Examples

1. Reduce Podcast File Size for Upload

Podcaster
Background
A podcaster records episodes in high-quality MP3 format, resulting in large files with embedded artwork and metadata tags.
Problem
The files exceed size limits for quick upload to the podcast hosting service, causing delays in publishing.
How to Use
Upload the MP3 file, check 'Remove all metadata' and 'Remove embedded artwork', then process and download the compressed file.
Example Config
Options set: removeMetadata: true, removeArtwork: true
Outcome
File size is reduced by removing unnecessary data, enabling faster uploads without compromising audio quality.

2. Optimize Music Files for Mobile Storage

Background
A user has a collection of music files with large embedded album art that consumes extra storage on their smartphone.
Problem

Outcome
Files are compressed, freeing up storage space while preserving the audio tracks for playback.
