LittlePDF vs Stirling PDF
Stirling PDF is the strongest privacy answer in this category, and it deserves to be said clearly: if you run it yourself, your files never touch anyone else's machine, and the Enterprise tier will even run air-gapped. It ships more than 60 operations, a REST API, pipelines, folder scanning, its own MCP server, SSO, audit logging, and native desktop builds for Windows, macOS, and Linux. This page is not an argument that we are more private than that. It is an argument about what it costs you to get there. Stirling's privacy requires a server, a deployment, and someone to keep both alive. LittlePDF's 18 client-side tools give you the no-upload guarantee in a browser tab, for the price of nothing, with no infrastructure attached.

Our verdict
Pick LittlePDF if you want no-upload PDF tools without running anything, plus AI and conversions when you need them. Pick Stirling PDF if you can host it, because self-hosting is a stronger privacy position than any hosted service including ours, and it is free for up to 5 users.

Where these numbers come from
Every figure above, with the page it was read on and the day it was read. Where we could not read a price on the vendor's own property, we say so instead of printing it as though we had.
- Stirling PDF free for up to 5 users, Server at $99/mo or $999/yr, Enterprise customVerified
- docs.stirlingpdf.com/Paid-Offerings/. Free is self-hosted with all PDF operations and community support. Server includes 100 users, sold in 100-user blocks, with support tickets, an external database, Google Drive, and OAuth2 SSO, and the page notes the annual plan saves $189. Enterprise adds air-gapped deployment with certificate activation, uptime SLAs, SAML2 SSO, audit logs, a usage monitoring UI, and a Prometheus endpoint. Read .
- Self-hosting costs more than its licenceOurs
- Not a price we can quote for you. The Stirling licence is one line; the server, the storage, the upgrades, and the person who owns all three are the rest of it. That total is why we think the honest comparison here is effort against effort, not dollar against dollar. Read .

Why Teams Leave Stirling PDF
No-upload tools with nothing to deploy
Stirling's privacy comes from the file never leaving your infrastructure, which is excellent and requires infrastructure. LittlePDF's 18 client-side tools give you the same no-upload property in a browser tab: merge, split, compress, rotate, organize, watermark, sign, redact, protect, unlock, and eight more read and write the file locally, with no server involved at all.
AI that reads the document
Stirling manipulates PDFs and does it well, but it has no layer for understanding them. LittlePDF adds OCR on Gemini vision and chat, summarize, translate, table extraction, and key-information extraction on Claude, available on the free tier within a daily credit budget.
Verifiable rather than assertable
The self-hosting audience is right that a hosted tool's privacy claim is worth exactly as much as your ability to check it. So check ours. Open the network tab, run a client-side tool, and watch for a request carrying your file. There will not be one. Our security page walks through the steps and lists which tools do upload, because 18 of the 36 do.
The Real Differences
Stirling PDF needs a server, a deployment, and someone to maintain both. LittlePDF needs a browser tab, and 18 of its 36 tools still never send your file anywhere.
Stirling's free tier stops at 5 users and its Server tier is $99 a month or $999 a year. LittlePDF is free for one person with 500 credits a day, and $6.99 a month if you want more.
Stirling has no AI layer for reading documents. LittlePDF includes OCR, chat, summarize, translate, table extraction, and key-information extraction, on Claude and Gemini, from the free tier.
Stirling asks you to trust a deployment you maintain, which is the right trade for some teams and impossible for most people. LittlePDF asks you to verify a claim in your browser's network tab, which takes about thirty seconds.
When Stirling PDF is the better pick
No tool wins every case. Here is where Stirling PDF is the honest, better choice.
- You can host it. Self-hosting is a stronger privacy position than any hosted service, ours included, and we are not going to argue otherwise.
- You need air-gapped operation, SAML2 SSO, or audit logs. Those live on Stirling's Enterprise tier and have no equivalent here.
- You want to automate at volume with a REST API, pipelines, or folder scanning against a directory you control.
- Your team is five people or fewer, in which case Stirling is free forever and we cost money above the free tier.
- You want the source. Stirling is open source and LittlePDF is not, and for some buyers that settles it on its own.
