Stirling PDF performs the operations people normally upload confidential documents to a random website to get: merging, splitting, rotating, compressing, converting, OCR, watermarking and signing.
Hosting it yourself means a contract or a scan never leaves your infrastructure to be processed by a stranger.
What you get
Merge, split, rotate, reorder, crop and compress
Convert to and from images, Office formats and HTML
OCR with selectable languages, and text extraction
Watermarks, redaction, page numbers, signing and password protection
Running Stirling PDF on Autogineer Cloud
Stirling PDF is a one-click install here: choose it at checkout, set a root password, and the server is built, the software installed and configured, and published on its own HTTPS address — usually in about a minute, with the whole build streamed to your browser as it runs.
Installed and configured, not just downloaded. The build finishes only once Stirling PDF is answering on its port with a real page — a server that could not finish is reported as failed rather than handed over looking complete.
A working HTTPS address from the first minute. Your server is published at an address like stirlingpdf-vps.autogineer.com, with a valid certificate, so webhooks and OAuth callbacks work immediately. Your own domain can be added afterwards.
Full root over SSH. The one-click install is a starting point, not a cage: you can reconfigure Stirling PDF, install anything beside it, or replace it entirely.
Backups you can restore from. On-demand backups of the whole server on every paid plan, which for Stirling PDF means its data as well as its configuration.
Room to grow. Resize the plan as Stirling PDF grows, or rebuild the same server with a different app when the project changes.
Who it suits
Any business that handles documents it should not be uploading to a free web tool.
Getting started with Stirling PDF
When the build finishes, your server's page in the dashboard shows its HTTPS address, its root password and any sign-in details the installer set for Stirling PDF. The build console streams every step as it happens, so you can see exactly what was installed rather than taking it on trust.
The tool list opens with no sign-in. Drop a PDF onto the operation you want — merge, split, compress, OCR, sign — and download the result; the file is processed on your server and not retained.
Add your own domain from the same page when you are ready: point a DNS record at the server and the certificate is issued for you. The original address keeps working, so nothing you configured against it breaks.
Take a backup once Stirling PDF is configured the way you want it. A backup captures the whole server, so restoring one brings back Stirling PDF and its data together — and it is the only thing that will bring them back.
Frequently asked questions
Are my documents uploaded anywhere?
Only to your own server, which processes them and does not retain them by default. That is the reason to run it yourself.
Why does it need a larger plan than most tools here?
OCR and format conversion are genuinely CPU and memory hungry, and the OCR language data takes disk. The minimum on this page reflects real use rather than an idle process.
How long does it take to install Stirling PDF?
About a minute. Choosing Stirling PDF at checkout builds the server, installs it, and publishes it on an HTTPS address, streaming the progress to your browser as it happens.
What size server does Stirling PDF need?
At least 2 vCPU, 2 GB of memory and 15 GB of disk, which is the Business plan or larger. These are the figures the installer is tested against rather than the smallest configuration that will boot.
Do I get root access to the server?
Yes. Every server includes full root access over SSH on its own port, so you can configure, extend or replace anything the one-click installer set up.
Can I use my own domain with Stirling PDF?
Yes. Each server is published on its own HTTPS address the moment it is built — stirlingpdf-vps.autogineer.com for example, and you can point your own domain at it afterwards from the dashboard.
