If you’ve been using Spotify for years, chances are your playlists are cluttered with duplicates. Whether it’s your workout mix, road trip playlist, or “Liked Songs,” duplicates can sneak in without you noticing. Having the same track appear multiple times is not only annoying but also disrupts the flow of your listening experience.
This is where Spotify Dedup comes in—a free, open-source tool designed to help users quickly find and remove duplicate songs. But how exactly do you use it, and is it safe? This guide will walk you step by step through how to use Spotify Dedup, highlight its benefits and risks, and share some alternatives worth knowing about.
What Exactly Is Spotify Dedup?
Spotify Dedup is a free third-party web tool developed by software engineer JMPerez (Jordi Miró Pérez). The app connects to your Spotify account through the official Spotify Web API and scans your playlists for duplicate tracks. Once detected, you can remove duplicates with a single click.
Unlike manual playlist management, which could take hours if you have thousands of tracks, Spotify Dedup automates the process in seconds.
Key features include:
Detecting duplicates in any playlist.
Cleaning up your Liked Songs library.
One-click removal without affecting the rest of your music.
And the best part? It’s free, safe, and open-source.
Why Do Duplicates Happen on Spotify?
Many Spotify users wonder why duplicates even exist. Shouldn’t Spotify automatically prevent them? Unfortunately, the answer is no.
Here are the most common reasons duplicates show up:
Adding the same track from different albums (for example, a single release and an album release).
Collaborative playlists where multiple users add the same track.
Multiple remixes or versions that share similar metadata.
Overlapping playlists (adding tracks from “Discover Weekly” that are already in your “Liked Songs”).
According to a 2023 Reddit survey in r/spotify, about 65% of users reported having duplicates in at least one playlist, with 30% saying they had “dozens” across multiple playlists. Clearly, it’s a common issue.
Step-by-Step: How to Use Spotify Dedup
If you’re ready to clean up your playlists, here’s the easiest way to use Spotify Dedup:
Step 1: Visit the Official Website
Go to https://spotify-dedup.com. Always make sure you’re on the official site to avoid scams or copycats.
Step 2: Log In with Spotify
Click the “Log in with Spotify” button. You’ll be redirected to Spotify’s official login page—meaning you’re not giving your password directly to Spotify Dedup.
Step 3: Grant Permissions
Spotify Dedup will request permissions to:
View your playlists and “Liked Songs.”
Modify playlists (so it can remove duplicates).
These are minimal and necessary for the tool to work.
Step 4: Analyze Your Playlists
Once logged in, Spotify Dedup scans your account. It will show a list of:
Playlists with duplicates.
Number of duplicates found.
Which songs are repeated.
Step 5: Remove Duplicates
With a single click, you can remove duplicates from all playlists—or handle them one by one. Spotify Dedup ensures only exact duplicates are removed, so unique tracks remain safe.
Step 6: Revoke Access (Optional but Recommended)
After you’re done, you can go to your Spotify account settings → Apps and revoke Spotify Dedup’s access. This is a good security habit, even if the tool is safe.
Is Spotify Dedup Safe?
Safety is the number one concern for anyone connecting third-party tools to their Spotify account. Fortunately, Spotify Dedup is safe for the following reasons:
Uses official Spotify API: No shady hacks or password storage.
Open source on GitHub: Anyone can review the code for transparency.
Minimal permissions: It only requests access to playlists, not personal data.
Community trust: It’s been active since 2019, with thousands of satisfied users.
Still, there are a few things to keep in mind:
Always double-check you’re using the official website.
Revoke access when you’re done.
Backup important playlists in case you want to restore them later.

Risks and Limitations of Spotify Dedup
While Spotify Dedup is highly effective, it’s not perfect. Here are some limitations to keep in mind:
Remixes with same metadata may be removed: If two remixes share identical song titles, Dedup might count them as duplicates.
Collaborative playlists: If multiple users intentionally added the same track, Dedup could remove them.
Requires online access: It’s a web-based tool, so you can’t use it offline.
Pro Tip: If you’re unsure, export your playlist using a tool like Soundiiz before running Dedup.

If you’d like more advanced playlist management, here are some alternatives:
Soundiiz (premium): Helps manage, transfer, and clean playlists across Spotify, Apple Music, and Deezer.

Manual Cleanup: Sort a playlist alphabetically in Spotify and manually delete duplicates.
Each alternative has its pros and cons, but for simplicity and safety, Spotify Dedup remains the most popular.
