If you are deciding between PNG to JPG, WebP to JPG, or another export path, this comparison highlights the tradeoffs between compatibility, compression, and transparency.
| Format | Best For | Compression | Transparency |
|---|---|---|---|
| JPG | Photos, marketplaces, email, and broad compatibility | Strong lossy compression | No |
| PNG | Graphics, screenshots, and transparency-sensitive exports | Lossless | Yes |
| WebP | Modern web delivery with better compression flexibility | Strong (lossy + lossless) | Yes |
Quality Presets And File Size Control
JPG quality is the main lever for size reduction. Lower settings create smaller files, while higher settings preserve more fine detail for product shots, portraits, and high-resolution uploads.
Maximum Quality (100)
Use when you want the cleanest possible JPG export and are less concerned about file size.
Balanced (85)
Recommended for most websites and marketplaces because it usually keeps detail while reducing size meaningfully.
Smaller Files (70)
A practical choice for content-heavy pages, email attachments, and faster-loading galleries.
Ultra Compact (40)
Designed for aggressive compression when small file size matters more than fine texture or edge detail.

Frequently Asked Questions
How do I convert PNG to JPG?
Upload your PNG files, keep output as JPG, adjust quality if needed, and click convert. Your browser creates JPG files locally and you can download them instantly.
What is the difference between JPG and JPEG?
JPG and JPEG are the same image format. The shorter .jpg extension became common because older systems used three-character file extensions.
What happens to transparency when converting to JPG?
JPG does not support transparency. Transparent areas are flattened onto a white background during conversion so the exported file stays broadly compatible.
Are files uploaded to Koala servers?
No. This is a local JPG converter. Files stay in your browser during conversion and are not uploaded to our servers.
