Frequently asked questions
Is my image uploaded to a server?
No. All conversion happens in your browser using WebAssembly (WASM). Your image never leaves your device.
Which format should I use for web images?
WebP is the best choice for most web images — it offers smaller file sizes than JPEG and PNG with comparable quality, and is supported by all modern browsers. AVIF is newer and even more efficient but has slightly less browser support.
