losLab Software is an independent software developer specialising in native PDF and spreadsheet libraries for Delphi, C++Builder, Lazarus and Windows document-processing applications.
Since 2007, we have maintained source-code libraries for developers who need document workflows they can inspect, integrate, test and deploy without opaque hosted services or per-document runtime fees.
What we build
Our product family covers PDF viewing and rendering, PDF creation and editing, digital signatures, standards-aware validation, document preflight, spreadsheet reading and writing, and desktop or command-line document conversion.
How we support developers
Commercial library licences include Object Pascal source code, royalty-free application deployment, one year of updates and one year of email support. Product pages link to current documentation, release notes, evaluation packages and transparent licence tiers.
