Drop. Check. Keep.
Have a look.
See the new size in the row and compare the copy with its original before you keep it.
Keep the lighter copy.
Save puts it next to the original, named like photo-smally. Smally never replaces your original or any file already there.
What Smally makes from an iPhone video
A copy for sharing: H.264 video made with x264, up to 1080p and 30 frames a second, so a 4K iPhone clip becomes a 1080p copy. A clip recorded with Slo-mo is skipped, because the copy would play at normal speed. The HDR an iPhone records (HLG) is converted so the colours look right on any screen.
A copy is kept only when it is at least 10% lighter than the original. Videos can be up to 8 GB, and the list holds up to 50 files at a time.
Before you send it
- Smally promises no size: the copy is made at a constant quality, so a longer clip stays heavier. Check the size in the row, because WhatsApp, Slack, iMessage and your mail provider set their own limits.
- Video copies are made for sharing, so they can look a little different from the original. Play the video next to its copy, or step through it a frame at a time, before you rely on one.
- Save puts the copy next to the original. Smally never replaces your video.
What it skips
- Some videos are skipped, with the reason: protected files, slow motion, HDR10 and Dolby Vision profile 5, other wide-colour video, and clips with more than one video track.
Why not in the browser
Video needs the app, on your Mac. The browser version at /compress/ is for JPEG, PNG and WebP images, and a video dropped there is never uploaded.

Questions
Does Smally upload my iPhone video?

Can it shrink a 4K iPhone video?
Yes. The copy is H.264 at up to 1080p and 30 frames a second, made for chat and social. A 4K clip becomes a 1080p copy.
What happens to a slow-motion clip?
Smally leaves it as it is and the row says why: "This is a slow-motion clip. Smally would play it at normal speed, so it was left as it is." The copy of any other video has at most 30 frames a second.
Does it keep the HDR look?
The HDR an iPhone records (HLG) is converted so the colours look right on any screen. HDR10 and Dolby Vision profile 5 videos are skipped, and the row says why.
