Frequently Asked Questions
Does compressing a PNG reduce image quality?▼
PNG compression can be lossless, meaning no quality is lost. Our tool optimizes the PNG encoding without removing any pixels. For further size reduction, you can convert to WebP or reduce colors, which may affect quality slightly.
Will my PNG transparency be preserved?▼
Yes! PNG is specifically designed for transparency (alpha channel). Our compression preserves all transparency information. Your logos, icons, and graphics with transparent backgrounds will remain intact.
What's the difference between PNG and JPEG compression?▼
PNG uses lossless compression and supports transparency, making it ideal for logos, screenshots, and graphics. JPEG uses lossy compression and doesn't support transparency, but achieves smaller file sizes for photos.
How much can I reduce a PNG file size?▼
Reduction varies based on the image content. Simple graphics with few colors can be reduced by 70-90%. Complex images with many colors might only reduce by 10-30%. Converting to WebP typically achieves 25-35% additional savings.
Is my image data secure?▼
Absolutely. All compression happens directly in your browser using JavaScript. Your images are never uploaded to any server. The processing is 100% client-side, ensuring complete privacy.
Can I compress multiple PNG files at once?▼
Yes! Switch to batch mode to compress multiple PNG images simultaneously. You can upload up to 20 images at once and download them all as a ZIP file.
