Connected browser-local PDF workflow

v10.84 connects page organization, merge/split, rotation/deletion/extraction, conversion, compression, annotation, forms, metadata, page sizing, N-up/booklet/poster printing, comparison, and repeated header/footer work without replacing the established historical PDF engines.

PDF processing boundaries

These tools operate within browser memory and the capabilities of pdf-lib/pdf.js and the existing local engines. Encrypted, malformed, scanned, XFA, unusual forms, complex signatures, OCR-dependent documents, and advanced desktop-editor features can require specialist software. Always verify generated files before discarding the source.

How to use this PDF Grayscale Converter

Choose a PDF, select render DPI and JPEG quality, then rebuild the pages as grayscale images in a new PDF.

What the result means

Rasterize pages at a selected DPI, convert pixels to grayscale, rebuild an image-only PDF, and download the result.

Practical tips and limits

This is a raster conversion. It changes document semantics and can remove searchable/selectable text, links, forms, annotations, layers, and accessibility tags.
