Reduce PDF File Size
Make large PDF documents easier to share, upload and archive. Compress reports, contracts, invoices, assignments and scanned documents without requiring Adobe Acrobat or other desktop software.
Choose Your Compression Level
Pick from Light, Balanced, Strong, Very Strong, Extreme or Ultra compression to control the trade-off between file size and visual quality — ideal for scanned documents and image-heavy PDFs that need to be shrunk down for email or upload limits.
