Reclaim gigabytes.
Lose nothing.

Phone cameras and screen recorders encode in a hurry and leave files three to ten times larger than they need to be. Hevity squeezes that waste back out, verified frame by frame, entirely on your device.

The proof is in the pixels

Same video. A fraction of the size.

Hevity re-encodes with the same hardware encoder Apple uses, then checks the result frame by frame against your original. You drag a slider and see for yourself before anything is replaced.

Both halves are the same frame. If Hevity cannot prove a result is visually identical, it fails the video and leaves your original untouched.
What it does

Built to earn your trust, byte by byte

Reclaim

Squeeze out the waste

Re-encodes bloated videos with your device's native encoder, cutting file sizes by up to 90 percent with no visible loss.

Verified

Quality you can see

Every result is checked frame by frame with a real similarity score and a before and after slider, before you approve it.

Protected

Originals never at risk

Nothing is replaced without your approval. Approved swaps move the original to Recently Deleted, recoverable for 30 days. HDR stays HDR, ProRes is protected by default.

Where it works

Your whole library, and every folder

Photos

Your Photos library

Scan to surface the biggest, most bloated videos and reclaim them in place. Approved originals move to Recently Deleted, so nothing is ever a one way door.

Files and folders

Any folder on your Mac

Point Hevity at Downloads, Movies, or a pile of screen recordings. It measures the bitrate of every clip, squeezes what is worth squeezing, and shows a verified compare before any file is replaced.

How it works

Scan, verify, approve

  1. Scan your library or any folderHevity reads each video's real bitrate on your local hardware and shows exactly how much space is recoverable. Nothing is touched during a scan.
  2. Compress and verifySelected videos are re-encoded into temporary copies and checked frame by frame against the original. Results wait for you. Nothing is replaced yet.
  3. Compare and approveDrag the before and after slider. When you approve, the original moves safely aside and your storage comes back.
Prepare for sharing. Hevity also makes messenger ready copies sized for WhatsApp and Instagram, tuned so their own compression has nothing left to ruin. The original is always left untouched, and the shared copy carries no location data.
Private by design

Your videos never leave your device

No sign up, no cloud uploads, no analytics, no tracking, no third party SDKs. The only thing Hevity stores is a local counter of how much space you have saved, and deleting the app deletes it. Apple handles every payment, so nothing card related ever touches the app.
