=== How To Upload ===
You can upload files to this site via a simple HTTP POST, e.g. using curl:
curl -F "file=@/path/to/your/file.jpg" https://x0.at/

Or if you want to pipe to curl *and* have a file extension, add a "filename":
echo "hello" | curl -F "file=@-;filename=.txt" https://x0.at/

On Windows, you can use ShareX and import this custom uploader.
On Android, you can use an app called Hupl with this uploader.


Or simply choose a file and click "Upload" below:
(Hint: If you're lucky, your browser may support drag-and-drop onto the file 
selection input.)


 === File Sizes etc. ===
The maximum allowed file size is 1024 MiB.

Files are kept for a minimum of 10, and a maximum of 360 Days.

How long a file is kept, depends on its size. Larger files are deleted earlier 
than small ones. This relation is non-linear and skewed in favour of small 
files.

The exact formula for determining the maximum age for a file is:

MIN_AGE + (MAX_AGE - MIN_AGE) * (1-(FILE_SIZE/MAX_SIZE))^2
