Minibyte

iPhone · Photos & video

From gigabyte to Minibyte.

Minibyte makes your photo library smaller without making it poorer. Videos and Live Photos shrink in place and stay on the right day and the right spot on the map. Nothing is deleted until its replacement is saved.

  • Pay once, no daily limit
  • Keeps date and place
  • No upload

Pay once. That's the whole price.

Minibyte tells you what a job will cost before it runs, and never deletes an original it hasn't replaced

Duplicates

Nine goes at one photo.

Exact copies, and the near-copies from the same few seconds. Minibyte ranks the frames on sharpness and on whether the faces came out, then recommends one — and you can overrule it on any frame.

Metadata

Your photos keep their dates.

Most compressors hand back a file stamped with today. Minibyte carries the original metadata across, so a photo you shrank in August is still a photo from June.

Prefer to drop the location? One switch, and the capture date stays.

A Remove location switch, labelled: keeps the date, drops where it was taken.

Shrink to share

And when one file has to get smaller.

What it does

Seven tools, one photo library.

Each one does a single job, and tells you the cost before it runs.

Free up space

Scan for what's actually big in your library, then take it category by category or file by file. Nothing is deleted before its replacement is saved.

Find duplicates

Exact copies, and near-copies from the same few minutes. Compared on your iPhone, never uploaded to be compared elsewhere.

Screenshots

Receipts, maps and confirmations, grouped by the month you took them, cleared in one pass.

Live Photos

Keep the picture, drop the three seconds of video attached to it. Month by month, with the recoverable size on each.

Sort by hand

Swipe through the photos no scan can judge, one at a time.

Shrink to share

Too big to email? Pick photos or videos, choose how small, send. Or shrink straight from the Photos share sheet without opening the app.

Convert format

HEIC to JPEG when the other app refuses to open it, and back again. MOV to MP4 for video.

Inside the app

Six screens, nothing staged.

Safety

It never deletes what it hasn't replaced.

  • An original goes only after the smaller copy is confirmed saved. A failure or a skip leaves it alone.
  • Every deletion goes through iOS's own prompt, and stays in Recently Deleted for 30 days.
  • When a re-encode comes out larger — it happens with small files — the original stays and the app says so. It won't report a saving it didn't make.

Nothing leaves your iPhone.

Minibyte has no servers of its own, no third-party SDKs and no advertising. Nothing is uploaded. The one thing that can go online is iOS fetching your own photos from your own iCloud so they can be compared — Wi-Fi only, and you can turn it off.
