Security
Browser-first, with honest limits
PDFPerch minimizes data movement, validates generated files and separates completed tools from experimental integration boundaries.
Browser sandbox
Local tools use browser APIs, PDF libraries and Web Workers. Keep original files because browser crashes, low memory and damaged inputs can still interrupt processing.
Output validation
Core generators check PDF headers, EOF markers and page counts before starting a download. Users should still inspect critical legal, financial and printing output.
Security is not a slogan
Visual signatures are not certificate signatures. Cropping is not redaction. Password configuration is not encryption until a standards-compatible engine confirms it. These limitations are shown on the relevant pages.
