If you are a long-time Spotify user, chances are your playlists are filled with duplicate songs. You add the same track multiple times across different playlists, or your carefully curated “Favorites” end up bloated with repeats. This is where Spotify Dedup comes in—a free web tool that automatically finds and removes duplicate songs from your playlists and your “Liked Songs.”
But the big question many users ask is: Is Spotify Dedup safe? In this article, we’ll break down how Spotify Dedup works, its safety, why people use it, possible risks, and alternatives you can consider in 2025.
What Is Spotify Dedup?
Spotify Dedup is a third-party web application created by JMPerez (Jordi Miró Pérez), a software engineer who has built several open-source Spotify tools. It connects directly to your Spotify account through Spotify’s official Web API and scans your playlists for duplicate tracks.
Once connected, Spotify Dedup shows you:
Which playlists contain duplicates.
How many repeats you have in “Liked Songs.”
Options to remove duplicates with one click.
The tool is widely praised for its simplicity. Unlike manually scanning through hundreds of tracks, Spotify Dedup does the job in seconds.
How Spotify Dedup Works Behind the Scenes
To understand if Spotify Dedup is safe, it’s important to know how it works technically:
OAuth Authorization
Spotify Dedup never asks for your password. Instead, it uses Spotify’s OAuth login system. This means you log in through Spotify’s own secure page, and Spotify provides the tool with a temporary access token.Permissions Granted
The tool only requests the following permissions:Access to your playlists.
Ability to modify playlists (for removing duplicates).
It does not ask for email access, payment details, or sensitive data unrelated to music.Data Handling
According to the developer, Spotify Dedup does not store your login details or music library permanently. The processing happens in real time when you use the tool.Open Source
The project is open source and available on GitHub, meaning anyone can review the code for transparency. This is one of the strongest indicators of safety compared to closed-source apps.
Is Spotify Dedup Safe?
Based on technical details and user reports, Spotify Dedup is safe to use for the vast majority of users. Here’s why:
Uses official Spotify API: It doesn’t bypass Spotify’s systems or use shady hacks.
No password collection: All authentication happens via Spotify’s secure login.
Community trust: The tool has been around since 2019 and is recommended on forums like Reddit’s r/spotify.
Open source code: Users and developers can inspect the code to ensure there are no hidden risks.
That being said, it’s important to keep in mind the risks of any third-party tool:
If the developer’s website were compromised, attackers could theoretically misuse permissions.
You are granting playlist modification rights, so always make sure you’re on the official Spotify Dedup site (https://spotify-dedup.com).
Spotify itself warns that third-party apps can potentially access your data, so revoking access when you’re not actively using it is a good practice.
Real Data: How Many People Use Spotify Dedup?
Spotify Dedup doesn’t publicly release exact user numbers, but as of 2025:
The project has over 2,500 stars on GitHub, indicating strong developer trust.
On Reddit and other music forums, threads discussing Spotify Dedup often receive hundreds of upvotes.
Based on web traffic analytics from SimilarWeb, the site receives around 50,000–70,000 monthly visits.
Clearly, it has built a solid reputation over several years.
Why Use Spotify Dedup?
Here are the most common reasons Spotify users turn to Dedup:
Large Playlists Get Messy
If you’ve been using Spotify for 5–10 years, chances are your playlists have thousands of tracks. It’s nearly impossible to track duplicates manually.Improves Listening Experience
Nobody wants the same song popping up three times during a road trip playlist.Optimizes Storage
Offline downloads take up space on your phone. Removing duplicates reduces redundant storage.Works Across “Liked Songs”
Spotify doesn’t automatically prevent you from liking the same track multiple times in different contexts. Dedup cleans that up.
Potential Risks of Spotify Dedup
While Spotify Dedup is generally safe, it’s worth being aware of potential risks:
Third-Party Access: You are still granting an external app access to your Spotify account.
Account Revocation: In rare cases, Spotify has revoked access to accounts that use unauthorized third-party tools. Dedup, however, uses official APIs, so the risk is low.
Accidental Deletions: If you’re not careful, you could remove duplicates you wanted to keep (such as different remixes with identical metadata).
Pro Tip: Always double-check the summary before confirming deletions.
How to Use Spotify Dedup Safely
If you decide to use Spotify Dedup, here’s how to minimize risks:
Only use the official website: https://spotify-dedup.com
Log in through Spotify’s official OAuth popup—never enter your credentials directly into the tool.
After cleaning your playlists, go to your Spotify account settings → Apps and revoke Spotify Dedup’s access until you need it again.
Save a backup copy of important playlists before running Dedup, in case you want to restore them later.
