# imgbot/Imgbot

An Azure Function solution to crawl through all of your image files in GitHub and losslessly compress them. This will make the file size go down, but leave the dimensions and quality untouched. Once it's done, ImgBot will open a pull request for you to review and merge. help@imgbot.net

## What it is
Imgbot is a GitHub App backed by an Azure Functions solution that crawls a repository's image files and losslessly compresses them, then opens a pull request with the optimized images. It supports configuration via a .imgbotconfig file for schedules, ignored files, aggressive compression, and custom PR text.

## Use cases
- automatically compress images in my github repository
- optimize images via pull requests without changing quality
- reduce repo image sizes to speed up web page loads
- schedule recurring image optimization PRs
- ignore certain images or folders from compression
- compress images in a github wiki

## When to choose
- you host code on GitHub and want hands-off, ongoing image optimization
- you want lossless compression that preserves dimensions and quality
- you prefer a pull-request-based review workflow
- you want a free tool for open source projects

## When to avoid
- your repositories are not hosted on GitHub
- you need on-demand or local (non-cloud) image compression
- you need resizing or format conversion rather than compression
- you require fully self-hosted automation without a third-party GitHub App
