FAQ

Frequently asked questions

Quick answers about compressing, resizing, and sharing videos on iPhone and iPad.

How do I compress a video on my iPhone?
iOS has no built-in tool for compressing existing videos. Install Video Compressor and Resizer, select videos from your library, pick a quality level and resolution, and tap Compress — the smaller copy is saved to Photos in seconds. Learn more →
How do I reduce a video's file size without losing quality?
Keep the original resolution and choose Output Quality: Good. In our test it made 1-minute iPhone clips 57% smaller with a VMAF quality score of 97 out of 100 — identical to the eye on a phone. Learn more →
How do I email a video that says it's too large?
Email providers cap attachments at about 20–25 MB. Compress it to 720p at Output Quality: Good first — about 18 MB per minute of 1080p video in our test, and perfectly watchable. Learn more →
How do I compress a video for WhatsApp?
WhatsApp aggressively re-compresses large videos, which is what makes them blurry. Compress it yourself first — 720p at Output Quality: High — to control how the result looks. Learn more →
How do I send a long video from my iPhone?
Compression is the most reliable fix: a 10-minute video can shrink from over a gigabyte to a size Messages, WhatsApp, or email will accept — no cloud links needed. Learn more →
How do I free up iPhone storage without deleting videos?
Compress your library instead of deleting it. One minute of 4K takes 300–400 MB — compressing old videos routinely frees tens of gigabytes while every memory stays in Photos. Learn more →
How do I compress 4K video on iPhone?
Scale 4K to 1080p unless you'll watch on a 4K TV — on a phone the difference is invisible, and in our test the file got 82% smaller (421 MB to 74 MB per minute). Learn more →
How do I resize a video or change its resolution?
Select the video and choose a resolution percentage — 50% turns 4K into 1080p. You control the exact output size before compressing. Learn more →
Can I compress multiple videos at once?
Yes — batch compression processes dozens of videos in one run with the same settings. It's the fastest way to clean up storage. Learn more →
Are my videos uploaded anywhere?
Never. All processing happens locally on your device — no uploads, no servers, no account. See the privacy policy.
Is the app free?
Free to download and try. Unlimited use via an affordable subscription or a one-time lifetime purchase — no watermarks, ever. Get it on the App Store →
