PNG to JPG Converter

Convert PNG images to JPG (JPEG) format instantly. Transparent backgrounds become white.

What is the PNG to JPG Converter?

The PNG to JPG tool converts PNG images into JPG, drastically reducing file size while keeping visual quality high. PNG is lossless and great for editing, but the resulting files can be many megabytes. JPG uses lossy compression to slim images down for the web, email and messaging apps.

This tool is ideal when you need to share photos over WhatsApp, upload them to a portal with a small file-size limit, or store thousands of images without eating up disk space. It flattens any transparent background against the colour of your choice — usually white.

Conversion happens entirely in your browser. Nothing is uploaded, so private screenshots, product photos and identity documents stay on your device.

How to use the PNG to JPG Converter

  1. 1Drop your PNG files into the upload area or click to browse.
  2. 2Adjust the JPG quality slider (typically 80–90% is a sweet spot).
  3. 3Choose a background colour to replace any transparent pixels.
  4. 4Click "Convert to JPG" and preview the result if the tool offers it.
  5. 5Download the JPG version — the tool automatically renames the file.

Frequently asked questions

Does the JPG lose quality?

Yes — JPG is lossy. At 90% quality the loss is imperceptible for most photos.

What happens to transparency?

Transparent pixels are replaced with the background colour you pick (white by default).

Can I convert multiple images at once?

Yes. Drop as many PNGs as you like and download each JPG individually or as a ZIP if provided.

Will the JPG be sharp for logos and text?

For images with hard edges, keep PNG. JPG can blur those slightly at lower qualities.

Does the tool re-encode images already in JPG?

It only touches PNG files. JPG inputs are ignored to prevent needless quality loss.
