after you have converted a few images.

What happens to transparent areas?

JPG cannot store transparency, so any transparent pixels in your PNG are filled with a solid background, typically white, during conversion. This is fine for photographs and flattened graphics. If you need to keep transparency, such as for a logo that sits over other content, leave the image as PNG instead of converting it.

How much smaller will the file be?

Often much smaller, because JPG uses lossy compression while PNG is lossless. A photographic PNG can shrink by half or more, depending on the quality level you choose. Flat graphics with few colors may not shrink as much. You can see the new file size in the result and adjust quality if you want more savings.

Does converting lower the quality?

JPG is lossy, so a small amount of detail is discarded to save space, but at a high quality setting the change is usually invisible for photographs. Lower settings compress more and can introduce soft artifacts. To keep things clean, convert once from the original PNG rather than repeatedly re-saving the JPG.

Are my images uploaded?

No. PNG to JPG converts locally in your browser. The image is drawn to a canvas, re-encoded as JPG in memory, and returned as a download without being sent to a server. Nothing is stored or logged, so personal photos and screenshots stay private on your device and are cleared when you close the tab.

Does it work on mobile?

Yes. PNG to JPG is responsive and runs in mobile browsers with no app. You can select a PNG from your phone, choose a quality level, and download the JPG directly. Because the conversion happens on your device, nothing is uploaded, and the controls stay touch-friendly on screens as narrow as 375 pixels.

PNG to JPG is a free online tool that converts PNG images into compact JPG files in your browser, shrinking large graphics for faster sharing while flattening transparency onto a solid background.

Why convert PNG to JPG

PNG files can be very large because they are lossless, which is wasteful for photographs that do not need pixel-perfect edges. Converting to JPG applies efficient lossy compression, often cutting the file size dramatically, which speeds up email, uploads, and web pages. JPG is also the most universally accepted photo format across devices and platforms.

What happens to transparency

JPG does not support transparency, so any transparent areas in the PNG are filled with a solid background, usually white, during conversion. This is fine for photos and flattened graphics but means a logo meant to sit over other content should stay as PNG. Knowing this avoids the surprise of a white box appearing behind a transparent image.

Quality and compression

JPG quality is adjustable, trading sharpness for size. A high setting keeps photos looking clean while still saving space, and a lower setting maximizes compression for thumbnails and previews. Because JPG is lossy, repeated re-saving gradually softens an image, so convert once from the PNG master rather than editing the JPG over and over.

Private and local

PNG to JPG runs in your browser. The image is drawn to a canvas, re-encoded as JPG locally, and returned as a download. Nothing is uploaded or stored, so your images never leave your device. The conversion completes in a fraction of a second for a typical photo.
