How it works

Built for speed.
Tuned for quality.

01

The fastest compressor on iPhone

Compressly uses your iPhone’s built-in hardware video encoder instead of slow software conversion. A clip that takes other apps minutes is done in seconds — and it won’t choke or crash on long 4K recordings.

02

Pick your quality in one tap

Three simple presets cover everything: Low for the smallest possible file, Medium for everyday sharing, High when a video needs to stay sharp. No bitrate sliders, no codec menus — just choose and go.

03

Smart recommendations

Tell Compressly what the video is for and it picks the right settings — trimmed for WhatsApp and iMessage, sized for Instagram and social, or kept high-quality for archiving. The right balance of size and quality, without the guesswork.

04

Batch it, and watch the savings add up

Select up to 20 videos and compress them in one run, with live progress and a single summary of everything you reclaimed. A lifetime space-saved tracker keeps count of every gigabyte you’ve freed.

Our promise

Your videos never leave your iPhone.
Nothing is uploaded.
Your originals stay untouched —
because the work happens entirely on device.
