The default limit to upload files on your form is 1024 KB (1 MB), but you are able to change this limit, you only need to follow the steps on this guide to increase the upload size limit of your form:
The max size per file is 1 GB, you are able to upload a max size of 5 GB on your forms, but do note that this uploads use the space on your account and you should consider this when allowing your users to upload files with a large size, I would suggest you to integrate your form with a 3rd party service such as Dropbox, Google Drive or Box, so you will be able to delete your submissions with the uploaded files and get free space on your account, if you need more space than the current that you have, take a look to our pricing, there you will find the limits per account and you may find one that fits your needs.
