Detect & Prevent Duplicate Images

Turn on Prevent Duplicate Uploads in ThumbPress Pro. From then on, every upload is checked against your existing media by content hash and blocked if a byte-identical file already exists - no scans or manual steps.

Yes. Instead of blindly deleting, the merge step first repoints every reference - post content, featured images, WooCommerce galleries, Elementor, ACF, logo and site icon - to the copy you keep, then trashes only the redundant ones.

No. Matching is done on the file content, not the filename - so two genuinely different images are always allowed through, even if they share a name.

No. Detection is exact-match by design: only byte-identical files are grouped. A re-compressed or resized version is a different file, so it is never merged away by mistake.

No. Hashes are generated once in a background queue and then stored, so scans afterwards are simple lookups rather than a fresh pass over your disk.

No. Each upload is hashed as it arrives, so new images are covered by both detection and prevention from the moment they land.

Both. Detection cleans up the duplicates that have already accumulated; prevention stops the library filling back up. Running one without the other leaves half the problem in place.
