How Stirling PDF is hosted

Valebyte launches the application automatically in a managed container. You receive its URL and application access, but not root access to the host system.

info Overview

Stirling PDF is a self-hosted PDF toolkit that runs entirely on your own server, giving you 50+ PDF operations in a single web app. You can merge, split, rotate, reorder pages, compress, convert PDFs to and from images and Office formats (Word, Excel, PowerPoint via LibreOffice), run OCR to make scans searchable (via Tesseract), add or remove passwords and permissions, sign, watermark, edit metadata, flatten, repair and compare files — all without a single document ever leaving your machine.

Valebyte hosting model: Stirling PDF launches automatically as a managed application. Choose a region and resource plan; after checkout you receive the application URL and app-level access, normally within minutes. Valebyte maintains the host infrastructure. Root access to the host is not provided, and infrastructure backups are not enabled automatically.

quiz Frequently Asked Questions

Is Stirling PDF a good self-hosted alternative to iLovePDF or Smallpdf? expand_more

Yes. Stirling PDF covers the same everyday tasks — merge, split, compress, convert, OCR and more — with 50+ operations in total. The key difference is that every file is processed on your own server, so your documents never touch a third-party cloud.

Is there a login, and are my files private? expand_more

There is no login and no account: Stirling PDF is a stateless tool suite you just open in the browser. Every document is processed locally on your own server and is never uploaded anywhere, which makes it safe for contracts, IDs and financial or legal files.

How much RAM does Stirling PDF need? expand_more

2 GB of RAM is the sensible minimum. Basic operations like merge, split and compress are light, but OCR and Office conversions use LibreOffice and Tesseract, which are more CPU and RAM intensive. Very large batch OCR benefits from additional vCPU.

What can Stirling PDF actually do? expand_more

It offers 50+ operations: merge, split, rotate, reorder pages, convert PDFs to and from images and Office documents, OCR, compress, add or remove passwords and permissions, sign, watermark, add page numbers, edit metadata, flatten, repair and compare PDFs.

Can I use my own domain? expand_more

A standard application URL is provided after deployment. A custom domain is not included by default; ask support whether it is available for this application.

Does Stirling PDF upload my documents anywhere? expand_more

No. Everything happens on your own server — there is no third-party upload, no external API and no telemetry of your file contents. This is the core reason to self-host it instead of using an online PDF service.
