PNG to JPG Converter
Convert PNG images to JPG format with an adjustable quality level. Runs entirely in your browser — nothing is uploaded. Transparent areas are filled with white, since JPG doesn't support transparency.
How it works
- Drop one or more PNG files into the box above, or click to browse your device.
- Adjust the quality slider if you want a smaller file size, then click "Convert to JPG".
- Download the converted JPG files individually, or as a ZIP if you selected more than one.
About this conversion
JPG uses lossy compression and doesn't support transparency, so this tool fills transparent areas with white before encoding. Lowering the quality slider produces a smaller file at the cost of some visible compression artifacting — 85% is a reasonable default for photos; drop it lower for thumbnails or previews where file size matters more than fidelity.
Conversion happens by drawing each image onto an HTML canvas and re-encoding it as JPEG, entirely on your device.
Frequently asked questions
What happens to transparent parts of my PNG?
They're filled with white, since the JPG format has no alpha channel. If you need to keep transparency, JPG isn't the right target format — consider WebP instead.
What quality setting should I use?
85% is a good balance for most photos. Go higher (95-100%) for images you'll edit further, or lower (50-70%) for web thumbnails where smaller file size matters more than fine detail.
Is there a file size or file count limit?
Each file must be under 25MB, and you can convert up to 40 files in one batch, since processing happens in your browser's memory rather than on a server.
