Free Online PNG to WebP Converter

The Tooloogle PNG to WebP Converter shrinks PNG images — especially the large transparent ones used for icons, logos, screenshots, and UI assets — into much smaller WebP files without losing the alpha channel or visual quality.

Why Convert PNG to WebP?

PNG is a great format for transparency and lossless quality, but the files are often huge. WebP supports both lossless compression and alpha-channel transparency at much smaller file sizes — a typical PNG icon shrinks by 25–50%, and full screenshots can shrink by 80% or more.

Features

Drag & drop — upload one or many PNG files.
Lossless mode — pixel-perfect WebP output that's smaller than the original PNG.
Lossy mode — further size savings for photos and complex graphics where pixel-perfect isn't required.
Transparency preserved — alpha channels survive both lossless and lossy modes.
Quality control — tune the lossy quality level (60–100%).
Batch processing — convert many files at once; download as a ZIP.
Browser-based — runs locally; no uploads.

How to Use

Drop one or more PNG files (or click to browse).
Pick lossless or lossy mode (lossless is safe for icons / UI; lossy works well for screenshots).
Review the file-size savings.
Download individual files or a ZIP.

Common Use Cases

Reducing the size of icon libraries used in apps and websites. Shrinking screenshots for documentation. Optimising UI mockups before sending to clients. Preparing transparent logos for performance-sensitive web pages.

Privacy

Conversion runs entirely in your browser. Your images never leave your device.
