pdfty's compress tool shrinks PDF files using Ghostscript's optimized image and font handling. You typically save 60-90% on photo-heavy PDFs, and 20-40% on text-heavy ones, while keeping text crisp and tables readable.
Choose between three quality presets: Web (lowest, ideal for email), Print (balanced), Prepress (smallest reduction, near-original quality). Most users pick Web — the savings are big and visual quality stays good.
Free up to 20 MB upload size, no watermark, no signup. Compression runs server-side and finishes in seconds. Files are deleted within 1 hour.
