Choose a folder and find the files that are exactly the same, even when their names differ. See how much space the copies take and export the list.
Your files never leave your device
Files are first grouped by size, then their content is compared with a SHA-256 fingerprint. Two files are duplicates only if every byte is the same, so “photo.jpg” and “photo copy (1).jpg” are found, while two different files with the same name are not.
The tool never deletes or changes your files. Use the report to decide what to remove yourself. Files over 512 MB are compared by samples and marked “probable” to keep the check fast.
Yes. Only the content matters.
No. It only shows and exports the duplicates; deleting stays your decision.
Only files with the same size are read, so it is usually quick. Large folders of videos take longer because every candidate is read completely.
For files over 512 MB, three 8 MB parts and the size are compared instead of the whole file. Matching samples almost always mean identical files.
Yes. Set a minimum size in KB.
No. The files are read and compared in your browser on your device.
