What is PNG to JPG Converter?

PNG to JPG converts PNG images into JPG (JPEG) files. JPEG uses lossy compression that produces much smaller files, which is ideal for photographs and detailed images where a small PNG is hard to achieve. Because JPEG has no transparency, transparent areas are filled with white.

This converter decodes your PNG with the browser's image engine and re-encodes it as a quality-92 JPEG. Nothing is uploaded to a server.

How to Use PNG to JPG Converter

1

Drop a PNG file onto the upload area or click to browse

2

The image is decoded and re-encoded as JPG instantly

3

Compare the JPG preview with your original

4

Click Download to save the JPG

Common Use Cases

  • Shrinking a large photographic PNG into a small JPG for the web.
  • Reducing file size for email or upload limits.
  • Converting a PNG screenshot or render to a compact JPG.
  • Flattening a transparent PNG onto white as a JPG.

Example Input and Output

A large photographic PNG converts to a much smaller JPG.

Input
render.png (2.6 MB, PNG)
Output
render.jpg (310 KB, quality-92 JPEG)

How This Tool Works

The browser decodes the PNG onto a canvas, flattens any transparency onto white, and exports the canvas as a quality-92 JPEG for download.

Quality

Output uses JPEG quality 0.92 — a strong balance of small size and visual fidelity.

Privacy

Your image never leaves the browser; conversion is fully client-side.

Frequently Asked Questions

Is my PNG uploaded anywhere?
No. The file is decoded and re-encoded entirely in your browser using the canvas API.
What happens to transparency?
JPG does not support transparency, so transparent areas are filled with white before encoding.
Will I lose quality?
JPEG is lossy, but this tool uses a high quality setting (92) so the loss is usually imperceptible.
How much smaller will the file be?
For photographic images, JPG is often far smaller than PNG. For flat graphics, PNG may already be smaller.
