Frequently Asked Questions
When managing large SEO projects, sitemaps, or backlink profiles, it is easy to accidentally include the same URL multiple times. Deduplicating your lists prevents wasted crawl budget, avoids redundant outreach, and ensures your data analysis is accurate.
Currently, the tool performs a strict string-based deduplication. This means it only removes exact matches. If you have http://site.com and https://site.com, they are technically different strings and will both remain. We recommend standardizing your protocols before checking.
The tool can comfortably handle lists of up to 10,000+ links depending on your computer's RAM. Since the processing happens entirely in your browser, extremely large files (millions of rows) may cause your tab to slow down or freeze.
Yes. The tool treats every line as a unique string. Whether it is a full URL, a subdomain, or a simple URI path like /blog-post-1, it will find and remove any exact repetitions of that line.
No. We prioritize your data security. All link analysis and removal happen using client-side JavaScript within your own browser. Your lists are never uploaded, stored, or viewed by anyone at Toolszu.
You can use the "Download .txt" button to save the unique links as a standard text file, or simply click "Copy List" to move them directly into an Excel sheet, Google Doc, or SEO tool of your choice.
