Convert PNG to JPG Online Free

Q: How do I convert PNG to JPG online?

Drop your PNG file into the converter at the top of this page and it converts to JPG automatically. The conversion runs entirely in your browser — your file is never uploaded to any server.

Q: Does converting PNG to JPG reduce file size?

Yes. JPG uses lossy compression, so a photograph saved as PNG can become 5 to 10 times smaller as a JPG with no visible quality loss. AllConvert encodes at 92% quality for the best balance of size and clarity.

Q: Will I lose transparency when converting PNG to JPG?

Yes. JPG does not support transparency. Any transparent areas in your PNG will become white in the converted JPG. If you need to keep transparency, consider converting to WEBP instead.

Need to turn a PNG into a JPG? AllConvert lets you do it instantly, right in your browser. No file upload, no account, no software to install. Your image never leaves your device.

Why convert PNG to JPG?

PNG files are lossless and can be very large, especially for photographs. A 10 MB PNG photo often shrinks to under 1 MB as a JPG with no visible difference. JPG is the standard format for sharing photos by email, uploading to social media, or embedding in documents where file size matters.

What happens during the conversion?

AllConvert draws your PNG onto a browser canvas and re-encodes it as a JPG at 92% quality. This preserves sharp detail in photographs while dramatically reducing file size. One thing to keep in mind: JPG does not support transparency. If your PNG has transparent areas, they will appear as a white background in the output.

When should you keep PNG instead?

If your image is a logo, icon, screenshot, or anything with sharp text and flat colors, PNG is usually the better choice. PNG preserves every pixel exactly, while JPG compression can introduce visible artifacts around hard edges. For photographs and complex images, though, JPG is almost always the right call.

How to convert

Hit the download button that appears to save your new JPG file.

The entire process runs locally in your browser. Nothing is uploaded, and there are no file size limits beyond your device's memory. It works on desktop and mobile, in Chrome, Firefox, Safari, and Edge.

What actually happens to transparent pixels

JPEG has no alpha channel in the file format at all — it stores color as YCbCr, three channels, full stop, with nowhere to put "half see-through" information. So when a transparent or semi-transparent pixel gets encoded, the converter composites it against a solid background — white, by default here — before the JPEG compression even runs. For hard on/off transparency this is invisible. For soft-edged elements like drop shadows or anti-aliased icon edges, though, it can leave a faint light fringe, because those edge pixels were only partially see-through and get blended in rather than simply cut out.

Frequently asked questions

How do I convert PNG to JPG online?
Drop your PNG into the converter on this page and it converts to JPG automatically. It all happens in your browser — nothing gets uploaded to a server.

Does converting PNG to JPG reduce file size?
Usually, yes, often dramatically for photos — a PNG photo can shrink 5 to 10 times over as a JPG with no visible loss. AllConvert encodes at 92% quality to balance size against clarity.

Will I lose transparency when converting PNG to JPG?
Yes. JPG can't represent transparency, so any transparent area in your PNG becomes solid white in the output. Use WEBP instead if you need to keep it.
