Why convert PNG to JPG?
PNG is excellent for sharp graphics and transparency, but photographic PNG files can be much larger than equivalent JPEGs. JPG uses lossy compression that is optimized for photos and continuous-tone imagery, so converting PNG to JPG can make sharing, email attachments and some upload workflows more practical.
What changes during PNG to JPG conversion?
JPG does not support transparency. Transparent or semi-transparent PNG areas must be flattened against a background during conversion, so check the result before using it. JPEG is also lossy, which means lower quality settings can introduce visible artifacts around text, edges and fine detail.
| Feature | PNG | JPG |
|---|---|---|
| Compression | Lossless | Lossy |
| Transparency | Yes | No |
| Typical strength | Graphics, screenshots, transparency | Photos and broad compatibility |
| File size | Can be large for photos | Usually smaller for photos |
When JPG is the better output
- Reducing the size of photographic PNG files
- Creating a widely accepted image for forms, portals or older applications
- Preparing photos for email or messaging where transparency is unnecessary
- Converting exported screenshots only when smaller size matters more than pixel-perfect edges
How to convert PNG to JPG
- Add one or more PNG files to the converter.
- Confirm PNG as the source and JPG as the output.
- Choose quality, lossless or animation options when they apply to the selected format.
- Convert the images and download individual results or the batch ZIP when available.
Quality and file-size guidance
For photos, a quality setting around 80–90 is usually a sensible starting point. Inspect text, logos and hard edges carefully because those elements can reveal JPEG artifacts sooner than photographic areas.
Frequently asked questions
What happens to PNG transparency when converted to JPG?
JPG cannot store transparency, so transparent areas are flattened into an opaque result during conversion.
Is JPG always smaller than PNG?
No, but JPG is usually much smaller for photographs. Simple flat graphics can sometimes compress efficiently as PNG.
Which quality should I choose?
Start around 80–90 for general use and raise it when fine detail matters more than file size.
Can I batch convert PNG to JPG?
Yes. Select multiple PNG files, choose JPG as the output and convert them together.
