PNG to JPG converter — convert PNG images to JPG online

This free PNG to JPG converter exports your PNG file as a JPG image with a white background replacing any transparent areas. JPG is a compressed format that produces significantly smaller file sizes than PNG, making it better suited for web uploads, email attachments, and social media posts where transparency is not needed.

The conversion runs entirely in your browser using the HTML5 Canvas API — your file is never uploaded to any server.

When to convert PNG to JPG

  • Reduce file size for faster website loading — JPG is typically 60–80% smaller than the equivalent PNG
  • Upload to platforms that only accept JPG or JPEG format
  • Email attachments where file size limits are a concern
  • Product photos for e-commerce where transparency is not needed
  • Blog and article images where smaller size improves page speed

What happens to transparent areas

JPG format does not support transparency. All transparent pixels in the source PNG are automatically filled with a white background before the JPG is created. If you need a different background colour, fill the transparent area in an image editor before converting.

How to use PNG to JPG Converter

  1. Upload or drag and drop a PNG image into the tool.
  2. Adjust the Quality slider — 80–85% gives a good balance for most web images.
  3. Click Process & Download — the JPG file downloads automatically.
  4. Check the output file size shown to confirm the reduction meets your needs.
