About PNG to JPG

PNG files are great for graphics with transparency, but they tend to be much larger than JPGs — especially for photographs. A single PNG photo can easily be 5-10 MB, while the same image as a JPG might be under 1 MB. Converting PNG to JPG can dramatically reduce file size (often 60-80% smaller) while maintaining good visual quality. This makes JPG the better choice for sharing photos by email, uploading to social media, or embedding in documents where transparency is not needed. This tool lets you adjust the compression quality slider to find the perfect balance between file size and image quality. Preview the result before downloading to make sure it meets your standards.

Frequently Asked Questions

Why convert PNG to JPG?

JPG files are typically 60-80% smaller than PNGs for photographs. If your image doesn't need transparency, converting to JPG dramatically reduces file size — great for email attachments, social media, or web use.

Does PNG to JPG lose transparency?

Yes. JPG does not support transparency. Transparent areas in your PNG will be filled with a white background. If you need to keep transparency, consider WebP instead.

What quality setting should I use?

For photographs, 80-85% quality is a good balance of size and quality. For images with text or sharp edges, use 90-95% to avoid compression artifacts around edges.

Is my file uploaded to a server?

No. Transmute processes everything locally in your browser using JavaScript and the Canvas API. Your files never leave your device — there is no server, no upload, no cloud processing.
