Disavow File Merger
A disavow file merger combines two or more disavow files into one clean file. Paste or upload up to five lists, and this free tool removes repeated entries, keeps your comments and gives you a single disavow.txt to download. It also shows exactly which lines were removed and why.

What is a disavow file merger and when should you use it?
Many sites end up with more than one disavow list, for example an older file and a new list from a recent audit. Combining them by hand makes it easy to repeat a domain or lose one. This tool reads every list, normalises each entry and writes one file in the format Google's disavow tool expects. Nothing is dropped silently: every removed or skipped line appears in the changes table. Check the result with the Disavow File Validator. Before merging, ensure each source file is properly formatted using the Disavow File Validator or clean irregular directives with the Disavow File Cleaner. To create new disavow directives from raw exports, use the Disavow File Generator or identify unnatural link patterns with the Toxic Backlink Checker. To audit additions between monthly submissions, run Compare Disavow Files, or export your consolidated rules to a spreadsheet using Disavow File to CSV. For link dataset preparation, clean Google exports with the Search Console Links CSV Cleaner, eliminate duplicate domains via the Backlink List Deduplicator, isolate hostnames with the URL to Domain Extractor, and group subdomains using the Subdomain to Root Domain utility.
