Job retention
2 hours
Temporary job folders expire automatically to keep storage tight and predictable.
Common questions
Frequently asked questions
PaperKit keeps the workflow simple: upload files, process them server-side, and download the results before the temporary job expires.
Upload rules
100 MB
The site enforces a clear request cap so people know what to expect before uploading.
Result indexing
Blocked
Preview, download, and result pages stay out of public search results.
How temporary jobs work
Each upload creates a tokenized job folder on the server so results can be delivered back to the same workflow without exposing a public directory.
Jobs expire automatically after two hours, which keeps download links short-lived and prevents old result pages from lingering after the task is finished.
- Result pages are marked noindex, nofollow, and noarchive.
- Download and preview routes only serve files registered to the matching job token.
- Expired jobs return a dedicated gone page instead of a broken file response.
Validation and safety
PaperKit validates file types and form inputs on the server before processing begins so unsupported requests fail early and clearly.
Malformed page ranges, password problems, and unsupported file combinations return friendly errors instead of silent failures.
- PDF-only tools reject non-PDF uploads.
- JPG to PDF accepts JPG images only.
- The total upload cap is 100 MB per request.
What each tool page includes
PaperKit is organized around complete landing pages instead of blank upload forms. Every major tool page includes a clear overview, step-by-step guidance, specifications, and frequently asked questions.
That structure helps visitors understand whether a tool fits their task before they upload any files.
