Large PDF files can be difficult to share via email or upload to websites. ApexPDF solves this problem by offering a free, advanced PDF compression tool. Our smart compression algorithms significantly reduce file size while preserving document quality, making sharing seamless.
We value your privacy. Unlike other services, ApexPDF compresses files locally on your device using WebAssembly technology. Your documents are never sent to a remote server.
Choose between 'Condense' for optimized structure or 'Photon' for image-heavy documents.
Compression happens in your browser. No data leaves your computer.
Adjust compression levels from Light to Extreme, and fine-tune image quality settings.

Condense removes dead-weight, optimizes images, and subsets fonts - best for most PDFs. Photon converts pages to images - ideal for photo-heavy/scanned PDFs but makes text non-selectable.
Balanced (recommended) offers great size reduction with minimal quality loss. Use Light to preserve maximum quality, Aggressive for smaller files, or Extreme for maximum compression.
