DOCUMENTATION & SUPPORT

Frequently Asked Questions

Is FryPDF available on the Microsoft Store?

Yes. You can install FryPDF directly from the Microsoft Store (ID: 9P5GW2Q81B33) for 1-click installation, sandboxed security, and seamless automatic updates on Windows 10 and 11.

Is FryPDF really 100% offline and privacy-first?

Yes. FryPDF has zero telemetry, zero analytics beacons, and opens zero network sockets. All document parsing, AcroForm computations, OCR processing, format conversions, and PDF compilation occur directly on your local CPU.

How do the 32 PDF tools work without modal popups?

Every tool in FryPDF opens in a dedicated full-page workspace within the Home dashboard. You get rich input file queues, live configuration sidebars, output previews, and 1-click chained navigation directly to subsequent tools without annoying dialogs.

What is the .frypdf file format?

.frypdf is a lossless JSON project schema that stores full vector coordinate systems, live LaTeX formulas, AcroForm bindings, and document metadata without rasterizing your artwork.

How does FOIA redaction work?

Unlike superficial black highlighter overlays, FryPDF physically strips the underlying text strings and vector paths from the compiled document content stream, replacing them with solid pixel fills and legal exemption tags.

Can I build batch automated workflows?

Yes. The built-in Batch Pipeline Workflow Builder allows chaining multiple operations (e.g. OCR scanned pages → Compress → Add Watermark → Encrypt) to process folders of documents in a single automated pass.

How do I run FryPDF on macOS if Gatekeeper flags the app?

When downloading binaries outside the Mac App Store, macOS may attach a quarantine flag. Move FryPDF.app to /Applications, then run this one-line command in Terminal: xattr -dr com.apple.quarantine "/Applications/FryPDF.app"

Is FryPDF in early development?

Yes. FryPDF is currently in an early active stage of development (v1.0.0-preview). While the core vector engine, document viewer, and 32 tool workspaces are functional, some features or complex edge cases are actively being refined and will be continuously enhanced in upcoming releases. Feedback and issue reports on GitHub are warmly appreciated!
