Instead of a subscription

Self-hosted alternatives to Smallpdf

Smallpdf converts, compresses and signs PDF files in a browser, once the file has been uploaded. The toolbox here performs the same conversions locally, so a contract or a scan never reaches a third party.

The bill

The subscription against a server

Both figures are editable, because only you know which of them you actually pay. The server is sized from the figure the recipe recommends — the same one the catalog calls a comfortable fit on your profile — and not from the cheapest row of a price list.

Subscription, $ per monthReplaced byServer, $ per month

Stirling PDF asks for 4 GB of RAM, 2 vCPU and 10 GB of disk — $24 a month on DigitalOcean Basic.

The difference

Per month: $14
Per year: $168
Over three years: $504

The subscription wins on price by $168 a year. What hosting it buys you here is the data, not the money.

Not counted: your own time, a domain, and a backup kept anywhere other than that same server. A machine you already run costs nothing extra — set the server to zero.

Migration

What changes when you host it yourself

The data stops leaving your network, and so does the responsibility for it: backups, the restore you have actually tested, and the disk it all sits on.

Feature parity is never exact. Read what each recipe states about limitations and the smoke test before planning a migration.

The bill turns into work: updates, certificates and an eye on the release notes. The catalog shows how much of that each recipe asks for.
