What is the upload file limit?

do you provide larger upload limits than 1mb?

Yes. You may change the file upload size limit from the upload field properties.

However, the free subscription plans are limited to store only 100MB of files in the account. If you need more storage space, you'll be required to upgrade your account to a paid subscription.
