PixelServ using Nginx

Hope you know about pixelserv. It is a webserver which will always response 1x1 transparent gif image for all kind of requests. Mainly used in adblocking and proxy environmental.

In this setup I am going to serve 1x1 pixel using nginx server.

Install nginx

sudo apt-get install nginx -y


changing /etc/nginx/nginx.conf as below

user nginx;
worker_processes 4;

error_log  /dev/stdout;
pid        /var/run/nginx.pid;

events { worker_connections 1024; }

http {

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

      access_log  /dev/stdout;
      sendfile        on;
      keepalive_timeout  65;

      server {
        listen 80 default_server;
        listen [::]:80 default_server ipv6only=on;

        # Make site accessible from http://localhost/
        server_name _;

        location / {


sudo service nginx restart
curl http://localhost/

You will get binary GIF blob in terminal.
