When you hunt high and low for a video compressor app for Windows PC, macOS or iPhone Android, you'll be greeted by a boatload of apps to choose from. Randomly open one app website, and the tedious product introduction text will pop up in full screen. Not only would this cost you a couple of minutes to read one app introduction, but also confuse your judgement due to the similar exaggerated business expression they use.
Outwardly, all of them seem first-class. Yet, you know that's not the truth. You need to uncover the sides they hide from you. This post exists for this reason, unearthing the sides they don't write them out. Then you can reach your own conclusion about the "best" video compressor app after you get a complete cognition.

What else haven't developers told you:

Top Video Compressor Apps for iPhone & Android
The following video compression applications are mainly for iPhone (12/mini/Pro/Pro Max). Click here to have a glimpse of the top video compressor apps for Android phone & tablets.
1. Video Compress - Shrink Vids
This video reducing app stands head and shoulder over others thanks to its bulk compression feature, which even allows you to compress entire albums to save your iPhone space, esp. for 64GB iPhone 12. It also lets you customize video via bit rate & resolution adjustment.
Please note:
- You'll be charged at $4.99 for the upgrade and $0.99 to skip the ads. And you'll be asked to re-pay for this app if it crashes and you re-install it on your iPhone.
- This video compressor app for iPhone is designed to downsize video recorded by your original camera. Other video sources or videos being edited before are excluded.
- No option to see all videos in the camera role.
- It seems that no professional developer team accounts for the update on this app (reflected by user Kkb17 on Apple App Store).

2. Video Compressor
Compatible with iOS 13 or above based iPhone iPad iPod, this video compression software is a strong performer to compress iPhone videos, esp. 1080p, 720p HD videos with 3 modes: 720p (70% size off with medium image quality); VGA (save 80% of space with 480p sharp image quality) and Low (99% space saved at the price of low image quality, only 128p resolution). Beyond that, video trimming can be applied to further resize video footage.
Please note:
- It's awash with commercial ads.
- 4K 2160p video compression is not suggested via this app, for it would result in sudden crash now and then.
