Why Download Sample Files by Size?
Testing file uploads, network throughput, or storage limits? You need files of exact, known sizes. Our sample files are generated on-demand in real file formats — not random binary blobs — so they pass MIME-type checks, open in native applications, and behave like real user uploads.
Upload Testing
Validate file-size limits, progress bars, and error handling in your upload forms. Test with 1 MB, 10 MB, or 100 MB files.
API & Performance Testing
Measure transfer speed, timeout behaviour, and memory usage with precise payloads. Use JSON, CSV, or XML data files.
Automation & CI/CD
Automate file-based tests in your CI pipeline. Our sample files work with Selenium, Playwright, Cypress, and any HTTP client.
