FAQ

Common Questions

Is transparency preserved? +
Yes! When you keep the output as PNG, transparency (alpha channel) is fully preserved. If you switch to JPG output, transparent areas become white.
What's the difference between PNG, JPG and WebP output? +
PNG keeps transparency and is lossless at 100% quality. JPG is smaller but loses transparency. WebP gives the best file size with good quality — perfect for web use.
Is my image uploaded to a server? +
No. All processing happens locally in your browser using the HTML5 Canvas API. Your images never leave your device.
Can I compress multiple PNGs at once? +
Yes! Upload multiple PNG files and they'll all be compressed together. Download them individually or as a ZIP.

How to Compress PNG Images Online

Compressing a PNG with PDFSnip reduces its file size significantly while keeping the image visually identical. Upload your PNG, and our tool applies lossless compression — removing unnecessary metadata and optimizing the file structure — without changing a single pixel.

Why Compress PNG Images?

PNG files are popular for logos, screenshots, and images with transparency — but they tend to be large. Compressing PNGs can reduce their size by 30–70% while keeping them perfectly sharp. Web developers compress PNGs to improve page load speeds, which directly affects Google PageSpeed and Core Web Vitals scores.
