How to Convert PNG to JPG
- Add your images — Drag and drop PNG files into the upload area, or click "browse files" to select them from your computer. You can add as many images as you like.
- Set quality — Use the quality slider to balance file size vs. image quality. 85% is a great default. Lower values produce smaller files.
- Download — Images are converted instantly. Save them individually or click "Download All" to get the entire batch.
Why Convert PNG to JPG?
PNG files use lossless compression, which preserves every pixel but results in large file sizes. JPG uses lossy compression that produces dramatically smaller files — often 5-10x smaller than the original PNG. Converting to JPG is the right choice when:
- You need smaller files — JPG files are much smaller, making them ideal for email attachments, website images, and social media uploads where file size matters.
- You don't need transparency — JPG doesn't support transparent backgrounds. If your image doesn't use transparency, JPG is the more efficient format.
- Photos and photography — JPG was designed for photographs. The compression is optimized for real-world images with gradients and natural colors.
- Website performance — Smaller images mean faster page loads. Converting PNG photos to JPG can significantly improve your site speed.
PNG vs JPG: Key Differences
PNG uses lossless compression — larger files, but zero quality loss. Supports transparency. Best for graphics, screenshots, logos, and images with text.
JPG uses lossy compression — much smaller files, with a slight quality trade-off. No transparency. Best for photographs, web images, and anywhere file size matters.
What Happens to Transparent Areas?
Since JPG doesn't support transparency, any transparent areas in your PNG images will be filled with a white background during conversion. This is the standard behavior for PNG to JPG conversion and matches what Photoshop, GIMP, and every other image editor does.
Choosing the Right Quality Setting
The quality slider lets you control the trade-off between file size and image quality:
- 95-100% — Near-perfect quality, larger files. Best for prints or professional photography.
- 85-90% — Excellent quality, great file size reduction. Best for most uses.
- 70-80% — Good quality, significant size reduction. Great for web images and social media.
- 50-65% — Noticeable compression, very small files. OK for thumbnails or previews.
