How to Validate a JPG File in Python

Since JPG is one of the most common image formats on the internet, you’re likely to encounter JPG images in your image processing applications. Validating these files before processing them in any way is critical to ensure they don’t pose a security risk or cause any monumental issues downstream. The below API solution will quickly validate JPG files in your workflow, and you’ll only need a few lines of code to call the service (complementary Python code examples are provided below for your convenience). When any JPG files are found to be invalid, this API will return specific information about the errors that were found, and it’ll provide warnings related to those errors when applicable.

To begin making your API call, start by running the command provided below to install the Python SDK:

pip install cloudmersive-convert-api-client

Once that’s done, include the imports and call the function:

from __future__ import print_function
import time
import cloudmersive_convert_api_client
from cloudmersive_convert_api_client.rest import ApiException
from pprint import pprint

# Configure API key authorization: Apikey
configuration = cloudmersive_convert_api_client.Configuration()
configuration.api_key['Apikey'] = 'YOUR_API_KEY'



# create an instance of the API class
api_instance = cloudmersive_convert_api_client.ValidateDocumentApi(cloudmersive_convert_api_client.ApiClient(configuration))
input_file = '/path/to/inputfile' # file | Input file to perform the operation on.

try:
    # Validate a JPG File
    api_response = api_instance.validate_document_jpg_validation(input_file)
    pprint(api_response)
except ApiException as e:
    print("Exception when calling ValidateDocumentApi->validate_document_jpg_validation: %s\n" % e)

Finally, to complete your API call, supply a Cloudmersive API key in the API key configuration step. You can get a free-tier API key by registering a free account on our website, which will allow up to 800 API calls per month with no commitments (i.e., once you reach that limit, the total will reset the following month).

That’s all there is to it — you can put your JPG validation needs to rest!
