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 PNG look the same as JPG?
PNG is lossless, so yes, pixel for pixel.
