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.

WebpCraft Privacy Policy

Your privacy is our top priority. This page explains how we handle your data (or rather, how we don't).

The Short Version

We don't collect, store, or transmit any of your images or personal data. All image conversion happens directly in your browser. We have no servers processing your images, no databases storing your files, and no tracking of any kind.

How Image Conversion Works

When you select an image to convert, it is loaded into your browser's memory. The conversion happens entirely within your browser using JavaScript and the HTML5 Canvas API.

Your images are never uploaded to our servers or any third-party servers. The conversion process is completely client-side, meaning everything happens on your device.

Once you close the browser tab, all images are immediately removed from your browser's memory. We have no way to access your images because they never leave your device.

No Data Collection

We do not collect any personal information, usage data, or analytics. This includes:

No image files or file metadata
No IP addresses
No browser fingerprinting
No cookies (except essential ones for the website to function)
No analytics or tracking scripts
No third-party advertising or tracking
No user accounts or registration

Open Source Technology

This converter uses standard web technologies that are open and transparent:

FileReader API - Reads files from your device
Canvas API - Processes and converts images
Blob API - Creates downloadable files

All of these technologies run entirely in your browser without any server communication after the initial page load.

Works Offline

After the initial page load, you can disconnect from the internet and the converter will continue to work. This is proof that no data is being transmitted to any servers during the conversion process.

Third-Party Services

We do not use any third-party services for image processing, analytics, or advertising. The website is hosted on a static hosting platform and serves only static HTML, CSS, and JavaScript files.

There are no third-party scripts that could track you or access your images.

Your Rights

Since we don't collect any data about you, there's no data to access, modify, or delete. You maintain complete control over your images at all times.

You can verify that no data is being transmitted by using your browser's developer tools to monitor network activity during conversion.

Updates to This Policy

If we ever change how we handle data (which would be a fundamental change to how this tool works), we will update this privacy policy and clearly announce the changes.

Questions?

If you have any questions about this privacy policy or how the converter works, please check our FAQ page for detailed technical information.

✅ Privacy Guarantee

We guarantee that your images never leave your device. This is not just a promise—it's how the technology works. Client-side processing means complete privacy by design, not by policy.
