This document contains current content limits and request quotas for the Cloud Vision API. This page will be updated to reflect any changes to these restrictions and usage limits.
The Cloud Vision API enforces the following usage limits:
|Image file size||20 MB|
|JSON request object size||10 MB|
|Images per request||16|
Base64-encoded images may exceed the JSON size limit, even if they are within the image file size limit. Larger images should be hosted on Cloud Storage or at a publicly-accessible URL. Note that base64-encoded images can have a larger file size than the original image file (usually about 37% larger).
The current API usage quotas for the Cloud Vision API are as follows (and are subject to change):
|Requests per minute||1,800|
These limits apply to each Google Cloud Console project and are shared across all applications and IP addresses using that project.
Lower quotas can be set per user in the Google Cloud Console.
You can edit your quotas up to their maximum values by selecting EDIT QUOTAS from the Quotas page of the Google Cloud Console page. To request an increase above the maximum quota, edit your quota with your requested increase and justification and submit your update. You will be notified when your request has been received. You might be contacted for more information regarding your request. After your request has been reviewed, you will be notified whether it has been approved or denied.
