Undersize : Video Compressor

Oversize video? Make it Undersize — send to WhatsApp, mail or any app without switching. Exact size, fully offline, one time payment, no subscription.

Compress a too-large video without leaving the app you're in.

Share any video to Undersize from WhatsApp, Messages or Mail, tap one button, and get it back small enough to send. No switching apps, no re-importing.

ONE TAP TO FIT

• WhatsApp — 16 MB
• Discord — 10 MB free tier
• Email — 20 MB, and we account for the ~⅓ that attachments grow in transit
• Or set any size you want

WE HIT THE SIZE Most compressors guess. We check the finished file and re-encode if it missed, so "fits WhatsApp" is a promise rather than a hope.

LOOKS RIGHT, NOT JUST SMALL Proper HDR handling, correct portrait video, no washed-out colour. Set the resolution you want, mute the audio, trim before compressing.

PRIVATE BY DEFAULT Everything happens on your iPhone. No uploads, no account, no servers. Your location and device details are stripped from the compressed file, so sharing a video doesn't share where you filmed it.

ONE PAYMENT No subscription. No ads. No watermark. Ever. One free compression a day; unlock unlimited compressions and batch mode with a single purchase you own forever.
