Frequently asked questions
Are my photos uploaded?
No. The image codecs run as WebAssembly in your browser. You can switch off Wi-Fi after the page loads and it still works.
Is there a file limit?
No. Convert as many images as you like, as large as your device can handle.
Will WEBP look the same as PNG?
WEBP is a lossy format; at the default quality differences are invisible at normal viewing sizes.
