=== 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/

To use a longer file ID (up to 24 characters), add -F id_length=<number>

If you want to upload using netcat:
echo "hello" | nc x0.at 9999

Or if you want to upload via SSH (yes, really):
echo "hello" | ssh 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.)

The maximum allowed file size is 100 MiB.

Files are kept for a minimum of 3, and a maximum of 100 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 

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