Why
Decent PDF tools are either paid or upload your documents to someone else's server. ManiPDF does the work on your machine: no file ever leaves the computer.
Technical decisions
- pdf.js for rendering: the same engine Firefox uses, battle-tested against real-world PDFs, which rarely follow the spec closely.
- Ghostscript for compression and reprocessing. Bundling an external binary inside Electron means solving per-platform packaging and child-process handling.
- TypeScript throughout, because a document editor that corrupts a file over an
undefinedis unforgivable.
