# JPMC-PDP Documentation from https://developer.payments.jpmorgan.com # Resources This page provides information on the formatting and decoding of check images returned by the check image API. ## Image format The API returns both the front and back images of a check as Base64-encoded strings. Base64 encoding converts binary data, such as images, into text suitable for transmission over the internet. ## Decoding Base64 string To render or save the images, clients must decode the Base64 string. Most programming environments provide built-in libraries or tools for decoding Base64. Once decoded, the images can be integrated into your system or workflow as needed. ## Related - For more information about check images, see [Overview](/docs/treasury/checks/capabilities/check-image/overview). - For more information about check image parameters, see [Parameters](/docs/treasury/checks/capabilities/check-image/payment-parameters). ## Next steps Learn how to [initiate a check image request](/docs/treasury/checks/capabilities/check-image/how-to/how-to).
