PNG to JPG Conversion: The Quality Settings Guide

Converting PNG to JPG is one of the most common image tasks — you have a large PNG screenshot or photo and need a smaller file for email, web, or sharing. But what quality setting should you use? Will you lose important details? Here's the complete guide.

Why Convert PNG to JPG at All?

PNG uses lossless compression, which is great for quality but results in large files. A photograph saved as PNG might be 8–20 MB. The same photo as JPG at 85% quality could be 500 KB–2 MB — a reduction of 70–90% with virtually no visible difference.

For photos, JPG is almost always the right choice. For logos, screenshots, and graphics with text, PNG is usually better. The decision comes down to your image content.

The Quality Settings: What Each Level Does

Quality	File Size	Visual Quality	Best For
95–100%	Large	Near-lossless	Professional print, archiving
85–90%	Good	Excellent (recommended)	Most uses, web, sharing
75–80%	Small	Good	Web pages, fast loading
60–70%	Very small	Acceptable	Thumbnails, previews
Below 60%	Tiny	Visible artifacts	Use only when size is critical

When NOT to Convert PNG to JPG

PNG is better than JPG for these image types — don't convert them:

• Screenshots with text — JPG blurs text edges; PNG keeps them sharp
• Logos and icons — JPG creates blocky artifacts around clean edges
• Images with transparent backgrounds — JPG fills transparency with white
• Images you'll edit multiple times — each JPG save degrades quality
• Charts, diagrams, and infographics — lines and text stay clearer in PNG

The 85% Rule: Why It's the Sweet Spot

Extensive testing by image quality researchers has shown that 85% JPG quality is the "perceptual quality threshold" — the point at which virtually no human viewer can detect any difference from the original. Going above 85% produces larger files with no visible benefit. Going below 80% starts showing subtle artifacts on sharp edges.

PNG To JPG defaults to 85% for exactly this reason. For most conversions, you don't need to change it.
