// ABOUT PNG
PNG uses lossless compression with full alpha-channel transparency support. It preserves every pixel exactly, making it the standard choice for screenshots, logos, web graphics, and any image where precision matters. PNG files tend to be larger than lossy alternatives but guarantee no quality degradation.
// ABOUT WebP
WebP is a modern image format developed by Google that supports both lossy and lossless compression, as well as transparency and animation. Lossless WebP files are typically 25–35% smaller than equivalent PNGs, while lossy WebP achieves similar quality to JPEG at 25–34% smaller file sizes. All major browsers have supported WebP since 2020.
// WHY CONVERT
Converting PNG to WebP is useful when you need your image in a format suited for web optimisation, responsive images, progressive web apps, and any context where smaller files improve page load times. Because WebP uses lossy compression, some fine detail may be lost in the conversion — but for photographic content the difference is usually imperceptible. Image Toolz runs the entire conversion directly in your browser. Nothing is uploaded to any server — your files remain completely private on your device. The tool handles images up to 200 MB and most conversions complete in under a second.
// FAQ
What is PNG?
PNG is a lossless image format with alpha-channel transparency support, widely used for web graphics, screenshots, and images requiring precision.
What is WebP?
WebP is a modern image format developed by Google. It supports lossless and lossy compression as well as transparency, and consistently produces smaller files than PNG or JPEG at comparable quality.
Will converting PNG to WebP lose quality?
Not if you use lossless WebP, which preserves every pixel exactly. Image Toolz converts PNG to lossless WebP by default, so transparency and sharp edges are maintained with no quality loss.
Is it safe to convert my files here?
Yes. All conversion runs entirely in your browser. Your images are never uploaded to any server and nothing leaves your device.
