 ## Features
 
-- **Local files uploads**: Upload files as multipart/form-data or as a simple byte stream and store them to a local directory.
+- **Local file storage**: Upload files as multipart/form-data or as a simple byte stream and store them to a local directory.
 - **Automatic GIF to video conversion**: Convert GIFs to videos because GIFs suck, slow down web pages, and don't support hardware acceleration.
-- **Image and video conversion and optimization**: Transcode and optimize media files on upload or on-the-fly.
-- **Dynamic resizing**: Easily resize images in real-time by modifying the URL, which helps in reducing bandwidth and storage space on devices.
+- **Image and video transcoding and quality optimization**: Transcode and optimize media files on upload or on-the-fly. If you are doing a public storage, you can pre-set your own quality settings to save disk space and bandwidth.
+- **Dynamic resizing**: Easily resize images in real-time just by modifying original URL. You can automatically generate image/video previews on demand without uploading multiple versions of the file.
 - **High performance**: Pepic uses native libraries like `ffmpeg` and `vips` for video and image processing to ensure high performance and fast processing times.
 - **Local and containerized environments**: Designed to run smoothly in both local environments and within Docker containers, making it versatile for development and deployment.
-- **Custom configuration**: Flexible configuration options through `[config.yml](./etc/pepic/config.yml)`, allowing adjustments to image size, quality, automatic conversion, templates, etc.

 Works only if `live_resize` option is set to `true`. If `live_resize=false` — it returns the original version. Same for video transcoding (where it's off by default).
 
-> ⚠️ **Note:** Each resized version is saved as a separate file with its SHA hash. When the same version of the file is requested again, Pepic just read it from disk and does not waste CPU time resizing it again. However, if you have many resized versions stored, this can eat quite a bit of disk space. Be careful.
