Base64string size is too large in payload

I'm trying to upload big files as multipart, so I convert the blob to base64string (by dividing the file to 5 MB chunks), however when I want to send it to the API the size is much bigger than the real size, when I copy the base64string to a text file and save it, the size is about 7 MB but when I try to post it, the size is more than 13 MB!!

Here is the code:

private UploadFileChunk(fileName: string, base64Chunk: string, partCount: number,uploadId:string): Promise<any> {
    const dataToSend = {
      fileName,
      partNumber:partCount,
      fileChunk: base64Chunk,
      uploadId
    };

    return this.props.service.post(`apiURL/api/uploadchunks`, JSON.stringify(dataToSend));
  }

Can we send raw data instead of base64? I'm looking for a way of sending binary to my api – Ramin Ahmadi Oct 27 '19 at 13:39
Not if you plan on using JSON as data carrier. You'd have to revert back to multipart file upload. – fredrik Oct 27 '19 at 14:11
Thanks, do you have any sample? – Ramin Ahmadi Oct 27 '19 at 16:06
