Image Compressor Info

This image compressor is a fast, privacy first image compressor app that uses WebAssembly (wasm) and modern codecs to give near native compression speeds directly in your browser. This beats other sites that uses old JS based compression. By using local client side processing, this image compressor bypasses traditional upload limits and data privacy concerns while providing a highly customizable toolkit (image resizing, color reduction, lossless options, batch file renaming and more).

Website design inspired by Gleam

Compression Queue

The compressor gives you unlimited image compression queue and supports processing 10+ images all at once (customizable too)

Self Hosting

You can host this application yourself using Docker. This method is so the app runs in a consistent environment using a ready Nginx server. If you want your project to be seen by everyone, you need to have a domain name that points to your local machine, and then proxy it to port of this machine, you can use something like Nginx.

Prerequisites

• Docker installed on your system.

Docker CLI

1. Build the image: Navigate to the project root and run:

docker build -t image-compressor .

1. Run the container:

docker run -d -p 8080:80 image-compressor

The app will now be at http://localhost:8080.

Configuration Notes

• Port Mapping: You can change the port by modifying the first number in the port mapping (ex: -p 3000:80 will serve app on port 3000).
• Routing: The included Nginx configuration handles Single Page Application (SPA) routing, so refreshing the page on sub routes will work correctly.
• Updates: To update your self hosted instance, pull the latest code from the repository and rebuild the image using the build command above.

If you find any issues during the setup process, please feel free to open an issue in the repository.
