Compressor

Android Arsenal Build Status codecov

Compressor is a lightweight and powerful android image compression library. Compressor will allow you to compress large photos into smaller sized photos with very less or negligible loss in quality of the image.

Gradle

dependencies {
    implementation 'id.zelory:compressor:3.0.1'
}

Let's compress the image size!

Compress Image File

val compressedImageFile = Compressor.compress(context, actualImageFile)

Compress Image File to specific destination

val compressedImageFile = Compressor.compress(context, actualImageFile) {
    default()
    destination(myFile)
}

I want custom Compressor!

Using default constraint and custom partial of it

val compressedImageFile = Compressor.compress(context, actualImageFile) {
    default(width = 640, format = Bitmap.CompressFormat.WEBP)
}

Full custom constraint

val compressedImageFile = Compressor.compress(context, actualImageFile) {
    resolution(1280, 720)
    quality(80)
    format(Bitmap.CompressFormat.WEBP)
    size(2_097_152) // 2 MB
}

Using your own custom constraint

class MyLowerCaseNameConstraint: Constraint {
    override fun isSatisfied(imageFile: File): Boolean {
        return imageFile.name.all { it.isLowerCase() }
    }

    override fun satisfy(imageFile: File): File {
        val destination = File(imageFile.parent, imageFile.name.toLowerCase())
        imageFile.renameTo(destination)
        return destination
    }
}

val compressedImageFile = Compressor.compress(context, actualImageFile) {
    constraint(MyLowerCaseNameConstraint()) // your own constraint
    quality(80) // combine with compressor constraint
    format(Bitmap.CompressFormat.WEBP)
}

You can create your own extension too

fun Compression.lowerCaseName() {
    constraint(MyLowerCaseNameConstraint())
}

val compressedImageFile = Compressor.compress(context, actualImageFile) {
    lowerCaseName() // your own extension
    quality(80) // combine with compressor constraint
    format(Bitmap.CompressFormat.WEBP)
}

Compressor now is using Kotlin coroutines!

Calling Compressor should be done from coroutines scope

// e.g calling from activity lifecycle scope
lifecycleScope.launch {
    val compressedImageFile = Compressor.compress(context, actualImageFile)
}

// calling from global scope
GlobalScope.launch {
    val compressedImageFile = Compressor.compress(context, actualImageFile)
}

Run Compressor in main thread

val compressedImageFile = Compressor.compress(context, actualImageFile, Dispatchers.Main)
