OctoZip typically reduces file sizes by 60–90% depending on source quality, codec, and preset. A 50MB Instagram video can often reach 5–10MB with barely noticeable quality loss.
Never. All compression happens 100% on your device. Your videos never leave your phone. We have no servers that process your media.
OctoZip supports MP4, MOV, AVI, MKV, and WebM. Output is MP4 (H.264 or H.265) for maximum compatibility across platforms.
Time depends on video length, resolution (4K takes longer), codec (H.265 is slower but smaller), and your device processor. Newer phones with hardware encoders are significantly faster.
Open any video → tap Share → select OctoZip from the share sheet. The video opens directly in OctoZip. After compression it saves straight to your gallery.
Free includes access to core presets and all major features. Pro unlocks advanced codec settings, enables unlimited batch compression, and removes ads.
Google Play → your profile → Payments & subscriptions → Subscriptions → OctoZip Pro → Cancel. Pro access continues until the end of the billing period.
