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.
