FAQ — PNG to WebP Converter
Short answers to common questions. Click a question to reveal a concise answer.
Simply upload your PNG images (you can select multiple), and they will be automatically converted to WebP format in your browser. Then download individual files or use "DOWNLOAD ALL" for a ZIP containing all converted images. The entire process happens client-side for maximum privacy.
No. All conversion happens in your browser using JavaScript. Your image never leaves your device unless you explicitly share it elsewhere.
Images larger than 10MB are automatically skipped to ensure optimal browser performance. For best results, we recommend keeping images under 10MB. Very large images (over 4000x4000 pixels) may also cause performance issues or fail to convert due to browser canvas limitations. The conversion happens entirely in your browser's memory.
While there's no strict dimension limit in our code, very large images (typically over 4000x4000 pixels or 16+ megapixels) may fail to convert due to browser memory limitations. Most modern browsers can handle images up to about 4096x4096 pixels, but performance may be slow for extremely large images. If you have very high-resolution images, consider resizing them first or using a desktop image editor.
WebP is a modern format that offers excellent compression while maintaining high quality. Converting PNG to WebP typically results in significantly smaller file sizes with minimal quality loss, especially for images with gradients or complex details. The conversion preserves transparency and uses browser-optimized settings for best results.
Yes! You can upload and convert multiple PNG images at once. Each image is processed individually and you can download them separately or use "DOWNLOAD ALL" to get a ZIP file with all converted WebP files.
After converting multiple images, click the "DOWNLOAD ALL" button that appears at the bottom. This creates a ZIP file containing all your converted WebP images, making it easy to download everything at once.
This converter specifically converts PNG images to WebP format. Other image formats like JPG, GIF, or WebP conversions to other formats are not supported here. Please upload PNG files for PNG-to-WebP conversions.
Both PNG and WebP support transparency. When converting PNG to WebP, transparency is fully preserved. If your PNG image has transparent areas, they will remain transparent in the WebP output.
No, this converter uses browser-optimized default settings for WebP conversion. The quality is set to maintain excellent visual quality while achieving good compression. If you need custom quality settings, use a desktop image editor or command-line tools.
No, EXIF metadata is not retained during conversion. The browser's canvas API used for conversion does not preserve metadata like EXIF, GPS coordinates, or other embedded information. This is actually beneficial for privacy as it removes potentially sensitive location or camera data.
The converter works best in modern browsers: Chrome, Firefox, Edge, and Safari. Older browsers or mobile browsers may have limitations with memory or performance during conversion.
The conversion itself happens entirely in your browser without any server communication. However, you need an internet connection to initially load the webpage and JavaScript files. Once loaded, you could theoretically use it offline for subsequent conversions if your browser has cached the assets.
If you get an error, try a smaller file or a different browser. If the image is corrupted, re-export or try opening the file in an image editor first. Very large images (over 4000x4000 pixels) may also fail due to browser memory limits. You can contact support for persistent issues.
