Questions

Frequently asked questions

When should I use JPG instead of PNG?

JPG is best for photographs where a smaller file size is important. PNG is suited for images with sharp lines, text, or transparency.

What happens to transparency?

The JPG format does not support transparency. Transparent pixels are flattened onto the background colour used by the converter.

Can I convert back from JPG to PNG?

Converting the JPG back to PNG will not restore detail lost during JPG encoding.

Background

Understanding PNG to JPG Conversion

This tool converts PNG files to JPG format. You can adjust the output quality, which affects both file size and image clarity.

  • The main reason to convert from PNG to JPG is to reduce file size. JPG uses lossy compression, which is ideal for photographs.
  • The JPG format does not support transparency. When converting a PNG with a transparent background, you must choose a solid colour to fill those areas.
