Questions
What is a JFIF file?
JFIF is a JPEG image with a different file extension. Converting it to .jpg makes it accepted by sites and apps that only recognise the .jpg extension.
Are my images uploaded?
No. Conversion happens in your browser with the Canvas API, so your images never leave your device.
Does resizing keep the aspect ratio?
Yes. Images wider than the maximum width are scaled down proportionally; smaller images are left at their size.
