PNG to JPG — Reduce File Size for Faster Web Performance
PNG is a lossless format, which makes it excellent for graphics, logos, and images with transparency. However, this also makes PNG files incredibly heavy. JPG uses lossy compression to create much smaller files, making it the standard for photographs on the web.
Our free PNG to JPG converter allows you to quickly shrink your image file sizes for faster page loading, easier emailing, and lower bandwidth usage. Everything runs locally in your browser — no upload, no sign-up, complete privacy.
Why Convert PNG to JPG?
According to the MDN Web Docs on Image Types, PNG is designed for exact reproduction (lossless), while JPG is designed for photographs (lossy). Here is why you should convert:
| Feature | PNG | JPG |
|---|---|---|
| Compression | Lossless (large files) | Lossy (small files) |
| Best For | Graphics, text, logos | Photographs, web images |
| Transparency | Yes (alpha channel) | No (requires background fill) |
| File Size | Larger | Smaller |
What happens to transparency?
- JPG does not support transparent backgrounds.
- When you convert a PNG with transparency, the empty areas must be filled.
- Use the Background Color selector in the tool to choose what color fills the transparency (White is standard).
- If you need transparency on the web, consider converting to WebP using our JPG to WebP tool instead.
