Frequently asked questions
Does AVIF conversion upload my image?
No. AVIF is encoded locally using WebAssembly. Your browser downloads the encoder code, but your selected image is processed on your device.
Is a new format guaranteed to be smaller?
No. The result depends on content, quality, and the original compression. Compare the actual file sizes and inspect the image, particularly text and fine edges, before replacing an original.
Are my files uploaded or stored?
The conversion happens in your browser. Keep the original files and save your downloads before closing the page. Learn how local processing protects your images.
