Comment utiliser: WebP to PNG Converter
Drag and drop your WebP images into the dropzone or click to select files (batch conversion supported).
The browser engine immediately decodes the WebP bitmap and creates a lossless 32-bit RGBA PNG, preserving full transparency.
Optionally toggle 'Preserve Transparency' or select a solid background fill color if you need opaque graphics.
Preview the converted PNGs, then click 'Download .PNG' or download all converted images at once in a single ZIP archive.

Universal Compatibility: Why WebP to PNG Conversion Matters
Google introduced the WebP image format in 2010 to make the web faster by reducing photographic file sizes compared to traditional JPEG and PNG formats. Today, modern websites, social networks, and content delivery networks serve WebP images by default.
However, when you right-click and save an image from the web, you often end up with a .webp file that desktop photo viewers, video editors, and print shops refuse to accept. Converting these files into standard .png format restores full versatility without sacrificing visual quality.
How In-Browser Conversion Protects Your Privacy
Traditional online converters force you to upload personal photos, corporate mockups, or sensitive client graphics to remote cloud servers where they are saved to disk. Toolhast uses the browser’s native Canvas API to decode WebP bitstreams directly in your computer's RAM.
Because no data travels across the network, processing is instantaneous and 100% private. You can even disconnect your internet connection once the page loads, and the converter will continue to function flawlessly.
Foire aux questions
Why should I convert WebP images to PNG?
While WebP is an excellent format for fast website loading, many legacy desktop graphic programs (such as older versions of Adobe Photoshop, InDesign, and Premiere Pro) or standard office suites cannot open or edit WebP files. Converting WebP to PNG provides universal cross-platform compatibility while preserving full alpha channel transparency and sharp details.
Will converting WebP to PNG preserve transparency?
Yes, absolutely. By default, Toolhast extracts both the RGB color channels and the 8-bit alpha transparency mask from the source WebP, producing a genuine 32-bit RGBA PNG. Logos, icons, and sticker graphics will remain completely transparent with no black or white background artifacts.
Are my WebP photos or designs uploaded to any server?
No. All image parsing, rendering, and PNG encoding take place 100% inside your web browser sandbox using hardware-accelerated HTML5 Canvas APIs. Your images never leave your local device, ensuring total privacy, zero data retention, and instant conversion speeds even without high-speed internet.
Why is the resulting PNG file size larger than the original WebP?
WebP utilizes modern predictive encoding and lossy compression designed specifically to compress image files into very lightweight payloads for web browsers. PNG, on the other hand, is a lossless raster format that prioritizes absolute pixel accuracy and universal compatibility over aggressive file size reduction. An increase in file size is normal when converting from WebP to PNG.
Can I convert multiple WebP files at once?
Yes. You can drag and drop dozens of WebP images simultaneously. Toolhast converts them in parallel using browser threads and allows you to download them individually or as a single neatly organized ZIP file with one click.
Is there any limit on file sizes or daily conversions?
No. Because Toolhast runs entirely on your own device rather than costly cloud servers, there are no artificial file size caps, daily limits, paywalls, or forced account registrations.
