Usage

Image

For Like Whatsapp Image Compression

import { Image } from 'react-native-compressor';

const result = await Image.compress('file://path_of_file/image.jpg', {
  compressionMethod: 'auto',
});

Here is this package comparison of images compression with WhatsApp

For manual Compression

import { Image } from 'react-native-compressor';

const result = await Image.compress('file://path_of_file/image.jpg', {
  maxWidth: 1000,
  quality: 0.8,
});

import { Video } from 'react-native-compressor';

const result = await Video.compress(
  'file://path_of_file/BigBuckBunny.mp4',
  {
    compressionMethod: 'auto',
  },
  (progress) => {
    if (backgroundMode) {
      console.log('Compression Progress: ', progress);
    } else {
      setCompressingProgress(progress);
    }
  }
);

    }
  }
);

  { quality: 'medium' }
);

API

Image

ImageCompressor

• compress(value: string, options?: CompressorOptions): Promise<string>

  Compresses the input file URI or base-64 string with the specified options. Promise returns a string after compression has completed. Resizing will always keep the original aspect ratio of the image, the maxWidth and maxHeight are used as a boundary.

CompressorOptions

• compressionMethod: compressionMethod (default: "manual")

  if you want to compress images like whatsapp then make this prop auto. Can be either manual or auto, defines the Compression Method.

• maxWidth: number (default: 1280)

  The maximum width boundary used as the main boundary in resizing a landscape image.

• maxHeight: number (default: 1280)

  The maximum height boundary used as the main boundary in resizing a portrait image.

• quality: number (default: 0.8)

  The quality modifier for the JPEG file format, can be specified when output is PNG but will be ignored.

• input: InputType (default: uri)

  Can be either uri or base64, defines the contentents of the value parameter.

• output: OutputType (default: jpg)

  Can be either jpg or png, defines the output image format.

• returnableOutputType: ReturnableOutputType (default: uri)

  Can be either uri or base64, defines the Returnable output image format.

Video

• compress(url: string, options?: videoCompresssionType , onProgress?: (progress: number)): Promise<string>

videoCompresssionType

• compressionMethod: compressionMethod (default: "manual")

  if you want to compress videos like whatsapp then make this prop auto. Can be either manual or auto, defines the Compression Method.

• maxSize: number (default: 640)

  The maximum size can be height in case of portrait video or can be width in case of landscape video.

• bitrate: string

  bitrate of video which reduce or increase video size. if compressionMethod will auto then this prop will not work

• minimumFileSizeForCompress: number (default: 16)

  16 means 16mb. default our package do not compress under 16mb video file. minimumFileSizeForCompress will allow us to change this 16mb offset. fixed #26

Audio

• compress(url: string, options?: audioCompresssionType): Promise<string>

audioCompresssionType

• quality: qualityType (default: medium)

  we can also control bitrate through quality. qualityType can be low | medium | high

Note: Audio compression will be add soon
