Frequently Asked Questions
What is a PNG image compressor?
A PNG image compressor reduces the file size of PNG images while preserving quality. PNG supports transparency and lossless compression, making it ideal for logos, icons, and graphics. Our compressor optimizes PNG files for faster web loading.
Is it safe to compress PNG images online?
Yes. All compression happens directly in your browser using client-side processing. Your images never leave your device, ensuring complete privacy.
Can I compress PNG images without losing transparency?
Absolutely. ImgSquash fully preserves the alpha channel (transparency) in PNG images during compression. Your transparency data remains intact.
What's the difference between lossy and lossless PNG compression?
Lossless PNG compression reduces file size without any quality loss — ideal for graphics and logos. Lossy PNG compression achieves smaller files by allowing minimal, imperceptible quality changes — best for photos saved as PNG.
