Native Media3-based compression
Compressor uses the native Media3 library rather than an ffmpeg wrapper, which the README presents as the basis for its speed and small footprint.
Compressor
Compressor is a native Android video compressor that works locally on-device, is ad free, uses Android System Photo Picker, and supports Share Sheet plus H.265/AV1 on compatible devices.
Overview
Compressor is a native Android video compressor focused on fast local processing, small app size, and a simple workflow. The project README describes it as lightning fast, ad free, and super lightweight, and the privacy policy says compression runs locally on the device.
It is built around Android’s hardware acceleration and the native Media3 library rather than an ffmpeg wrapper. The app is intended for users who want to compress selected videos on Android without granting broad storage access, internet access, ads, or tracking SDKs.
Features
Modern codec support
The app supports H.265 and AV1 on compatible devices, so it can take advantage of newer hardware and codec support where available.
Share Sheet integration
Share Sheet support lets you hand off compressed videos through the Android sharing flow instead of keeping everything inside the app.
Minimal dependency and permission model
The project states it uses no third-party libraries and no invasive permissions, including no storage or internet permission.
Small native Android app
The app is described as ad free, super lightweight, and under 10 MB, with a completely native Kotlin codebase.
Broad Android support
The README says the app works on Android 7.0 and up and supports reproducible builds.
Use Cases
Reduce file size before sharing
Use Compressor when you want a smaller video file before sending it through messaging or email, without uploading the original clip to a remote service.
Compress videos privately on the phone
Use the app when you want to keep video processing on-device and limit access to only the video you selected through the Android picker.
Take advantage of device codec support
Use it on supported hardware when you want modern codec options such as H.265 or AV1 rather than relying on a bulky software encoder.
Keep a minimal compression tool installed
Use Compressor if you want a lightweight Android app that avoids ads and third-party SDKs while keeping the workflow simple.
Pros and Cons
Pros
- Compression runs locally on the device, which keeps videos on the phone.
- No internet permission is requested and the privacy policy says there are no third-party analytics or advertising SDKs.
- The app supports Share Sheet handoff for a straightforward compression-and-share flow.
- The README presents the app as lightweight, ad free, and built natively in Kotlin.
- Support for H.265 and AV1 is available on compatible hardware.
Cons
- Only Android support is documented in the source, so it is not positioned as a cross-platform tool.
- H.265 and AV1 are available only on compatible devices, so codec support depends on device capabilities.
- The source emphasizes local compression quality and speed, but it does not document detailed export settings or file-format options.
