Make sure your file upload field’s Max file size is set high enough. The limit is configured in KB (kilobytes), not MB (megabytes), so you’ll enter a number in KB.
Quick conversions:
10 MB = 10,000 KB
15 MB = 15,000 KB
50 MB = 50,000 KB
100 MB = 100,000 KB
Recommended steps:
Open your form and select the File Upload field.
Find Max file size (KB) in the field settings.
Enter a value that matches the size you want (e.g., 15,000 for ~15 MB or 100,000 for ~100 MB).
Save and test with a file slightly below the limit.
Tips:
If you leave the limit blank, the default platform maximum applies.
If you see an error like “maximum 2,048 KB,” raise the limit (e.g., to 15,000 for ~15 MB).
For very large uploads, consider 100,000 KB (~100 MB) and ensure your storage/integration supports files of that size.
ℹ️️ The maximum file size you can upload in a form is 102,400 KB (around 100 MB).
You can also control the allowed File types and choose whether to enable Allow multiple file upload:
💡 If you need to let users submit files above the max limit, an alternative is to add a simple Text field where they can paste a link to any file-sharing service that supports heavy uploads.
