About PNG Format
PNG files are often significantly larger than necessary. A typical screenshot is 1–5 MB. Design exports from Figma or Photoshop can exceed 10 MB. PNG uses lossless compression by default, but many tools produce suboptimal compression ratios.
About Compressed PNG Format
Optimized PNG files achieve 30–70% smaller file sizes. Lossy PNG compression reduces the color palette from millions to thousands of colors. The visual difference is imperceptible for most images. Lossless optimization rearranges data for better compression without any quality change.
Why Convert PNG to Compressed PNG?
Compress PNG images to reduce website load time. Improve Google PageSpeed and Core Web Vitals scores. Reduce bandwidth costs for image-heavy websites. Meet file size requirements for upload forms. Optimize screenshot collections for documentation.
Common Use Cases
- ✓ Website performance optimization
- ✓ Reducing screenshot file sizes
- ✓ Email attachment size reduction
- ✓ Documentation image optimization
- ✓ Design asset compression for handoff
- ✓ App store screenshot optimization
Frequently Asked Questions
How much smaller will compressed PNG files be?
Typical reduction is 30–70%. A 3 MB PNG screenshot compresses to 1–2 MB with lossy compression. Lossless optimization achieves 10–30% reduction by improving compression efficiency.
Does PNG compression reduce quality?
Lossy mode reduces the color palette, causing imperceptible quality changes for most images. Lossless mode reorganizes pixel data without any visual change. Both options are available.
Is PNG or JPG better for website images?
PNG is better for graphics, logos, screenshots, and images with text. JPG is better for photographs. For web-optimized alternatives, consider WebP which is smaller than both PNG and JPG.
Does compression remove transparency?
No. PNG transparency (alpha channel) is fully preserved after compression. Transparent areas remain transparent in the optimized output file.
Can I compress multiple PNG files at once?
Yes. Batch compression processes multiple files simultaneously. Each file optimizes independently. Download results as individual files or a ZIP archive.
