Content-based detection

Find the duplicates
other apps can't see.

Most cleaners only compare filenames and sizes. True Duplicate Video Cleaner looks inside every clip — sampling frames and matching them by what they actually show.

The difference

Same video. Different file.
Most apps can't tell.

A clip you sent over WhatsApp, re-encoded by your phone, dropped into a backup folder — it looks identical, but every byte is different. Metadata scanners give up here.

Old way · Metadata scan

Compares names, sizes, hashes

If a single byte differs — different codec, different resolution, a re-export — it's flagged as "unique" and left on your phone.

True Duplicate · Content scan

Compares what's actually on screen

Samples frames across each clip, builds a perceptual fingerprint, and matches videos by what you'd see — not by what the file claims to be.

How it works

Four steps. All on your device.

No cloud uploads. No accounts. Your videos never leave your phone.

01
Sample frames across the clip
We pull evenly-spaced frames from the start, middle, and end of every video — capturing what the clip actually shows, not what it's named.
02
Build a perceptual fingerprint
Each frame is reduced to a tiny visual signature that survives compression, resizing, and re-encoding. The fingerprint is what we compare.
03
Match by similarity, not bytes
Fingerprints are compared with a similarity score. Anything above your threshold is grouped — so re-exports and shares get caught, not missed.
04
Group, review, and recover space
Duplicates are clustered with thumbnails side-by-side. Keep the best version, delete the rest, and watch the free space tick up in real time.
True Duplicate Video Cleaner app
Built for your gallery

A scan that finally finishes the job.

Point it at your camera roll, downloads folder, or WhatsApp media — it sweeps through, groups every true duplicate, and shows you exactly how much space is waiting.

FX
Survives re-encoding
Find that WhatsApp-compressed copy of your 4K original — different codec, different bitrate, same clip.
OS
100% on-device
Frames are sampled and fingerprinted locally. Nothing uploads. Nothing leaves your phone.
GB
Recover gigabytes
Most users free up 8–40 GB on the first scan. The savings counter ticks up as you clean.
UX
Review before delete
See every duplicate group side-by-side. Pick the keeper. Nothing is removed without your tap.

Stop hoarding the same clip
in three formats.

Run one scan. See what's really there. Get your storage back in minutes — not a Saturday afternoon.
