PNG to JPG Converter
Choose PNG files and each one is saved as a JPG on your device, with transparent areas filled in a colour you pick.
Free tools that run in your browser. Nothing you type, open or create is uploaded to NerdBible or anyone else.
Choose one or more images to start. Nothing is uploaded.
Same format compresses each image and keeps its type. Choose JPG, PNG or WebP to convert every image to that format instead. Up to 50 images at a time.
How to use it
- Choose or drop one or more images.
- Keep Same format to make the files smaller, or choose JPG, PNG or WebP to convert them.
- Set the quality (70 to 80 suits photos) and, if you like, a max width: large photos shrink, smaller ones are never enlarged. For JPG, pick the colour that fills transparent areas; for SVG files, the width of the picture.
- Check the result for each file and download them one by one or all together.
Questions
What happens to the transparent background?
JPG cannot store transparency, so transparent areas are filled with the background colour you choose before converting. White is the default; pick another colour if the image will sit on a coloured page.
Which quality setting should I use?
For photos, 70 to 80 gives a small file that looks the same at normal size. For screenshots, text or line art, use 85 or more so edges stay clean.
Can I convert many PNG files at once?
Yes, up to 50 at a time. Each file shows its new size, and you can download them one by one or all together.
About this tool
What happens when a PNG becomes a JPG
JPG is a lossy format made for photos. It makes files much smaller by discarding fine detail that is hard to see, which is why a PNG photo often shrinks to a fraction of its size.
- Transparency is filled. JPG has no transparent pixels, so clear areas are painted with the background colour you choose, white unless you change it.
- Quality is yours to set. 70 to 80 suits photos. For screenshots and images with text, 85 to 95 keeps letters clean, because JPG compression shows around sharp edges first.
- Size usually drops a lot for photos. For flat graphics, logos and screenshots, a JPG can look worse and save little, so PNG or WebP may be the better format there.
When to convert
Use JPG when a website, form or printer asks for it, when an email attachment is too large, or when you are sending photos that were saved as PNG by a phone or an app. Keep the PNG for logos and anything that needs a transparent background.
Each JPG is redrawn from the pixels, so metadata in the PNG is not carried over.
