Frequently Asked Questions
How do I convert PNG to JPEG?
Add your PNG file, choose the available conversion settings, start the conversion, and download the completed JPEG file.
Why convert PNG to JPEG?
JPEG is accepted by nearly every website, form, email service, photo application, and device. It is particularly useful for photographs and other images where a compact, widely compatible file is helpful.
What happens to transparent areas in my PNG?
JPEG does not support transparency. Crest Convert fills transparent and semi-transparent pixels with your selected background colour. White is selected by default, and you can choose any other colour before converting.
What JPEG quality should I choose?
The default setting is a good choice for most images. Choose a higher value when fine detail matters, or a lower value when a smaller download is more useful. The completed file size is shown after conversion.
Will JPEG usually be smaller than PNG?
For photographs and detailed images, usually. Screenshots, logos, text, and graphics with flat colours can behave differently, so the result depends on the image and selected JPEG quality.
Can I resize the JPEG while converting?
Yes. Keep the original dimensions, choose 75%, 50%, or 25%, or enter a custom percentage from 10% to 100%. The width and height change together so the image keeps its proportions.
