Spotify MP3 Converter

About This Tool

This tool provides a compliant workflow to convert locally owned audio assets into MP3s while associating them with Spotify playlist data. It accepts either native audio files (WAV/FLAC/AAC/OGG) or a Spotify export file (CSV/JSON) containing track identifiers and metadata. It then encodes each source to MP3 at a chosen bitrate and sample rate, and writes ID3 tags from the available metadata. The result is a set of MP3 files plus a portable playlist (M3U8 or CSV) that references the converted assets. Importantly, the tool does not download or stream Spotify content and does not bypass DRM; it operates only on legally owned files and metadata supplied by the user. This makes it suitable for personal music archiving, podcast workflows with licensed material, or museum/library digitization projects that require consistent metadata and format compatibility. The core value lies in reducing manual tagging, preserving metadata integrity, and enabling cross-device portability while remaining within licensing constraints. Core features include multi-input handling, metadata mapping from Spotify exports to ID3 fields, batch processing, and optional playlist export, with clear reporting for any missing assets or encoding failures. Use cases include migrating a local collection to MP3 with accurate artist/album data, exporting a Spotify playlist's track list for cataloging, and preparing assets for distribution under licensed terms.
