PNG files are big. A logo that looks simple can be 2-5MB. A screenshot with text is often 3-8MB. An infographic can be 10MB+. PNGs are large because they store every pixel exactly — no data is thrown away. That is great for quality. It is terrible for email, web pages, and upload limits.
Smaller PNGs. Transparency intact. Free.
Compress PNG →| Image Type | Original Size (typical) | Compressed (70% quality) | Reduction |
|---|---|---|---|
| Logo (simple, transparent) | 500KB-2MB | 100-300KB | 60-80% |
| Icon set | 1-3MB | 200-600KB | 60-75% |
| Screenshot (no transparency) | 2-8MB | 300KB-1MB | 70-85% |
| Infographic | 5-15MB | 1-3MB | 60-75% |
| UI mockup (transparent) | 3-10MB | 500KB-2MB | 60-70% |
PNG uses lossless compression by default — every pixel is stored exactly as it is. This is why PNGs look perfect but weigh a lot. JPG, by contrast, throws away visual information the eye barely notices, which is why JPGs are much smaller.
The trade-off: PNG supports transparency and JPG does not. If you need transparent areas (logos on clear backgrounds, icons for UI design), PNG is the only common option. That is why compressing PNGs matters — you need the format but not the file size.
If your PNG does not have transparency (screenshots, photos saved as PNG), you get better compression by switching to JPG. A 5MB PNG screenshot can become a 300KB JPG at 75% quality. The tool handles both formats, so try both and compare.
Rule of thumb: transparency required = keep as PNG. No transparency = JPG gives smaller files.
