How to Convert PNG to JPG (Free, No Watermark)
PNGs are often far bigger than they need to be. Converting to JPG usually fixes that in one step.
A screenshot or graphic saved as PNG can easily be 5-10x the size of the same image saved as JPG, simply because PNG isn't built to compress photographic detail efficiently. If the file doesn't need to stay lossless or transparent, converting to JPG is usually the fastest way to shrink it.
How to convert a PNG to JPG
- Upload the PNG to a PNG to JPG converter.
- Any transparency in the image is flattened onto a solid background (usually white) automatically, since JPG can't represent transparency.
- Download the converted JPG - typically a significantly smaller file.
The one catch: transparent backgrounds
If your PNG has a transparent background - a logo meant to sit on top of other content, for example - converting to JPG will fill that transparency in with a solid color, usually white. That's fine if the image is headed somewhere with its own white or light background, but it defeats the purpose of a transparent logo anywhere else. In that case, keep the PNG, or convert to WebP instead, which supports transparency at a smaller file size than PNG.
When this conversion is worth doing
- Attaching a photo to an email where attachment size matters
- Uploading to a form or portal with a file size limit
- Speeding up a webpage where the PNG is acting as a photo, not a graphic
Frequently asked questions
Why is a PNG so much bigger than a JPG of the same photo?
PNG uses lossless compression, which can't shrink photographic detail nearly as far as JPG's lossy compression can. For anything photo-like, JPG will almost always produce a noticeably smaller file at a visually similar quality.
What happens to transparency when I convert PNG to JPG?
JPG doesn't support transparency, so any transparent areas in the PNG get filled in - typically with white - when converted. If you need to keep transparency, stay on PNG or move to WebP instead.
Will converting to JPG make my image blurry?
At a reasonable quality setting, no - the difference is generally invisible for photos. It becomes more noticeable on PNGs with sharp text or flat graphic elements, which JPG compresses less gracefully than photos.
