Why Use This Converter?

Universal Compatibility

We don’t just do one format. You can convert WebP to JPG, PNG to WebP, JPG to PNG, and every other combination in between using this single tool.

100% Private (No Uploads)

Most converter sites upload your files to a cloud server to process them. We don’t. Our tool converts your images locally in your browser. Your personal photos never leave your device.

Quality Control

When converting to JPG or WebP, you can use the Quality Slider to balance file size and image clarity. Lower the quality to save space, or keep it at 100% for maximum detail.

Frequently Asked Questions (FAQ)

How do I convert WebP to JPG?

Upload your WebP image, select the “JPG” button in the format options, and click Download. This is the most popular use for this tool.

Will I lose transparency if I convert PNG to JPG?

Yes. The JPG format does not support transparency. If your PNG has a transparent background, it will be filled with white when converted to JPG. To keep transparency, convert to WebP instead.

What is the best format for websites?

WebP is generally the best choice for websites today. It offers high quality with file sizes that are often 30% smaller than JPG or PNG.

Is there a limit on file size?

Since the conversion happens on your device, you can convert large images without hitting the “server limits” that other sites have.
