iPhone
That "file too large" error from Mail or WhatsApp? Shrink the video first. One tap, smaller file, same clarity. No upload, no signup.
Compress without limits.
Shrink any video on your iPhone in seconds. Keep the clarity that matters, drop the file size that doesn't.
Built for the moment you need to send a video and the upload bar refuses to move. Email rejects it. WhatsApp warns you. Your storage is full again. One tap, smaller file, same video. That's the whole job.
What you can do
Compress MP4, MOV, and most common formats your camera roll holds. Shrink 4K and HD footage down to a size you can actually send. Keep audio in sync. Pick a target size or let the app choose a clean balance for you. Save the result back to your camera roll, or share straight to Mail, Messages, WhatsApp, Gmail, Instagram, TikTok, Discord, or anywhere else.
Why it works
The compressor runs locally on your device. Nothing uploads to a server. Your videos stay on your phone, which means no waiting on a slow upload, no privacy worry, no watermark stamped on the result. Everything stays yours.
Made for sending
Most people compress a video for one reason: to send it. So we built every step around that. Pick the file, choose how small you want it, share. The whole loop takes less time than reading this paragraph.
Made for saving space
A 4K minute of video can eat 400 megabytes. Most of that is detail you don't need on a phone screen. Shrink the same minute to 80 megabytes and your eye won't notice. Your storage will.
What's inside
Quality presets so you don't have to guess. A clean preview before you compress. Batch handling for multiple files. Original kept safe, we never overwrite. Quick share to every messaging and mail app on your phone.
For anyone with a phone full of videos
Parents who film their kids and need to send the clip to grandparents. Travelers with a camera roll heavier than their suitcase. Students sending project files. Creators trimming 4K down to upload-friendly sizes. Anyone who's ever stared at a "file too large" error and felt that small flash of irritation.
Privacy
On-device compression. No account. No tracking. No uploading your video anywhere. The file moves from your camera roll to your camera roll. Nothing else touches it.
