Privacy details

Duplicate file photo finder processes your input in this browser. Inputs and results are excluded from analytics. Recent tools save tool names, visit counts and last-visit times. Saved tools store only their names. Draft saving is optional and stays on this device; delete saved text with the draft controls. Loading text from a URL is optional and contacts that server; its URL and your IP address are visible to the server. An optional “Use in” action keeps a handoff in this tab. The next tool removes it on arrival and ignores it if more than a minute has passed.

Copy link includes the inputs you choose to share in the address. Anyone with that link can reopen them. Files and generated results are excluded. Password and key tools share settings only.

Reset reloads the tool with its starting values and releases open files and device controls. Saved drafts stay on this device until you delete them.

Links include your inputs and settings. Anyone with the link can see them, so leave out private text. Files and generated results are left out; random draws run again.

Using the duplicate file photo finder

Files with the same length and SHA-256 digest are grouped together. Names and dates do not decide whether files match. The result lists duplicate groups so you can review your own copies.

A worked example

The example files “copy-a.txt” and “copy-b.txt” both contain the word octopus, so they appear in one duplicate group.

Before you use the result

This finds identical files, not visually similar photos. Different metadata or recompression changes the file bytes. Nothing is deleted. Choose up to 100 files totaling no more than 100 MB.
