## Best for

Teams and individuals handling contracts, invoices, or scans who want Acrobat-level tools without uploading the files.

## Why it deserves attention

Stirling PDF bundles merge, split, sign, redact, OCR, compress, convert, and form filling into one interface, and runs as a desktop app, a browser app, or a Docker service behind your own firewall. Nearly every tool has a REST API, so document pipelines can be automated, and the interface ships in more than 40 languages. It has about 95,000 GitHub stars, frequent releases, and an active community. The community edition is free and self-hosted; some enterprise features are paid, and updates and backups are your responsibility.
