Size forecast
Pick a video and see the expected size instantly — plus why it shrinks: extra bitrate, 4K on a phone screen, HEVC.

Target size
Choose WhatsApp, email or Discord and it aims just under the limit. 47 MB becomes 10.2 MB — under WhatsApp's 16 MB on the first try.

Quality check
A phone shows 1080p, so 4K originals shrink with no visible difference. Compare side by side and pinch to zoom 1:1 before you save.

Batch
Sort by Biggest to see which videos take the most space. Select several and compress them in one batch — date and location are kept.

How it works
Your newest videos come first — or sort by Biggest. Each shows the size it will shrink to.
Keep the quality, hit a limit like WhatsApp's 16 MB, or set an exact size.
Save to Photos with the date kept, or share straight to WhatsApp or Mail.
