What is WebP format and why should I use it?

WebP is a modern image format developed by Google that provides superior compression compared to JPEG and PNG. It typically results in 25-35% smaller file sizes while maintaining the same visual quality, making it ideal for web performance optimization, faster page loads, and improved Core Web Vitals scores.

Is WebpCraft safe to use with sensitive images?

Yes, WebpCraft is completely safe for sensitive images. All processing happens locally in your browser using JavaScript and Canvas API. Your images are never uploaded to any server, ensuring complete privacy and security. The conversion is 100% client-side.

How many images can I convert at once?

There is no limit to the number of images you can convert. WebpCraft supports unlimited bulk conversion with queue-based processing. You can convert hundreds or thousands of images in a single session, limited only by your device's memory and processing power.

Does WebpCraft work offline?

Yes, after the initial page load, WebpCraft can work completely offline. All conversion happens in your browser, so you don't need an internet connection to convert images. This makes it perfect for working with sensitive data or in environments with limited connectivity.

What image formats does WebpCraft support?

WebpCraft currently supports converting JPG/JPEG, PNG, and GIF images to WebP format. Both static images and animated GIFs are supported. The tool maintains transparency for PNG images and animation for GIF files.

Is there a file size limit for conversion?

No, WebpCraft has no file size limits. Since all processing happens locally in your browser, you can convert images of any size. The only limitation is your device's available memory and processing capability.

Can I control the quality of converted images?

Yes, WebpCraft provides a quality slider ranging from 1-100%. Lower values create smaller files with reduced quality, while higher values maintain better quality at larger file sizes. You can also enable resizing to reduce image dimensions for additional size savings.

Is WebpCraft really free?

Yes, WebpCraft is completely free and open source. There are no hidden costs, subscriptions, or premium features. All functionality is available to everyone at no charge. The project is licensed under Apache-2.0 and available on GitHub.

How do I download converted images?

After conversion, you can download images individually by clicking the download button for each image, or download all converted images at once as a convenient ZIP archive. The bulk converter automatically organizes files for easy batch downloading.

Does WebpCraft collect or store my images?

No, WebpCraft does not collect, store, or transmit your images anywhere. All processing happens entirely in your browser. We don't have servers to receive images, and we don't use analytics that track your files. Your privacy is guaranteed by design.

How to Convert PNG to WebP

Convert your PNG images to WebP format with transparency preservation. WebP provides better compression than PNG while maintaining alpha channel support.

Upload Your PNG Files

Click "Choose Files" or drag and drop your PNG images onto the converter. Multiple files can be processed simultaneously.

Configure Quality

Adjust the quality slider to your preference. For PNG images with transparency, we recommend 90-95% quality to preserve fine details and smooth edges.

Set Dimensions (Optional)

You can resize your PNG images during conversion. Use the width and height inputs or select a preset size. The aspect ratio lock prevents distortion.

Convert & Preview

Click "Convert to WebP" to process your images. The converter preserves transparency automatically. Review the side-by-side comparison to verify quality.

Download WebP Files

Save your converted WebP files by clicking the download button. The WebP format typically reduces PNG file sizes by 25-35% while maintaining transparency.

💡 Transparency Handling

WebP fully supports transparency (alpha channel) just like PNG. Your transparent backgrounds and semi-transparent pixels are preserved during conversion.

This makes WebP an excellent replacement for PNG images, especially for web graphics, logos, and UI elements that require transparency.

🔒 Privacy Guaranteed

All PNG to WebP conversion happens locally in your browser. Your images are never uploaded to any server, ensuring complete privacy and security.
