FAQ

About PDF Binarize

What is the difference between black-and-white and grayscale PDF conversion?

Black-and-white mode turns pages into distinct black and white regions and is suitable for text documents and ink-saving printouts. Grayscale preserves more tonal detail and better suits photos, shadows, and pale annotations. Compare the previews to ensure important detail is retained.

Should I choose Text priority or Ink-saving priority?

Text priority emphasizes readable strokes and suits contracts, exam papers, and scanned documents. Ink-saving priority reduces dark areas more aggressively and may sacrifice faint detail. Export and test-print a few pages before a formal print run.

Will binarization make every PDF smaller?

Not necessarily. File size also depends on source image resolution, compression, fonts, and object structure. Binarization mainly changes visual and printing characteristics and should not be treated as a dedicated lossless-compression tool.

Are files uploaded for PDF binarization?

No. Processing is local in your browser. Multiple PDFs are supported; a single result downloads as PDF and batch results as ZIP. It does not consume a cloud trial or daily quota.
