Test Upload Limits

Check whether your web app, form, or CMS accepts files of a given size before deploying to production.

Benchmark Download Speed

Use 10MB, 50MB and 100MB files to measure download throughput and test CDN or server performance.

PDF Viewer Testing

Verify that your PDF viewer, browser plugin, or embedded viewer renders large and small PDFs correctly.

Email Attachment Testing

Many email providers limit attachments to 10–25MB. Use these files to quickly find where the cutoff is.

Frequently Asked Questions

Everything about sample PDF files and what they're used for.

What is a sample PDF file used for?
Sample PDF files (also called test PDFs or dummy PDFs) are used by developers and QA testers to verify file upload size limits, test download speeds, check email attachment restrictions, benchmark PDF viewer performance, and test document management systems with known file sizes.
How are the PDF files generated at an exact size?
Each PDF is generated in your browser using the pdf-lib JavaScript library. After creating the base PDF with content and metadata, the remaining bytes needed to reach the exact target size are added as a compressed data stream embedded in the PDF — a standard, valid technique that doesn't affect how the file opens or displays.
Are these valid, openable PDF files?
Yes. Every file is a fully valid PDF that opens correctly in Adobe Acrobat, Chrome, Firefox, Edge, Preview on macOS, and all other standard PDF viewers. The files contain real content, metadata, and conform to the PDF specification.
Why does the 50MB or 100MB file take a few seconds?
Large files (50MB and 100MB) require generating and padding a large amount of data entirely in your browser. This takes a few seconds of CPU time to build the byte array before triggering the download. The progress bar shows generation progress in real time.
Is there a 1MB or 5MB sample PDF I can download right now?
Yes. Click the Download button on the 1MB or 5MB card above. The file is generated instantly in your browser and the download begins automatically. No signup, no waiting, no ads.
Are these files safe to download?
Yes. The files are generated entirely in your browser using JavaScript — nothing is downloaded from an external server, and no data leaves your device. The PDFs contain only text content and padding data with no scripts or embedded objects.
