Need a different size?

1MB sample files

Standard small-file size for testing email attachments, basic upload flows, and form validation.

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.

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.

Frequently Asked Questions

Why download a 100MB test file?

Large file size — exposes timeouts, memory leaks, and missing chunked-upload logic.

Are these files exactly 100MB?

This is a size-range page, not a claim that every file has the same byte count. It includes files between 80,000,000 and 150,000,000 bytes. Use the exact measured bytes and SHA-256 shown on each file card for boundary tests.

What formats are available at 100MB?

Documents, Video, Archives, Test files. Each format includes multiple variants — different content, encoding, or properties — so you can match the exact case your app needs.

Do I need to sign up to download?

No. Click any download button and the file comes directly from the CDN without an email or account form.
