How does PDF compression work?
PDF compression for Dropbox uses WebAssembly technology to process your files directly in the browser. Unlike cloud services, no file is sent to a server. The algorithm reduces embedded image weight, removes unnecessary metadata, and optimizes the internal PDF structure. The result: a lighter file, perfect for Dropbox, while preserving text readability and visual quality of graphic elements.
Compression Quality Levels
Light
20-40% reduction. Ideal for documents with few images. Quality nearly identical to original.
Medium
40-60% reduction. Good balance between size and quality. Recommended for most uses.
Maximum
60-90% reduction. Perfect for email or messaging attachments. Images are more compressed.
