PNG to JPG: How to Convert Images Online for Free
Need to convert PNG images to JPG? Here's the fastest way — plus when you should and shouldn't convert.
Why Convert PNG to JPG?
PNG files are often 5-10x larger than JPG files with the same visual content. Converting makes sense when:
- Uploading to websites that require JPG format
- Sending via email where file size matters
- Saving storage space on your device
- Social media — most platforms prefer JPG
When NOT to Convert
Keep your PNG if:
- The image has transparency (JPG doesn't support transparency)
- It's a logo or icon with sharp edges (JPG adds artifacts)
- It's a screenshot with text (JPG blurs text)
- You need to edit it again later (lossy compression degrades with each save)

File Size Comparison
We tested with a typical screenshot (1920×1080):
| Format | File Size | Notes |
| PNG (original) | 2.8 MB | Lossless, perfect quality |
| JPG (95%) | 320 KB | Virtually identical |
| JPG (85%) | 180 KB | Great quality, much smaller |
