Frequently Asked Questions
Is my image uploaded to a server?
No. This tool uses the browser's Canvas API entirely client-side. Your image data never leaves your device and is not transmitted to any server.
What quality setting should I use?
85% (the default) is the recommended balance between file size and visual quality for most web images. For photographs, 80–90% is typical. For logos or icons, 90–100% preserves crisp edges.
Will WEBP work on all browsers?
Yes. As of 2024, all major browsers — Chrome, Firefox, Safari (since version 14), Edge, and Opera — support WEBP. Global support is above 96%.
Does this tool work on mobile?
Yes. The tool is fully responsive and works on Android Chrome and iOS Safari (iOS 14+). File size and conversion speed depend on your device's hardware.
What is the maximum file size I can convert?
There is no hard server-side limit since conversion is client-side, but very large files (above ~20 MB) may be slow depending on your device RAM and CPU. For large batch conversions, we recommend a desktop browser.
