FAQ
Are my images uploaded?
No. Decoding and encoding happen in this browser, and the converted files are created on your device.
Which format should I pick?
WebP and AVIF give much smaller files than JPG at similar quality and work in all modern browsers. Use PNG for screenshots or images that need sharp edges and transparency, and JPG for the widest compatibility.
What happens to transparency and metadata?
PNG, WebP and AVIF keep transparency. JPG has no transparency, so transparent areas are filled with the background color you choose. Metadata such as EXIF location is removed, and photos are rotated according to their EXIF orientation.
