About This PNG to WebP Converter
This free PNG to WebP converter transforms your PNG images into the modern WebP format directly in your browser. No files are uploaded — the HTML5 Canvas API processes your image locally on your device, keeping everything private.
Unlike converting to JPG, converting PNG to WebP preserves transparency. A PNG logo or icon with a transparent background will remain transparent in the WebP output, making WebP a direct upgrade over PNG for most web use cases.
WebP files are typically 25–35% smaller than PNGs at the same quality. Use the quality slider to find the right balance — 85% quality is recommended for most images. All modern browsers including Chrome, Firefox, Safari 14+, and Edge support WebP natively.
How to Convert PNG to WebP
Step 1 — Click "Choose PNG" or drag your PNG file onto the upload area above.
Step 2 — Set the quality slider. 85% gives excellent quality with noticeably smaller file size.
Step 3 — Click "Convert to WebP". Transparency is preserved automatically.
Step 4 — Download the WebP file. Use "Convert Another" to process more images.

Frequently Asked Questions
Does WebP support transparency like PNG?
Yes. WebP supports an alpha channel for transparency, just like PNG. When you convert a PNG with a transparent background to WebP, the transparency is preserved in the output file. This makes WebP an excellent alternative to PNG for transparent web images.
How much smaller will WebP be compared to my PNG?
WebP files are typically 25–35% smaller than PNG at equivalent quality. For images with photographic content, savings can be even larger. For flat-colour illustrations and icons with large transparent areas, the savings may be more modest.
Which browsers support WebP format?
All modern browsers support WebP: Chrome, Firefox, Safari (since version 14), Edge, and Opera. Over 95% of internet users are on a WebP-compatible browser. For legacy browser support, serve a PNG fallback via the HTML picture element.
Is WebP output quality adjustable?
Yes. The quality slider lets you choose from 1% to 100%. At 85% quality, PNG-to-WebP conversion produces excellent results with significantly reduced file size. Higher quality preserves more detail; lower quality creates smaller files with more visible compression.
Can I convert an animated PNG to WebP?
This tool converts single-frame PNG images only. Animated PNG (APNG) files are not supported — only the first frame will be converted. For animated image conversion, use a dedicated animated WebP converter tool.
What is WebP and why should I use it?
WebP is a modern image format developed by Google. It provides superior compression compared to PNG and JPEG, supports transparency, and is natively supported by all modern browsers. Using WebP for web images reduces page load times and improves Core Web Vitals performance scores.
Are my images uploaded to a server?
No. All conversion happens locally in your browser using the HTML5 Canvas API. Your PNG files never leave your device and are never uploaded to any server. The tool works entirely client-side and needs no internet connection after the page loads.
