What is PNG to JPG Converter?
PNG to JPG Converter converts PNG images to JPEG format with configurable quality — dramatically reducing file sizes for photographic images. All processing runs in your browser; images never leave your device.
A PNG photo can be 5–10× larger than the same image as a quality-80 JPEG. For web delivery, converting photos to JPEG is one of the fastest performance wins available.
When to Convert PNG to JPEG
Good Candidates
Photographs, hero images, product photos, backgrounds — images with continuous tones and no transparency.
Bad Candidates
Logos, icons, screenshots, UI assets, images with text — flat colors and sharp edges show JPEG artifacts.
Transparency Warning
PNG transparent areas will be filled with white (or your chosen background color) in the JPEG output.

Quality vs File Size Reference
| Quality | File Size (vs PNG) | Use Case |
|---|---|---|
| 60 | ~15–20% | Thumbnails, previews |
| 75 | ~20–30% | Standard web images |
| 80 | ~25–35% | Recommended default |
| 90 | ~35–50% | High-quality display images |
| 95 | ~50–70% | Archival / print prep |
Tips & Common Mistakes
Set a white background for transparent PNGs. If your PNG has a transparent background and you’re converting to JPEG, set the fill color to white (or your page background color) to avoid unexpected black or white patches.
Don’t convert logos or UI screenshots to JPEG. JPEG introduces blocky artifacts on sharp edges and flat colors — text, icons, and line art look noticeably worse. Keep these as PNG.
Use quality 80, not 100. Quality 100 JPEG is still lossy (and much larger than PNG for photographic images). The perceptual difference between quality 80 and 95 is minimal; the file size difference is significant.
