Smaller Site Assets
WebP often makes PNG screenshots, UI graphics, and product images dramatically smaller, helping pages load faster and use less bandwidth.
Transparency Preserved
WebP supports alpha transparency, so transparent PNG logos and UI assets keep transparent edges instead of being flattened onto a background.
Batch Convert
Drop up to 20 PNG files at once. Convert a whole icon set, product pack, or screenshot batch and download everything as one ZIP.
Quality Slider
Tune output quality from compact to maximum. Use balanced settings for web pages or push to 100 for high-fidelity assets.
Modern Browser Format
WebP is widely supported by modern browsers and is a practical default for faster websites, especially when served alongside fallbacks if needed.
100% Private
Everything runs locally through the Canvas API. Your PNG files never leave the tab; only an anonymous conversion count is recorded.

FAQ

COMMON QUESTIONS

PNG is reliable but often large. WebP can keep similar visual quality with much smaller files, which helps websites load faster and reduces bandwidth for image-heavy pages.

Yes. WebP supports alpha transparency, and this tool draws the PNG into canvas and exports WebP without filling a background. Transparent pixels remain transparent.

The default 82 is a good web balance. Use 65 for aggressive compression, 90+ for UI screenshots or images with fine details, and 100 when you want the browser's maximum WebP quality.

Usually, especially for photos, screenshots, and complex graphics. Very tiny PNG icons or already optimized flat artwork can sometimes be similar in size or even smaller as PNG. The result list shows before and after sizes so you can judge each file.

Modern Chrome, Edge, Firefox, Safari, and Android browsers support WebP. If you support very old browsers, serve WebP with a PNG fallback using <picture> or your CMS image pipeline.

No. Conversion happens entirely inside your browser with JavaScript and the Canvas API. TPL Tools never receives your files; only an anonymous conversion counter is updated after success.
