Where the server lives

Stirling PDF in Rio de Janeiro

With Rio de Janeiro selected, your VPS with Stirling PDF runs in Mega's original data center, on our own network with a presence at the Rio internet exchange (IX.br) and redundant transit. It is the lowest latency for users in Rio, Espírito Santo and Minas Gerais, and our support team works in the same city as the server.

What is Stirling PDF

Stirling PDF is an open source web app for editing and handling PDF files. You open it in the browser, but your VPS does the work, so documents only travel between your computer and your server.

Its tools include merging and splitting files, reordering pages, compressing, converting to and from Word, images and HTML, adding watermarks, signing and password protection. It also has OCR, which turns scanned documents into PDFs with selectable text.

In the Mega installation, login is already enabled. Only people with an account can use the tools, and nobody else can use your server to process files.
