Find duplicate photos online without uploading them
Most online duplicate finders ask you to upload thousands of photos first. DupShelf runs in your browser and reads files from your computer, so your gallery never leaves your device.
How DupShelf finds duplicates online (locally)
Open the workbench, grant folder access, and we hash each image with SHA-256. Files with the same hash are exact duplicates, even when names or folders differ.
Best for
- Laptop and desktop libraries in Chrome or Edge
- WhatsApp and download folders with renamed copies
- Backup drives before you sync to the cloud
Questions
- Is DupShelf really online if files stay local?
- The app loads from the web, but scanning happens in your browser tab on your machine. No photo bytes are sent to our servers.
- Do I need to create an account?
- No account, no subscription. Open the tool and scan when you need it.
