Sample PDF Files by Exact Size
Testing file upload boundaries requires strict mathematical precision. A standard PDF file size fluctuates unpredictably depending on its fonts and image compression. These test files solve that problem.
We programmatically inject safely ignored binary blobs directly into the PDF body (outside the `xref` streams) before generating the trailer. This ensures they perfectly meet their target byte count—from a 20KB micro-file up to a massive 5GB stress test—without corrupting the document's readability in standard parsers like PDF.js or Adobe Acrobat.
Small 20 KB
A minimalist 20KB PDF for fast unit testing and bandwidth-constrained systems.
Small 50 KB
A 50KB baseline document suitable for lightweight applications.
Small 100 KB
A 100KB document, representing a typical text-only contract.
Small 500 KB
A 500KB document, roughly the size of a standard report with basic styling.
Medium 1 MB
A standard 1MB payload, representing an average text-heavy contract.
Medium 5 MB
A 5MB document representing an average image-embedded PDF.
Medium 10 MB
A 10MB file, perfectly tuned to test common corporate email attachment limits (usually 10MB to 25MB).
Medium 25 MB
Auto-generated PDF file.
