About Duplicate File Finder
Use Duplicate File Finder when you need a focused result without installing a separate desktop application. Group selected local files by size and SHA-256 content hash without uploading them. The result changes when the source data or selected options change, so it is easy to run a second comparison.
What this tool does
Group selected local files by size and SHA-256 content hash without uploading them.
Practical guidance
Group selected local files by size and SHA-256 content hash without uploading them. The interface provides a focused workflow, clear output and export or copy controls where useful. Review paths and filenames before deleting any original file outside this browser tool.
Privacy and limitations
Processing is designed to run in the visitor browser. Files and entered content are not intentionally stored by this plugin. Review paths and filenames before deleting any original file outside this browser tool.
What the result represents
A result produced from the exact input and settings you choose.
A practical example
One useful scenario is to complete a repeatable browser task and review the result before using it elsewhere. Start with a representative input, inspect the first result, then adjust one setting at a time if you need a different outcome.
- Handling a one-off task with Duplicate File Finder.
- Preparing a reusable result with Duplicate File Finder.
- Checking an output before the next step with Duplicate File Finder.
Before you use the result
- Review the entire result and retain the original input when it matters. Browser, device and third-party limits can affect very large tasks.
- Check the result against the original input before using it in a live or important workflow.
Privacy and processing
Enter only the information required for the result. Browser-based work stays on the device where supported, while public checks use protected, rate-limited site endpoints.
