Need a different size?
5MB sample files
Common upload-limit ceiling for many SaaS apps and content management systems.
10MB sample files
The default body-size limit on many gateways and the cutoff most apps care about.
50MB sample files
Mid-range size where simple uploads start to fail without chunking or resumable transfers.
100MB sample files
Large file size — exposes timeouts, memory leaks, and missing chunked-upload logic.
500MB sample files
Very large file — required for streaming uploads, S3 multipart, and tus protocol testing.
1GB sample files
Stress-test territory — uncovers issues only large uploads produce, like progress jitter and OOM.
