Why I built it
Upload testing is repetitive: you need a 5 MB PDF, a CSV one byte over the limit, or a file with the wrong extension to verify MIME checks. Downloading random files from the internet is slow, inconsistent, and risky for privacy. I wanted a predictable, browser-local way to create those fixtures — and documentation that explains when to use them, not just a download button.
What this site is (and is not)
Dummy File Generator is primarily an educational resource for software testers and developers: guides, scenario playbooks, file-format notes, and blog posts about upload QA. The file generator is a companion utility that runs entirely in your browser.
It is not a file hosting service, a cloud converter, or a place to process sensitive production data. Generated files never leave your device unless you choose to upload them elsewhere.
My background
I work on web applications where file uploads, storage limits, and validation edge cases show up often. This site reflects problems I have hit in real projects: boundary sizes, MIME mismatches, timeout testing, and keeping test data out of production databases. The articles here are written from that hands-on perspective — not generic SEO filler.
Editorial standards
- Original intent: each guide or scenario explains a concrete testing job (e.g. 5 MB PDF boundary, padded CSV import stress).
- Honest limits: synthetic MP4/WebM shells are for upload/MIME probes, not Hollywood playback — we say so explicitly.
- Updates: when the product changes, I publish changelog-style notes on the blog.
Privacy & analytics (accurate disclosure)
File generation is local — we do not receive the files you create. We do use Google Analytics and Microsoft Clarity to understand aggregate traffic (pages viewed, approximate region, browser type). If advertising is enabled, Google AdSense may use cookies on editorial pages only — not on the bare generator UI. Details are in our privacy policy.
