How to use these limits in tests Find the limit your system (or the service you integrate with) enforces. Upload a file exactly at the limit, then one byte over — the “Test” link generates the second one. Check that the over-limit upload fails with a clear message, not a timeout or a 500 error. Ready-made sizes: test files from 100 KB to 100 MB . Unsure whether “5 MB” means 5,000,000 or 5,242,880 bytes? Use the file size calculator .
