Encoding a file in Base64

The Vision OCR API and OCR API support images encoded in Base64. Encode your image or PDF file in Base64:

UNIX

Windows

PowerShell

Python

Node.js

Java

base64 -i input.jpg > output.txt

C:> Base64.exe -e input.jpg > output.txt

[Convert]::ToBase64String([IO.File]::ReadAllBytes("./input.jpg")) > output.txt

# Import a library for Base64 encoding.
        import base64
        
        # Create a function that encodes a file and returns the encoded result.
        def encode_file(file_path):
          with open(file_path, "rb") as fid:
            file_content = fid.read()
          return base64.b64encode(file_content).decode("utf-8")

// Read the file contents into memory.
        var fs = require('fs');
        var file = fs.readFileSync('/path/to/file');
        
        // Get the file contents encoded in Base64
        var encoded = Buffer.from(file).toString('base64');

// Import a library for Base64 encoding.
        import org.apache.commons.codec.binary.Base64;
        
        // Get the file contents encoded in Base64.
        byte[] fileData = Base64.encodeBase64(yourFile.getBytes());

import (
          "bufio"
          "encoding/base64"
          "io/ioutil"
          "os"
        )
        
        // Open the file.
        f, _ := os.Open("/path/to/file")
        
        // Read the file contents.
        reader := bufio.NewReader(f)
        content, _ := ioutil.ReadAll(reader)
        
        // Get the file contents encoded in Base64.
        base64.StdEncoding.EncodeToString(content)

In the request body, include the contents you got after encoding an image or PDF file in Base64:

{
            "folderId": "b1gvmob95yys********",
            "analyze_specs": [{
                "content": "iVBORw0KGgo...",
                ...
            }]
        }
