Are my images uploaded to a server?

No. The entire conversion runs inside your browser using the HTML5 Canvas API. Your image never leaves your device.

What happens to transparent areas in my PNG?

JPG does not support transparency. Any transparent or semi-transparent pixels are composited over a solid white background before the JPG is generated.

What quality setting should I use?

Quality 80–85 is the sweet spot for most photos — visually near-lossless at roughly half the PNG file size. For diagrams or text-heavy images, 90+ is safer. For thumbnails or previews, 60–70 is acceptable.

Why is the JPG sometimes larger than the PNG?

PNGs with simple, flat-color graphics compress extremely well with lossless encoding. For such images, a JPG at quality 100 can be larger. Lower the quality slider or keep the original PNG for flat graphics.

Is there a file size limit?

The limit is your browser's available memory, typically several hundred megabytes. Very large images (over 30 MP) may be slow to process on low-end devices.

Can I convert multiple files at once?

This tool focuses on single-image conversion with a live quality preview. For bulk conversion, use the PNG to JPG Batch tool.

Summary

This tool converts PNG images to JPG format entirely inside your browser using the HTML5 Canvas API. No files are uploaded to any server. Transparent areas in the PNG are filled with a white background before conversion, since JPG does not support transparency. Use the quality slider to balance image clarity against file size and see an instant size comparison before downloading.
