About This PNG to JPG Converter

This tool converts PNG images to JPG (JPEG) files directly inside your browser. It is designed for anyone who needs to convert PNG screenshots, graphics, or photos into smaller, more universally compatible JPG files — for example, to attach to an email, upload to a website, or reduce file size before sharing. Because the conversion runs locally using the HTML5 Canvas API, nothing is uploaded to a server and your images stay on your device.

Transparent PNG images do not have a native equivalent in JPG format, so when a transparent area is detected, the tool fills it with your chosen background color (white by default) before encoding. The quality slider lets you balance file size against image fidelity, and you can convert multiple files at once for quick batch processing.

How to Use the PNG to JPG Converter

Drag and drop PNG files onto the upload area, or click Choose PNG Files to select them from your device.
Pick a quality preset (Maximum, Balanced, Small Size, Smallest) or adjust the quality slider manually between 10% and 100%.
If your PNGs have transparency, choose the background color you want to appear behind them in the JPG output.
Click Convert All to JPG to process every file at once.
Preview the before/after results and click Download on any image, or Download All to save them together in a convenient ZIP archive.
Use the Copy button to place an individual JPG directly on the clipboard, or clear results when you are done.

Frequently Asked Questions

Why would I convert PNG to JPG?

JPG files are usually much smaller than PNG files for photographic content, because JPG uses lossy compression tuned for natural images. If you are emailing photos, uploading to a CMS, or posting on a platform with file-size limits, converting PNG to JPG often reduces the size significantly with little visible difference.

What happens to the transparent parts of my PNG?

JPG does not support transparency, so any fully or partially transparent pixels are composited onto the background color you choose in the settings. White is the default, but you can pick black, light gray, blue, or any custom color to match your design.

Which quality setting should I use?

For most uses, 80–90% quality offers a good balance of size and appearance. Use 100% if you need maximum fidelity (such as for print), or drop to 60–70% when you want smaller files for the web and can accept slightly softer edges around fine details.

Are my images uploaded to a server?

No. All conversion happens inside your browser using the HTML5 Canvas API and the browser’s built-in JPEG encoder. Your images never leave your device, and nothing is logged or stored on any server.

Is there a file size or count limit?

Each PNG can be up to 25 MB, and you can process up to 30 files at a time. Very large images may take a moment longer to encode, but there is no hard limit imposed by the tool itself beyond those practical bounds.
